To get the ball rolling:

Is there an easy way to remove the main pivot pin in the XCR?

Author:  cyfa2809 [ Fri Oct 05, 2012 1:13 pm ]
Post subject: 

Ooo thats a toughie, there are a couple different variations on the main pivot as i recall (bearing differences/bushes). But you mean the main sleeve?
I think i used another sleeve to knock it through. Otherwise a very good fitting socket?

Worked a treat. nice one :)

Oh thats good. Think thats how i did it before. I say very close fitting as the sleeve isnt massive thick etc.

Exactly. The rusty tent peg could only go so far :)

Is the seat post loose and rattle-y in the tower on the STS XCR?

.. bought a frame and the seat post seems too small.

Done up the clamp & it slips in the tower.

The next size up won't fit :(

Having the seat tower crack, like on the XCRs, worries me.

No wonder there's so few of them around now.

Considering an i-drive at the moment; couple of questions: what's worth looking out for? Anything common that fails that's hideous to replace? Secondly, how do you size this frame? I'm looking, I guess, for a small or medium (my Zaskar is a 16" - inside leg is 30"). Any guidance as to what size I'd need and the best way to measure it?

Anything useful - cheers :)

Found out the sizing info. Posting it here in case it's of use to anyone :)

Source: http://forums.mtbr.com/gt/original-i-drive-riders-still-out-there-680510-9.html

Quote:
They said the frame measurements for the XCR bikes (or your i-drive team) was not based on the seat tube length since it does not have a continuous seat tube. They said they use the top tube length to create a sizing chart for the rider. So they have made a cross-reference chart to help.

Quoted directly from the manual :

Traditional frame size
Relative i-Drive frame size
i-Drive effective TT length

14.5 or 16"
Small
21.5"

17, 18"
Medium
22.7"

18, 19"
Large
23.4"

20, 22"
X-Large
24.3"

Be wary of frames around 2001 as they were prone to cracking around the seat post clamp area and shock mounts. Not sure why but I had a 2001 idrive and zaskar crack around the seat post clamp and have heard of many doing so.

There's usually a sticker on the frame or a size near the serial number.

Hi everybody

First post here with my brothers old 1999 XCR 3000 which I am restoring to a rideable state if not better than original.

- new RS Monarch RT3 shock coming
- rebuild of front RD Judy forks, new seals etc
- new headset, Hope or Adheaset
- new pads
- rebuild the i-Drive
- sand blast of rear triangle then anodised red at work

Couple of questions to guys might have the answer to--->

What is the diameter of the front derailleur band?
Is it possible to use external BB cups or even Hollowtech stuff?
What pin spanner do you use for removing the main pivot caps?

I want to go to 2 x 10 speed hopefully, hopefully possible?

Thanks

Brilliant thanks very much. That leads me onto a 10 speed setup. What's the deal with using external cups with the i-drive, shouldn't be any interference right?

no issue that i can see

If you're referring to external BB cups then there's no issues. I've fitted an external XT BB on my wifes idrive with no probs at all.

You could mail them and see if they would take a card payment or something like that?

Betd is all here, not strictly a full kit but one could be bought in more bits i guess? (Though full bearing units/cups etc.).

Right I am going to undertake a restoration of my brothers xcr4000 which will involve possibly stripping the idrive. I may alsoget the frame stripped and coated in which case it will have to come out

Hi everybody, I am about to buy my unicorn : a GT STS XCR 2000, size L !

But I am a little bit suspicious about this disc caliper position, don't you ?

Post subject:  Re: GT XCR idrive thread - owners bikes and tech support

I would be very concerned as they never came with a disc mount on this frame

I would be worried about what damage welding the disc tab onto the rear end has caused

(There is a genuine rear end on eBay for one of these atm £35 and I can help with shipping to u )

Post subject:  Re: GT XCR idrive thread - owners bikes and tech support

Not in fabrication yet, but front triangle is allready on the way to home.
I think that easier way for this project is to buy a standard fat bike, with belt drive and multi gear hub, in order to swap the frame for my xcr one, and to take all measurement for making custom rear triangle.
So, now looking for a cheap belt drive multi speed fat bike, complete !

Like the idea. Might be tricky..

Nearly built an STS XCR, but the seat pipe snapping was a concern.

Was considering making a custom seat piece. Ended up parting it out.

Good morning I have just joined the XCR / Idrive club having bought a XCR 4000.

Unfortunately it has a rough bb and of course the drive side threads are seized. The whole assembly has been removed and the threads are soaking in Wurth Rostoff.

I am a bit wary of applying significant pressure on the BB when fitted as all the force seems to be transmitted to the relatively small dogbone bolts.

What's the best way to proceed please?
