Polygon AX Trail Bike

Was going to wait until i had all of the bits and built it up to start the thread, but I’m sitting here with a glass of wine and meh. For about 7 or 8 years now i have had a Giant Reign as my mid travel trail bike. Build thread here: [url]http://www.rotorburn.com/forums/showthread.php?150496-Spooky-is-bringing-the-Reign[/url] Admittedly it didn’t get much use with the Cove being taken for DH runs and the Scott for DJ/4X stuff. But since moving to Melbourne i have been riding more XC/AM sort of stuff, and so i pulled out the Giant again. Now its certainly not a bad bike, but it has its limitations. First of all its a 6″ trail bike with geo from 2005, and then slackened out with 36s at the front for ~67ish deg head angle. Kind of means it wallows around a bit. Plus the HV shock just blows through its travel. Still i quite like it, and ill probably keep it around with the forks for kicks.

But in the end I wanted to upgrade to some newer gear, something that is designed around a 160mm fork rather than being forced to use one etc, and with some of the new standards like ISCG tabs and tapered steerer. Plus I figured that this might be a last hurrah for 26″ so i may as well get in on the act.

I had a few $$$ around in the kitty, and this had been on the forums for a while, so i made an offer and had it sent down:

Its in pretty good nick, few scratches here and there but nothing major. Weighed it tonight though, and when people say that the Polygons are a little heavier, they aren’t wrong:

[img]http://gallery2.plebeians.net/d/36287-2/20140908-223048-iPhone_001.JPG[/img]

Thats with the RP23 shock, and a Shimano rear axle. No headset. 4.26kg… ouch. The Reign frameset looks light at 3.45kg with shock and headset.

Ill be transferring all of the gear over from the Reign, although i may be getting new forks, just need to see how that pans out. Need to wait on the new headset and the axle adapters for the Hopes from the UK.
Thats about it for now, will update when stuff comes in etc.

P.s. Knuckles, this was that ’13.

I doubt you will be disappointed by the choice. From what I can tell they are pretty strong too and plenty smooth on easy going DH tracks like the one at Ourimba. Not sure how they would handle a serious rock garden or significant drop/case, but from my experience with them over the last 6 months they are a good performer.[/QUOTE]

Sounds like it will be fun then.

The next piece of the puzzle came today:

[img]http://gallery2.plebeians.net/d/36308-2/20140912-145502-iPhone.JPG[/img]

Had a slight confusion with a friend who wanted some Pikes, I thought he wanted me to order them, and he thought he was ordering them. So we ended up getting 2 pairs, so im just keeping one for myself. 160/130 DPA RCT3s. Should be a good match with the frameset, and luckily with a quick swap with my mate they are the right colour for the frame.
Plus the rear axle adapters arrived from CRC this morning courtesy of a 2.2kg tub of High5 meaning the parcel was sent DHL not RM. Along with the axle adapters was this little guy:

[img]http://gallery2.plebeians.net/d/36297-2/20140912-115726-iPhone.JPG[/img]

76g worth of chainring protection.

Now the only thing left to come is the headset, because i had to go the blingy one didnt i….

Hehehe, yeah……probably Neezy’s cousin.

Was having a cruise of Pushys the other day, looks like they cleared out most of their stock with that sale. Hopefully they’ll top up again soon.[/QUOTE]

Yeah, i struggled to make the $30 freeship threshold a few weeks ago. Ended up topping it up with a BBall inflating needle of all things.

Anyway, was in the garage tonight fixing up the XTC and couldnt help but do this:

Budget XTC XC Bike

Slight update, picked up a cheap set of XT brakes and IspecB shifters, so fitted those up a couple of weeks ago. Currently my usual bike for Lysterfield:

[img]http://gallery2.plebeians.net/d/36257-2/20140906-222835-iPhone_001.JPG[/img]

Rides pretty well with the shorter stem, but i think i need to tune the tyre pressures a bit, some of the climbs get a bit squirrelly. Will have to learn to climb properly I think.

Got around to weighing it in the current incarnation:

[img]http://gallery2.plebeians.net/d/36292-2/20140909-123516-iPhone.JPG[/img]

11.6kg, so a bit heavier than i thought it would be, albeit with heavier Airwave tubes, pedals and bottle cage.

Starting to consider weenieing it out a bit more too. First thing to go will the the big ring, and just go 2x up front. I don’t find myself using the 44T for my type of riding anyway.
The Jetblack Rockets arent tubeless atm, would need rim strips etc, so i won’t do that just yet, although ill consider it if i find a set of 26″ rim strips cheap.

Any other suggestions for cheap and easy weenie?

Giant Reign AM Bike

Bit of a thread resurrection:

[img]http://gallery2.plebeians.net/d/35752-2/20140619-002005-iPhone.JPG[/img]

Brought the bike out of storage at the start of the year, and stripped it back to rebuild it as a Trail/Enduro bike.

Big changes are the Hope/Stans wheelset, 1×10 XT drivetrain and brakes. Almost the only things that remained were the Hone cranks, 36s and the frame.

Rides pretty well as a trail bike, and i havnt found much reason to upgrade to a newer frame yet (as much as i want to). Certainly doesnt bomb DH like the Cove Shocker i had in between, and doesnt climb like my mates Trek Gary Fisher Paragon, but its a good trail bike, mainly needs tweaking of pressures to get a bit better.

Fitted the OneUp 42T and RAD cage tonight:

Plus cut down a e13 TRS backing plate to make a taco only bash guard:

Will see how it all goes on the weekend, but seems to be shifting well on the stand.

Retro Demo DH Bike

Long story, but I have always wanted an older Demo, now i know that the geo isnt all the rage these days, and that some of the early ones had to deal with cracking issues in the shock cage, but ever since I saw the Collective guys railing them in The Collective and ROAM, i knew I wanted one. So about 6 years ago i bought one, but never did anything with it, and sold it off to buy a Cove Shocker, which found a miserable end at Thredbo.
However, recently ive been able to pick up an old 2006/7 Demo 9 frame off a friend who was splitting his bike out. So here i am building it up in a bit of a haphazard way, but really trying to build the bike that i wanted from 2006.

The core of it of course is an old Specialized Demo 9 DH frame:

[img]http://gallery2.plebeians.net/d/35942-2/20140730-103628-iPhone_001.JPG[/img]

I have paired it up with some 2010 Fox 40s from on here:

[img]http://gallery2.plebeians.net/d/35861-2/20140718-181641-iPhone.JPG[/img]

The rest of the bike is still coming together, although most of it will be the M810 Saint gear from the Cove, plus part of a DeeMax wheelset that I have had lying around for ages. Only problem with that is its a 135mm rear end, and im needing 150mm for the Demo. Until i find an old Silver/Yellow 2006 150mm DeeMax i have picked up a cheap Gravity rear wheel for the build to get it going.

Will post up more photos of gear as it comes in and goes together.

Some parts came in for this in the last week and i had a chance tonight to go screw some of it together:

FSA Gravity guide, with my old Hone cranks and an E13 guide ring:

[img]http://gallery2.plebeians.net/d/35976-2/20140804-204700-iPhone_003.JPG[/img]

Plus mounted up the seat post and saddle and the Saint mech with the new jockey wheels.

[img]http://gallery2.plebeians.net/d/35981-2/20140804-204700-iPhone_004.JPG[/img]

Decided to go the old IGA Black and Gold colour scheme 🙂

Headset arrived today, so i pulled out my hugely expensive headset press and went to town:

[img]http://gallery2.plebeians.net/d/36036-2/20140808-211010-iPhone_001.JPG[/img]

Then i just assembled the front end:

[img]http://gallery2.plebeians.net/d/36048-2/20140808-211010-iPhone_003.JPG[/img]

Funn Fatboy bars with RSX Light stem, M810 brakes, and Jet Black grips.

Had to run back upstairs, so it went back on the wall for now:

[img]http://gallery2.plebeians.net/d/36063-2/20140808-212530-iPhone.JPG[/img]

Still waiting on the gold end caps for the shifter cable, and then i can get started on the last few little bits and pieces.

Budget XTC XC Bike

Rode into work via the Yarra trails today:

[img]http://gallery2.plebeians.net/d/35991-2/20140805-112737-iPhone.JPG[/img]

Seatpost bolt gave up the ghost too, so i finished off the ride with just the sheared end holding it together….

So i needed a new seat post, and i grabbed one cheap from T7:

[img]http://gallery2.plebeians.net/d/36067-2/20140812-214429-iPhone.JPG[/img]

Couldn’t resist more red anodising.

Plus i grabbed another stem while they were on sale, as the Crank Bros just didn’t quite feel right, so I’m experimenting with a 65mm rather than 80mm reach; as a slight bonus its 38g lighter. Just astounds me how light these stems are for such a chunky item.

[img]http://gallery2.plebeians.net/d/36072-2/20140812-214429-iPhone_001.JPG[/img]

Mmm billet aluminium:

[img]http://gallery2.plebeians.net/d/36082-2/20140812-214428-iPhone.JPG[/img]

Massive steerer stack for now as i decide whether ill stay with that length or not.

Budget XTC XC bike

So i was resisting the temptation to weenie out, but it appears that Chops’ influence is too great.

I needed new discs anyway and so i grabbed Ashimas from Pushys cheaply to both fulfil the new disc part of the equation, and to shed a few grams:

[img]http://gallery2.plebeians.net/d/35966-2/20140804-204700-iPhone_001.JPG[/img]

Had a spare 160mm front IS adapter lying around too so i got 140mm for the rear to see how it would go:

[img]http://gallery2.plebeians.net/d/35961-2/20140804-204700-iPhone.JPG[/img]

Now 10.5kg.

Budget XTC Cross Country Bike

Since im now living in Melbourne, and the closest trails (Yarra and Lysterfield) just dont warrant a 6″ trail bike all the time, i decided to build up an XC oriented hard tail, rather than nicking my wife’s Yukon or trying to XC on a DJ/4X bike.

Built this up on a tight budget:

[img]http://gallery2.plebeians.net/d/35916-2/20140726-163000-iPhone.JPG[/img]

Its an absolute hoot, pretty light, rolls well, jumps reasonably and can climb better than I can.

Specs:
2006/07ish Giant XTC3 frame
Fox 32 100mm CTD Evo
Jetblack Rocket wheelset (High Roller & Larsen TT)
M770 XT drivetrain bar the SLX shifters
M615 Deore brakes
Giant composite bars, Crankbros Iodine 1 stem, JB Lockon grips.

Pretty basic build really, but has come in under $500 with some judicious Farkin trawling, and picking up various bits around the country. Wasnt really trying to make a light build either, but it weighs in at 10.7kg with the M540 pedals and cheapo Airwave tubes. Could be lighter if i weeny out, but dont think i can really be bothered too much.
Its an enjoyable bike for my first XC hard tail, and should be good fun to come.

Havnt had much time to work on this for a while, but had a couple of hours today.

Did up the new brake fluid res’s with new lines and res’

[img]http://gallery2.plebeians.net/d/34680-1/_7260025.jpg[/img]

Resprayed the tank, and remounted it, and also flared the lines for AN fittings

Fitted the new wing mirrors

[img]http://gallery2.plebeians.net/d/34692-1/_7260028.jpg[/img]

Started setting up the new datalogging stuff, 100psi sensor there

[img]http://gallery2.plebeians.net/d/34696-1/_7260029.jpg[/img]

Plus this arrived for some more fun

[img]http://gallery2.plebeians.net/d/34684-1/_7260026.jpg[/img]

Need to go out and get more fuel line for the connections in the spare tyre well and under floor, and then i can finish that off. Really need to source a few wiring bits so i can finish off the engine bay loom, and then ill have to redo some of the interior loom too. All fun and games.
Oh and the exhaust is half done, ish.

Garage Takai IPRA AE86

Update has certainly been a long time coming, and that is mainly because i have done approximately SFA to the car since Nationals. I basically threw it back together again with a new sprung brass button clutch so it could be transported over to Vic on a car carrier. Since then it has just sat on stands for 8 months while i have been busy with the rest of life. In the intervening period i have sold off the current ECU setup, and started collecting stuff for the upgrades while travelling around the world. Firstly:

[img]http://gallery2.plebeians.net/d/34202-2/img0924123371.jpg[/img]

Haltech Sprint 500 from Dale, DTM mirrors and various connectors from Goodwood FoS stands, Racepak interface cable and 4 sensor addon, Deutsch HDP 20 29 pin bulkhead connector and some other bits.

[img]http://gallery2.plebeians.net/d/34197-2/img0924123344.jpg[/img]

Stainless exhaust bits and an Ultraracing panhard rod that i picked up in Malaysia on our way back, with new Whiteline bushes.

[img]http://gallery2.plebeians.net/d/34222-2/img0924123590.jpg[/img]

Small assortment of AN fittings and fuel filter etc that i have picked up from various sources for the new fuel system.

On the cards now is the following:
[LIST]
[]Wire in new Haltech []Wire up Racepak Dash to Haltech CAN bus
[]Redo engine loom with Deutsch QR connector []Build new rear exit exhaust
[]Redo entire fuel system with new hardlines and AN fittings throughout []Redo rear suspension with different rate springs and new panhard
[]Build new oil catch can setup []Replace front calipers to change braking ratios
[/LIST]

Have a few other bits and pieces to do as well, just tidying up some parts, and making it generally more reliable (knock on wood).

Currently trying to decide on two things though, firstly where to put the QR and secondly where to put the oil catch can. Options below:

[img]http://gallery2.plebeians.net/d/34225-2/img0924123550_001.jpg[/img]

Thinking that the QR would be good in the right hand spot as its easy to get to and would mean that i can get a nice gentle 90deg curve out of the wiring loom. However its right ontop of the extractors. According to Deutsch the connector is good for 125degC, and i woudl probably heatshield it too, but still not sure. The AS connectors are only 150deg too, so im probably worrying over nothing. Thoughts?

For now though have some photos of the car from Nationals:

Garage Takai IPRA AE86

Well thats the end of another year of racing for me.

Nationals weekend has come and gone with some good racing and some bitter disappointment. The car was performing quite well in the first qualifying session until it started bucketing down, managed to get my fastest qualifying lap in as a warmup lap before it started bucketing down properly, and then the V band clamp came of the exhaust and it dissappeared, never to be seen again. So we welded the primaries to the secondaries before Quali 2
Second qualifying session went pretty well, although i had a weird ignition issue at the end of that session. Basically it would hit something like ignition cut at ~5500rpm and wouldnt go anywhere.
Before the first heat we changed the coils and plugs and it seemed that the ignition problem was fixed, at least mostly.
The first heat showed up something a bit more annoying, we had a weird issue with it hitting redline oddly, but it was only happening around 7700rpm, so i just thought it was the ignition problem back with vengance. So we fiddled around with it some more, changed dwell settings and again its seemed to be fine while free revving.
Went out in the second heat and it just got worse. Quickly realised that it was actually the clutch slipping not the ignition dying. So after that race we started to pull the gearbox out, only to find that it got about an inch off the engine and then wouldnt go any further at all. Just jammed up solid.

Packed it in for the day and retired the next morning. Got it home after the end of the day and after dinner i pulled the engine and gearbox. After working through the starter motor hole i eventually managed to remove all 6 pressure plate bolts. This is what i found:
[IMG]http://a3.sphotos.ak.fbcdn.net/hphotos-ak-snc7/s720x720/308345_10150464205150944_646995943_10816860_604287785_n.jpg[/IMG]

Bang, the clutch had let go in fairly spectacular fashion. I think the main chunks of the friction material were only being held in place by the protruding rivets. And im not sure whether the center damage was done by us reefing the box around to try and get it out, or whether it was done in car. Either way its busted.
The reason the box wouldnt come out was that the spigot bearing was jammed on the end of the input shaft, and that was holding hte friction plate together enough. When i started pulling the engine out the second of those springs fell out of the bellhousing 🙂 and the other had fallen out when we loaded it onto the trailer.

What i really should have done is looked at the data trace from the datalogger and i would have seen this:

[img]http://gallery2.plebeians.net/d/33446-1/rpmclutchslip.PNG[/img]

The green trace is the RPM and you can quite clearly see it slipping a lot from 7500rpm onwards. In the later races this started from about 5500-6000rpm and would just slip to redline.

Oddly enough this isnt the first time ive made an Exedy clutch go bang in this way, back in 2006 i did this:

[img]http://gallery2.plebeians.net/d/6925-1/DSC00383.JPG[/img]

Back then the friction material jammed up the clutch entirely and i couldnt disengage the clutch at all. Thankfully this time it held together enough for the two heats i did on Saturday.

Ohwell, thats the end of another year for me. Next year ill be moving to Vic, and hopefully we can start over again 🙂

Hoping to have the car rebuilt soon at least for transport. Thinking about doing a few upgrades while im at it 🙂
