At the moment im running 9/27 if I drop to 26 how much rear wheel movement will I aquire? My rear tyre is rubbing on my brake so i need to move it back. Will that help or should I go 25/9?

Well 25/9 is nearer to the 44/16 "standard" & would allow the wheel to go back a bit, although have you looked at taking any extra spacers that may be in the brake blocks out on the inner brake arm side? This would mean adjusting the cable more thereby moving the brake arms away from the tyre. What tyre & brakes are you running?

glen i reckon if ya had smaller inner washers on the brake blocks ya might get a smidge more clearance mate
even if ya have to file the buggers down

was just thinking if ya have less washers ya could adjust the brake to move the arms away from the tyre to get clearance

That's what I was getting at, pads nearer the brake arms means adjusting cable to bring pads back to where they were will move the arms from the tyre, like it clears when you pull the lever.

I'm sure you've asked before about a 2.1 tyre on the rear of an LTF?

You're right a 2.1 tyre isnt much taller than a 1.95 but its fatter so you'll have clearance issues with the brake

I tried a KHE 2.1 tyre on the rear of both mine and my lads LTF's.... wouldnt clear the brake on either

Mine has 28/10 gearing, fly brake, regular chain

My lads 25/9 gearing, odyssey evolver brake, half link chain.... you'll more than likely need a half link if you go with 25/9 gearing

I tried smaller washers on the brake, it didnt work...

The chainstays on an LTF are'nt wide enough apart at the brake mounts compared with other frames

Hope this helps...

Cool you got it sorted, for now! A lot of frames seem to struggle to get anything over 1.95 in the back, but then again way back when anything over 1.75 used to give the same problems!
