Muel Posted October 29, 2008 Report Share Posted October 29, 2008 Depends how long the bb is and what cranks you've got, I had a set of Echo 6061 cranks with a tensile and no spacer or bashring, and it only just cleared the BB, it was less than half a mm away.

monkeyseemonkeydo Posted October 29, 2008 Report Share Posted October 29, 2008 No real way of knowing without knowing what cranks, bash and BB axle length you're running. Quote Link to comment Share on other sites More sharing options...
Daveee Posted October 29, 2008 Author Report Share Posted October 29, 2008 Umm, Tensile cranks and BB is 50mm i think and not too sure on bash i think its a Zona Quote Link to comment Share on other sites More sharing options...
Mark W Posted October 29, 2008 Report Share Posted October 29, 2008 The BB is either going to be 68mm or 73mm wide (The width of the bottom bracket on your frame), and the spindle is measured seperately from end to end, e.g. 128mm for most front freewheel setups. So your BB is probably either a 68x128 or 73x128, but without actually measuring it it'd be hard to tell. Are you running a freewheel at the moment?

eskimo Posted October 29, 2008 Report Share Posted October 29, 2008 You can get budget Onza bbs from Tarty at £14 posted. In 127.5mm length i think it was, (the longer length) will provide enough clearance for the setup. I presume it's square taper needed?

Muel Posted October 29, 2008 Report Share Posted October 29, 2008 My old was a standard T-Pro one and was 122.5.If you're buying new cranks you'd be much better off getting an ISIS setup though. Quote Link to comment Share on other sites More sharing options...
Mark W Posted October 30, 2008 Report Share Posted October 30, 2008 you, square taper i looked on the Onza website and the Bb is from a T-Pro and it said its 50mmThe 50mm is the BB rise, I'm guessing. That's the geometry of the frame, not the actual BB unit. Quote Link to comment Share on other sites More sharing options...

The Duck Posted October 30, 2008 Report Share Posted October 30, 2008 Lol. As I think has already been said, there is more than one kind of 'standard onza BB', measure it.You sig is pretty funny. Quote Link to comment Share on other sites More sharing options...
neotropolis Posted October 30, 2008 Report Share Posted October 30, 2008 You sig is pretty funny.I agree. You think you will get all this stuff at that price? lol Quote Link to comment Share on other sites More sharing options...
Daveee Posted October 30, 2008 Author Report Share Posted October 30, 2008 I agree. You think you will get all this stuff at that price? lolYes.. There is a few people in "For Sale" selling such stuff at them prices but are not active much or have allready sold them.And it's allready been stated what size Bb it is Just close this now.

Muel Posted October 30, 2008 Report Share Posted October 30, 2008 (edited) There is no way you will get that stuff at those prices, the freewheel you're looking at £15-£20 posted, the cranks £35-40, the booster £15-£20.It might be a 122.5mm, but it all depends on what cranks you have, which you havn't posted yet. Anyway, seeing as you want a set of Tensiles, I assume you're going ISIS, so as long as you get a long ISIS BB then you'll be fine.EDIT: In fact, it doesn't need to be that long, my brother had tensile cranks with a tensile freewheel, and it had loads of clearance, you could probably get away with a 122.5 ISIS bb.

Captain Scarlet Posted October 30, 2008 Report Share Posted October 30, 2008 Was the BB from a recent Onza bike?If it was from a T-Pro or higher spec then they all come with front freewheel as standard, the newer models being Tensile freewheel fitted so you probably won't have much of a problem.As for the whole, "Screw square taper!" business, if your strapped for cash, stick with square taper, I'm still running that after 2 years of trials.I do go through BB's a lot more than most trials bikers but its easier to afford £10 a time rather than £40.

But i've never had a problem before, i just switched as riding is bigger now and i've read/ heard various stories. But i don't think i'd still have any problem running Square Taper these days either. Besides as long as you maintain the bike... Quote Link to comment Share on other sites More sharing options...

NVWOCI WVS Posted November 1, 2008 Report Share Posted November 1, 2008 (edited) with a 68mm bottom bracket, you can get away with running a 118mm bottom bracket with muscleman cranks and a tensile freewheel with no bashring and have a good few mm clearence. abviously, with a 73mm shell, you're going to want an axle around 10mm longer.edit: I have some 175mm tensiles you can buy for £35 plus postage?

Mark W Posted November 1, 2008 Report Share Posted November 1, 2008 The issue with square taper cranks though is that it depends how worn the tapers on your cranks are. I had a set of Musclemen that 'cos I he-maned my cranks on all the time (Doing the bolt up as tight as I could), it meant even with a 128mm spindle I could barely get a freewheel to clear 'cos they sat a lot further up on the tapers. Seems to be a problem a few people have on here, so it's not always as clearcut with taper as it is with ISIS. Quote Link to comment Share on other sites More sharing options...
