Foldable tyres seem to get real wide if you fully inflate them so I'm guessing the FAF's will do the same.

Not much help I know, but hey.

The FAF are a little thicker walled than the KHE and pretty much hold thier true width so you might be okay.

Are you thinkg the FAF-K or FAF (wire)?

They should advertise that you can run fat rears if brakeless.
I had the same problem with a FIT S3 I had before my LTF.

I tried 990, proper, and fly brakes, the fly had the best clearance.

Post by: lodge on April 22, 2009, 03:25 PM: My LTF is 25/9 and the rear wheel is almost slammed, I did manage to just get clearance with the 2.1 KHE but after getting a few punctures I found it was so difficult to set it up again it wasn't worth the hassle, If there was a slight run out on the tyre it fouled the brake and I had to start again deflate, inflate etc.

On the S3 I filed down a 990 to get clearance but I wasn't prepared to file my Fly brake down.
If you really want a fat rear tyre on it you could go down the file your brake route.

Post by: Bettyswallocks on April 22, 2009, 05:46 PM: Glen it wont fit, you'll need a skinny rear on an LTF if you wanna run a brake

When i built mine up i left the brake till last, 2.1 KHE the fly brake wouldnt fit

Gotta Mac 2 1.5 loads of clearance (actual size is 1.9 dunno why KHE call em 1.5)

Fook knows why S&M call the LTF fat tyre friendly... cos it aint... :idiot2:

Just fitted a FIT FAF-K 2.1 to a FIT Eddie 2 XXL frame with an Odyssey EVO II brake and it's got masses of clearance...I know it's a different frame, but the tyre does hold it's width well.

Anyhow, thought it might be usefull to someone...
