GT BB axle length

[Wold Ranger]

Can anyone advise what axle length Orginal steel GT's ran with in the BB got a nice frame and need to build it!

As far as I know, the BB axle length is determined by the cranks rather than the frame... someone may correct me though!

Both! depends on chainstay flare too. Think it'll be 113 or 115 mm but just checking. Race face LP turbine crankset, which have a lot of offset

Will check my old GT Psyclone later to see what I was running.

I had a GT Zaskar with M900's and the axle was 107mm!
Worked perfectly..

Nice cranks! I seem to remember that GTs had a shell width of 73mm. Turbine LPs usually run a 107mm bb (at least my mates ones do).

No its 68, but the consensus seems to be 107 mm for the axle, which is short for old skool. It is a fairly early Reynolds Chromo frame tho.
