brake problem help pelase

[motomagII]

right just built me ride up with new 36t chainring qith 1`3 tooth freewheel .got brand new evolver for rear .prob is chain is just touching the caliper all the time .if i put the chain really tight its okay but the chain is too tight for my liking .
my q is what brake sits down lower than evolver by few mm .that works as well as one too without spending loads of cash as ive already spent 30.00 on evolver
cheers guys

i ran a 39tooth on it and was good to go.

[motomagII]

what brake caliper did u use?
yeah im running a 36 and determined its staying on too as the chainring cost me 30 quid or so .lol

[harris]

39 front with evolver

[motomagII]

those 3 extra teeth would do it asd its very very only just rattling on it when riding .its annoying though

[harris]

u can run the evolver with a brake plate in caliper hole as ive used before with slick cable

Fly do a low profile brake but its expensive, better to change the gearing Greg

dingo is right the fly is a great u brake  not cheap though

dont any of the ad990 magic or hombres sit lower
i really dont wanna change the gearing .

got the freewheel on and no removal tool and the chainring cost bit too .

will it be real prob if its just slightly rattling on the caliper when riding .not rubbing just flex on chain when bouncing around?

16 stone riding it is hard .not good but will get some stick as im no where near the word smooth lol

hi mate i have a ad990 brake jay

Question is were is the brake sitting ? On the chain stays or seat stays ? I run 30-11 with an ad990 on the chain stays with a low profile bolt from billys bikes and thats ok .
If your brake is on the chain stays it should be no were near the chain but if it is on your seat stays then your gearing is to big not to small what meens that your brake is on the angle and your chain is catching were the blocks go on the brake ? If so it probably doesn't mater what brake you get you may still have the problem .
What bike have you got  ? Any pics of this problem ?

Fly brake is well low. The new evolvoer looks lower and there is also a new delelition brake that looks low. The brake rub is why most frames have the brake at the top (under the seat stay) now. Frames like flys and S&M LAF have been well thought out and you can still run the brake on the chain stay with small gearing. I had a frame that the chain rubbed on the brake and I just cut a patch of old tyre and zip tied it to the brake bolt. It also stopped the cranks from spinning on no footers!
