LEON Posted February 13, 2007 Report Share Posted February 13, 2007 Do i need a wide one? I've only got a rac face 118mm, obviously crank arm/brake was never an issue on the zebdi.I'm also running a middle burn bash with 24t ring, anyone know from experience if i'll have problems?Leon Quote Link to comment Share on other sites More sharing options...
James Quigley Posted February 13, 2007 Report Share Posted February 13, 2007 Dunno about the bash but you may have trouble with the cranks hitting the brake cylinders.I know I did, but if you've got a narrowish rim you might be safe.

LEON Posted February 13, 2007 Author Report Share Posted February 13, 2007 Got a ronnie/reggie rear (which ever is bigger) wide but not huge like the koxx ones, cheersLeon Quote Link to comment Share on other sites More sharing options...
James Quigley Posted February 13, 2007 Report Share Posted February 13, 2007 you might be okay then.I had a ronnie with middleburns on a 128mm BB and was fine.I now have a 07 Echo with try-alls and there's quite a bit of clearance.So to sum up with the narrower BB you might just make it.

LEON Posted February 13, 2007 Author Report Share Posted February 13, 2007 I'll use worn down pads if i have to Leon Quote Link to comment Share on other sites More sharing options...
RobinJI Posted February 13, 2007 Report Share Posted February 13, 2007 I'm running a 122mm BB, with my RaceFace cranks (about the same offset as burns) and mine are close to the slaves on a DX32 (same width as the Onza, 38mm). That's with new ZOO! pads. With older pads I recon I'd get away with a 118mm BB. Quote Link to comment Share on other sites More sharing options...
philking Posted February 14, 2007 Report Share Posted February 14, 2007 I am using a 127.5mm bb with 'burns and it is VERY VERY close to my break cylinders, i even had to gring off part of my break pad so i could set the break up. Probably because they are really old square taper cranks, and go onto the bb further that newer ones. But be safe and get a wide one.

Blommah Posted February 26, 2007 Report Share Posted February 26, 2007 (edited) My cranks are far too close to the cylinders, so i have to buy new bb aswell as new brake pads soon, whats the pros and cons on long/short bb? Would the chainline be ok on a 128 mm bb?What width is it? 68 or 72 mm?.Got a typhoon 26" aswell with older middleburn isis cranks.cheers.

LEON Posted February 26, 2007 Author Report Share Posted February 26, 2007 (edited) Its all built but needs gear ratio/chain line and bb sorting, chain line looks like it'll be fine on 128mm long as the sprockets around the middle/outside of the free hub, mines on the inside so my chainlines poorly, but yea my crank arms are too close to the cylinders, got about 2mm Ordered a truvativ giga pipe from tartys today, i think most bb's do 68 or 73mm shells, 73 just gives a bit more tyre clearance/wider cnc yoke etc.Leon Edited February 26, 2007 by LEON Quote Link to comment Share on other sites More sharing options...
