GT rear brake mounting

[HUTCHMAN]

Your thoughts please...i got a rather nice ali GT box stay frame circa 1998. The only brake the frame will take is a caliper,but the hole for the caliper spindle is about 8mm(being lazy,measured it with litluns plastic ruler)...am i looking at knocking up a small shim or an alternative rear caliper? was it ACS that made a larger spindle caliper?

ACS boa has a large spindle, your frame might have been drilled for one

Easier to find with the larger spindle 

[HUTCHMAN]

not been drilled..the frame is NOS.

If its the frame I sold you, I may have the original caliper somewhere?

yes it is buddy!  be interested to hear from you on this. Any idea what the caliper is ?

very strange for a late 90's gt frame not to have a ad990 or canti/v brake mounts

any pics?

That GT is going to look sweet built up Dave, light as fook too

after a little research it seems you have a gt speed series jr expert frame

http://www.ebay.com/itm/GT-SPEED-SERIES-JR-EXPERT-FRAME-FORK-CRANKS-CRUPI-BARS-CAMPAGNOLO-BRAKES-/300701200497

hence why it has no brake mounts and has a different brake mount bridge to the normal speed series frames

heres a normal gt speed series brake mount bridge

a road bike brake will work, you can get them for £10 upwards, they have a 6mm bolt and a 8mm shafted allen key nut, check the pic in the link to see what i mean
