Mark W Posted March 9, 2005 Report Share Posted March 9, 2005 Ahoy hoy! I'm currently aiming to buy some Tensiles (maybe) for my T-Pro, but I don't know what BB to get with them. It needs to be 68mm x _ _ _ mm, but I don't know what because I've only ever used splined cranks once before. I'm running an Eno freewheel too, btw. Thanks for any help, Mark.

Danny Posted March 9, 2005 Report Share Posted March 9, 2005 Well what bb are u running currently witht he squares? You will probably need the same/next size up :blink: Quote Link to comment Share on other sites More sharing options...
Mark W Posted March 9, 2005 Author Report Share Posted March 9, 2005 It's a 68x127.5mm BB, but I didn't know if the length of the actual splines on the crank arm affected it much or...er...whatever :blink: Quote Link to comment Share on other sites More sharing options...

On my T Pro, with a 12t on the back, musclemans with asc claws on the front on a 127.5 sq taper bb, the freewheel teeth are a few cm across to the right from the teeth on the sproket (which IS on the right way round before anyone suggests it) Quote Link to comment Share on other sites More sharing options...
Pauly Posted March 9, 2005 Report Share Posted March 9, 2005 68X128mm mate :blink: Pauly Quote Link to comment Share on other sites More sharing options...
andyroo Posted March 9, 2005 Report Share Posted March 9, 2005 68X128mm mate :blink: Pauly ← I dont understand what you getting at, 127.5 means the freewheel is too far out on my T Pro, and not in line with my rear sprocket. I want to know if that is the case with Marks T Pro too. Quote Link to comment Share on other sites More sharing options...
Hobnobs Posted March 9, 2005 Report Share Posted March 9, 2005 (edited) I dunno bout marks, but mine is out with my 127.5mm BB, you can see the chain changing direction when it gets to the cog at the back :blink: Edited March 9, 2005 by Hobnobs Quote Link to comment Share on other sites More sharing options...

Is the bike completely as it was from the shop, or did you putt the larger bb in yourself? if so, what was the original bb size? im guessing 122ish... :angry: Quote Link to comment Share on other sites More sharing options...
Hobnobs Posted March 9, 2005 Report Share Posted March 9, 2005 I bought it myself, thinking it would be a good idea to get the longest i could. My chain rubs on the frame, and i think it might lead to it cracking there eventually. The old one i think was about 122 ish. Quote Link to comment Share on other sites More sharing options...
bacon Posted March 9, 2005 Report Share Posted March 9, 2005 get a 122.5 try all one - they last well and are good for the price. Quote Link to comment Share on other sites More sharing options...
Mark W Posted March 10, 2005 Author Report Share Posted March 10, 2005 My chain line was wank, 'til I did my right-side crank bolt up to 80N/m (it should theoretically be 35). It's stretched the taper out enough so the crank's far enough up the spindle so the chain-line's almost straight. I only did it 'cos it wore the f**k out of the side of my Eno ring :turned: It's a b*****d though, BB wise. I *think* 122mm is too narrow, but I just don't know :) I think I'm gonna try and swipe a Tensile + BB setup at Bike now, seeing as I get paid the Thursday before the show. Moneys = happys.

JT! Posted March 12, 2005 Report Share Posted March 12, 2005 (edited) Well i ran a 113mm bb on my old da bomb, which is the same as the t-bird. And, it did actauly fit :) . Sure the cranks hit the stays whenever you applied forse on them, but they fit (Y) . I am now running 124mm BB on my t-lite, which fits fine, i haven't got loads of room between the stays and the end of my cranks, but its loads enough, so that there wont be any problems. I wouldn't go for anything less than 124, that for me is perfect. My chain is quite close to rubbing on my frame, but it has a few mill clearence. I think the t-pro frame might be slightly wider than my t-lite, so something between 124, and 128 would be good. 126 would be perfect. :P Edit: I'm running the 170mm tensiles with an eno. They are the non uci ones. :unsure: Edited March 12, 2005 by JT! Quote Link to comment Share on other sites More sharing options...
