Dave Sutton Posted February 22, 2010 Report Share Posted February 22, 2010 I am going to be on a low budget for a while so will onza t bird cranks fit a czar mod frame without me having to take a chunk out of the frame? so it doesnt look like this Quote Link to comment Share on other sites More sharing options...
Revolver Posted February 22, 2010 Report Share Posted February 22, 2010 That issue would be solved with a longer BB, which might be cheaper than those cranks. Quote Link to comment Share on other sites More sharing options...
Alex Dark Posted February 22, 2010 Report Share Posted February 22, 2010 Yeh they weill fit...a wide 120mm+ square taper BB wil be needed. Like Revolver says, a long ISIS ffw compatible bb (128mm or more ) would probably work out cheaper, plus Isis is a far better system...

Dave Sutton Posted February 22, 2010 Author Report Share Posted February 22, 2010 so they wont fit if i dont buy any extras to make it fit? Quote Link to comment Share on other sites More sharing options...

They will fit if your existing bottom bracket is wide enough to allow them to clear the chainstay. Otherwise a longer BB will be needed.

Dave Sutton Posted February 22, 2010 Author Report Share Posted February 22, 2010 i didnt think the onza bird had a square taper bb? Quote Link to comment Share on other sites More sharing options...
Alex Dark Posted February 22, 2010 Report Share Posted February 22, 2010 i didnt think the onza bird had a square taper bb? I have no idea, but you put Onza t-bird cranks in the first post; which are most assuredly square taper cranks.... Quote Link to comment Share on other sites More sharing options...

Revolver Posted February 22, 2010 Report Share Posted February 22, 2010 (edited) im abit confussed with what that has to do with the topic? The point is, he can probably avoid what has happened in the picture and avoid buying cranks by buying a longer BB. Get it? Here is the proof - Onza t-bird crankset - £40 Trialtech Race Square Taper BB, £12 So, if he's wanting the t-bird cranks, he must have a square taper BB already. So, he must have square taper cranks already. Therefore, if he spends £12 on a looooooooong BB that will cause his current cranks to clear the frame, he's avoided spending another £28 on cranks that might not necessarily solve the problem. I win. Edited February 22, 2010 by Revolver Quote Link to comment Share on other sites More sharing options...
Mark W Posted February 23, 2010 Report Share Posted February 23, 2010 If he's already got an Onza taper BB, it'll most likely be a 127.5mm BB already, so I'm not sure a longer one would make much difference. Equally, I'm not entirely sure it'd clear the BB yoke just 'cos of how big the sprocket/bashring is. Quote Link to comment Share on other sites More sharing options...
Revolver Posted February 23, 2010 Report Share Posted February 23, 2010 I had a short onza BB in a t-rex, too short so it caused the chainring to foul on the chainstay when properly tightened. Quote Link to comment Share on other sites More sharing options...
LukasMcNeal Posted February 23, 2010 Report Share Posted February 23, 2010 My onza bb was only 122mm when I had it in my tpro. Quote Link to comment Share on other sites More sharing options...
