My litespeeds got gears, it just doesn't get ridden much.

Planing on getting more geared bikes even (a proper light 29er and maybe even a 29er fully)

I recently replaced all of the linkage bearings in my Trance (which cost $80 for 10 bearings from Dougal at Shockcraft FWIW). If an average bike mechanic charges say $60/hr, there is no way in hell you could do that job in under half an hour! Unless the guy worked for McLaren perhaps?

IMO when it comes to pressing bearings, slowly and surely is the way to go...

though if you really want to go 10 speed and keep your 9 speed rear der (say it's a mega $$$ xtr for example) you can run 10 speed ROAD (flat bar) rear shifter (since like 9spd mtb/road and 10spd road they have the same rear pull ratios).

Downside would be keeping your current front (left) shifter which could look a bit ugly (cos the road front ders have a different cable pull to mtb too) - then again you could always man up and go 1x10 :thumbsup: :D


No just aquired a Trek 29er which is 10speed but it has some naff sram rear mech i plan to swap over some parts off the 9 spd but fancied keeping the 10spd rear.

is the 9 speed front crankset campatable or is there something diff with a 10 speed?

Nah just get a decent run up and go for ramming speed.

Are you going 2x10? I've recently built a GF Carbon 29er fully with direct mount derailleur (SRAM X0 2x10) and found it impossible to get satisfactory outer limit without replacing the limit screw with a much longer one.

I'm in the process of converting my GF carbon fully to 2x10, once sheppards sort their shit out and send the XTR FD I ordered ( no spare sram ones in the country I'm informed ). I'll be interested to see how the limit thing plays out.

If you're running a shimano crank with pressfit / bb30 adaptor then the chainline may differ slightly...

I really wasn't that impressed with the build quality of the GF is built for a customer. It also cracked through both the chainstay assembly and later the seatpost.

sram 2x10 cranks with the factory pressfit/gxp setup. had to go with an XTR fd due to the afore mentioned sram shortage. That said The XTR is designed to work with a triple as well as a double, so if the chainline is a bit wide we might avoid the limit screw issue you encountered.

fingers crossed that my bike holds together, I'm on the first warranty replacement. ( was a 2010 sf100, now on a 2011 with no issues so far. ) Is your guy the original owner? the GF/trek warranty has been pretty good in my experience

XTR comes in 2 variations - one for triple, one for double, and they're apparently not interchangeable.

Are there any disadvantages to running a chainguide thats mounted on a bottom bracket as apposed to running a chain guide on ISCG mounts?
I'm looking at a E*thirteen LG1 chainguide second hand for my Enduro, but the chainguide is ISCG 05 and my (2008) Enduro only has the old ISCG mounts. Though the chainguide I'm looking at also has a BB mount adapter, but I was wondering if it would somehow have disadvantages.

You require crank removal to get to the BB to make any adjustments.
