race face isis bb fitting

......wouldnt it be a 5mm spacer?......

No. It's a 2.5mm one.

wouldnt that then only make it 70.5mm, what am i missing here!!!?

The difference between 68mm and 73mm BB shells is divided between both sides - 2.5mm/side.

Any pictures of the snapped Turbines? Always good to document the failures of parts that do not fail as often as some. Post them up if you have them.

Good point, I run an old set of forged Turbines sometimes (arm length is engraved rather than stamped so I assume older than some). I know the original (CNCed from billet) broke as did most billet cranks, but I thought the forged/CNCed ones were nigh-on indestructible.

I hope the forged ones don't break because I've got a set on my SS (in 180mm). :shock:

Generally they only have a driveside spacer. Some Truvativ ones do have a rubber o-ring for the non-driveside which is only fitted if you have a 68mm BB shell.

Today I fitted a raceface isis SRX bb...

It went in a frame with a 68mm BB shell. The 2.5mm spacer sits drive side behind the flange (if you use a e-type BB mount f mech OR a BB mount chainguide, lose the spacer). In a 73mm shell, there is no spacer used and you cant use an e type f mech or BB mount chainguide...

If you want to use an e type f mech/bb mount guide with your 73mm BB shell, apparently there is a FR/DH BB for 73mm shells and this application...

Well, thats what my raceface instructions said....

Probably no use at all...

Friendly bump for request for broken Turbine pictures. People with large numbers of sets of Turbines (me!) would like to keep track of the types of failures these things are suffering from. Did they break mid-arm? Spider? Pictures please!
