Bruce Posted January 2, 2007 Report Share Posted January 2, 2007 I just got myself a Onza Limey frame. Spent most of today building the frame up and it looks lush. Just put in my BB and went to put the cranks on.....only to find that the cranks are too long and full on hit the slave cylinders on my rear magura! I really need some help/advice on what to do. I dont have the money to buy a new set of shorter cranks, and i really dont want to have to do this as ive only just bought the cranks. The BB is the longest ISIS one i could find (118mm i think)What can i do?!?Thanks for any help guys Bruce.ps. The cranks are 175 Tensile Urban Ledgends by the way. Dont know if anyone would be interested in a swap or something? Quote Link to comment Share on other sites More sharing options...
manuel Posted January 2, 2007 Report Share Posted January 2, 2007 get a 128 isis bb or depending on your pad rim combo you might be able to remove some pad material and push the slaves further in.128 isis available from tarty, crc, select... all over the show Quote Link to comment Share on other sites More sharing options...
Mark W Posted January 2, 2007 Report Share Posted January 2, 2007 Hey Bruce,You can get ISIS BB's up to some ridiculous number now, but the FSA Platinum Pro DH BB is a pretty decent one to aim for. They come in 68x128 too, which is what you need. If you point your broswer in the direction of Wiggle, they had a sale on on Truvativ Gigapipe DH ISIS BBs too, which are generally reguarded as having a stronger spindle. Think they're £35 or so? Either way, go for a 68x128. If they don't have them, try Tarty or anyone else who deals with Echo/TryAll, as they do BBs too.EDIT: Dammit, Rowan!

Bruce Posted January 2, 2007 Author Report Share Posted January 2, 2007 Thanks guys! That sounds like the solution. Are you 100% sure this will work? I just wnat to be sure before i go buy one and then find out it still hits.Im running heatsink snowy pads at the moment on a try rim which makes the cylinders stick out quite far. Would that make much difference? Quote Link to comment Share on other sites More sharing options...

Would that make much difference?have a quick measure of how much extra clearance you need.... i mean - is it no where near clearing or quite close ? would the extra 5 mm each side be enough ? if you have new pads then you can lose a couple of mm each side from pads so youve got a max of 7mm extra clearance if you get a 128 isis ... time to get the ruler out i would reckon.

Mark W Posted January 2, 2007 Report Share Posted January 2, 2007 I'm almost certain a 128 BB will work. I know people who run that setup, and I have a feeling Onza even recommend that length. Either way, it'll give you the clearance you need. If they still just clip, you may have to trim off a bit of pad material, but I doubt it'd come to that Quote Link to comment Share on other sites More sharing options...
Bessell Posted January 2, 2007 Report Share Posted January 2, 2007 lol awwww mine use to do that bless her R.I.P limey Quote Link to comment Share on other sites More sharing options...
Bruce Posted January 2, 2007 Author Report Share Posted January 2, 2007 Its hitting the cylinder by about 2-3mm at the moment. I will go have a measure in a second and then post what i find.Finding it hard to track down a 128x68 BB though... Anyone know anywhere that has them in stock? i have a maximum of 40quid to spend.

Mark W Posted January 2, 2007 Report Share Posted January 2, 2007 I have a feeling rubber may be easier to trim a bit off rather than metal though? Quote Link to comment Share on other sites More sharing options...

Tomm Posted January 2, 2007 Report Share Posted January 2, 2007 Finding it hard to track down a 128x68 BB though... Anyone know anywhere that has them in stock?You don't need to get 68 mm, in fact I'm not sure you can even get 68mm any more. Nowadays BBs all come as 73mm with spacers for different frames if you need them. So just get anything, as long as it's 128 Quote Link to comment Share on other sites More sharing options...
Bruce Posted January 2, 2007 Author Report Share Posted January 2, 2007 (edited) Just got some picks of the promblem. sorry if they are a bit crappy.^ This is how far the crank can go on before the arm actaully hits the cylinder.^ This is the clearance i get from the cylinder with the spacing shown in the pic above.So far im thinking im gonna have to go for the Echo ISIS one one Tarty and have to borrow some money or something.You don't need to get 68 mm, in fact I'm not sure you can even get 68mm any more.

Is this is correct it could save for a bit of money that i dont have... Edited January 2, 2007 by Bruce Quote Link to comment Share on other sites More sharing options...
Josh Greenan!!!!!!!!!! Posted January 2, 2007 Report Share Posted January 2, 2007 A longer bottom bracket will defo sort you out. 128mm. Quote Link to comment Share on other sites More sharing options...
Mark W Posted January 2, 2007 Report Share Posted January 2, 2007 Tomm's correct, in that they're all 73mm, but you need to make sure you get a 73->68mm spacer. It's basically a 2.5mm thick metal spacer that goes around the BB unit, and means it's properly centred in your frame. But that's it. Go ahead and order whatever you want, although personally I'd steer clear of the Echo BBs, just 'cos everyone seems to have problems with them...

Bruce Posted January 2, 2007 Author Report Share Posted January 2, 2007 (edited) ok so these look like my only options:Truvativ Giga Pipe £35or...SKF BFR-300 £43Which should i go for? Any one used either of them? The SKF one looks and sounds better. Both of them need a Shimano BB tool (which i dont have...). guess im gonna have to borrow some money Edited January 2, 2007 by Bruce Quote Link to comment Share on other sites More sharing options...
Mark W Posted January 2, 2007 Report Share Posted January 2, 2007 SKF for sure. Totally forgot they even existed Quote Link to comment Share on other sites More sharing options...
craigjames Posted January 2, 2007 Report Share Posted January 2, 2007 defo get the skf bb, had mine for a few months now, its damn smooth and feels really solid. plus it comes in a really cool packaging! but on a serious note it does feel fantastic quality, but has strange size crank bolts.craig Quote Link to comment Share on other sites More sharing options...
Bruce Posted January 3, 2007 Author Report Share Posted January 3, 2007 I rang up Tarty this morning and spoke to Dave and ended up going for the new Echo ISIS one. Probably would have gone for the SKF one but i would have had to buy a new tool to put it on as well as some more bolts, so i went for the Echo as i can fit it as soon as i get it...and then hopefully (fingers crossed!!!) everything will be ok and i'll be able to ride!Apparently the Echo BBs are the new ones and much better quality. Tarty havent had any problems with them so thats good enough for me.I'll let you know how i get one.Thanks for all the help guys Bruce.

hugh_b Posted February 22, 2007 Report Share Posted February 22, 2007 mine nearly touches on my new adamant with the tensile 175mm cranks, there's about a 1/2 mm clearance. Everything is new on it. So as the cranks wear in do you think i will end up tightening the crank bolt and the cranks hitting the magura???? I have a try-all bb in mine, not sure what size as i just asked tartys for a try-all bb as they new what frame/parts i had etc. cheers-Hugh Quote Link to comment Share on other sites More sharing options...
