Probably A Really Stupid Question

I bought some old Raceface Turbine LP's a few weeks ago, then a Filthy ard guard a few weeks later, asuming the rockring would just fit, but the spider on the cranks is much too big/rockring too small

Do these cranks come in some sort a compact setup or what? How can the rockring be too small?!

Forgive my daftness :$

Ta!

These cranks appear to have a 110 mm B.C.D ( bolt circle diameter ) , a useful way of ensuring that customers purchase purchase the same brand's accesories . Race Face do make bashguards , but it'd be a shame to leave the 'ard guard unused . How about the chainring itself - does that fit O.K ?

Its 5 arm right? I guess its that the ard guard is made for compact drive cranks, which most (modern) 5 arms are, and i guess the raceface's you've got are a bit old school and are not compact drive. You could either get compact drive cranks or a big arse bashguard designed for non compact drive, but it will be along the lines of the size of a 4 arm 22t bashguard...so quite big.

Thats exactly right...the older cranks had a far larger BCD , so had to be run with a larger bashring (normally around a 32t bashring diameter

B..But, it's exactly the same cranks and bash Hawziee always used back in'th day

So the Turbine LP's are available in compact?

If 110bcd is jumbo, whats compact?
