Botom Bracket Length?


Alex Dark

Recommended Posts

Iv got an onza woodstock, tensile cranks, and an acs claw ( or similar ) freewheel.....what size bb do i need?

someone told me it'd be 'close with a 113mm' then tarty Adam told me id need a 127.5mm bb...so...does anybody know what size it needs, I cant find any b/b's that big.

I haven't checked on tarty ,because their sites down I've only looked on CRC, wiggle, supercycles, trialsman(does have a 128 but its £23 which i cant afford...) and select bikes (same as trialsman, does have one but its £45...)

Please Help!

wow! that was a long ol' time ago...

i definitely needed a 128...was bloody close even with it! does depend on the thickness of your bashring and which tensiles you have- new or old?

post a full description of what you've got and we'll see...

most cases you WILL need a 128 with ANY front freewheel setup (unless you ride mod.)

Well its these cranks: http://tinyurl.com/2msz92

Onza woodstock frame, obv

And i havent bought a front freewheel yet, but i was probably going to get an acs...if not something second hand around the £10-15 mark

The problem is not finding one, but the price! I can get a 113/18 for £15 but all the 128s seem to be around £35+ and as i only paid £20 for the cranks cant justify spending that much on a bb...... :(

Any reason why not? I'd rather spend £35 on a BB and have a working bike than £15 on a BB and have a bike that I cant use, sometimes you just have to bite the bullet, if you buy a quality BB it will last a long time.

If you buy a cheap isis bottom bracket no doubt it won't last long as bearing will go i should think. Isis bbs bearing can go pritty quickly due to the axel being so big meaning small bearing. So i would just save up bit more and buy a decent bb as if you get a cheap one no doubt youll be replaceing it cost even more.

Try a gigapipe dh bottom bracket, my is still going after 2.5 years

I broke a bb once. The bearing on the non driveside cracked. Got a new bb on warranty and I have been riding it for.. err.. two years?

fsa platinum pro dh by the way, the blue one....
