trialtech bb spacer (the one on the cup)


trials hoe

Recommended Posts

Right, so the tt bb's have a spacer on the drive side cup to allow them to be used as a 73mm bb if you take it off. I've looked on tarty and they don't stock them as spares and i need the spacer (to run it in a 68mm frame) is it as simple 'fix' as I'm thinking it will be?. Have had a look on crc and hope do a spacer ( http://www.chainreactioncycles.com/Models.aspx?ModelID=36416 the 2.5mm one ) that is aimed at the hollow tech bb's (or whatever they're called, I have no experience with them) and I'm pretty sure that they fit in a 68mm shell frame same as a 'normal' bb within the same threads ect.

So will the linked spacer fit/work and sort the offset to a being like a 68mm bb (like it would be with the tt spacer supplied with the bb that I don't have)?

Other wise it'll be offset towards the non-drive side of the frame, while it might not be hugely noticeable I'll know and that'll be enough to piss me off no-end.

cheers in advance :)

Its just a standard bb spacer with trialtech wrote on it. Just get a 2.5 mm spacer off crc, its the same thing

like the one I linked then.........

How du know it's not already offset and designed primary for a 68mm? :P

on tarty,

- Fits both 68mm (use spacer provided) and 73mm shell widths.

I think i have one at work, i'll find out later and PM you mate, you can just have it :)

nice (Y) free is always better than buying hahaha

I used a spacer from a cassette I'd taken apart, seems to work.

Your running your spacer to avoide the freewheel/ crank rubbing on either frame or magura aren't you ?

I'm confused why you need to use this spacer for any other reason.

I don't run any spacers with my trial tech bb

says on the bb, 73mm without the spacer 68mm with it. other wise the bb will be offset towards the non-drive side, the same as a 73mm bb in a 68mm frame.

Ah ok I see, mine is fairly old now not sure if it says that.

Personally if your chain line is ok and cranks don't rub I would do with out that spacer and have more threads of the bb cut in the frame as they are short on the trial tech cups

to be fair it'd only be a 2.5mm difference if i didn't run one and if i just wacked it in and never looked i'd never know any different, but because i do it'd do my head in and i'd convince myself that i could feel the offset if i didn't stick a spacer on. if chain line is an issue i'll swap the the tr sprocket with central teeth for one with teeth at the end of the sprocket instead.

Yea fair enough, it's all in the mind after all
