Would this fit a ozonys v8 frame (20") with a comas freewheel (108 point one) and a jitsie bashring

Hi Oscar!
As long as you have a pair of ISIS Cranks you're planning on using with them then this BB should work fine with that frame and parts kit.


Hi will this fit a onza limey 320 2012 thanks gazz

Reply from TartyBikes

Hi Gazz - This BB will fit into your Limey frame fine, but to make sure the axle is the correct length it would be best to measure your existing BB axle. With some setups you're better off with a 122 or 122.5mm axle length, but for others the 128mm (like this BB) would be ideal. If you can check your existing BB then that should let you know whether this will work for you. Thanks, Mark


Would this fit a 2004/05 t-mag what is running a tensile freewheel and tensile crank arms n matching bash ring

Hi Josh - This should work fine with that setup. Thanks, Mark

brogan bursill

hi, would this work on a 1010 jitsie frame with echo tr cranks?

Posted by brogan bursill

Reply from TartyBikes

Hi Brogan - This should work fine with that setup as long as you have the TR cranks that use a screw-on freewheel rather than a splined one. Thanks, Mark


Hi would this BB fit my onza comp 2010

Hi Danny - This BB should fit your Onza Comp nicely. Thanks, Mark


Hi I was just wondering if you know what bottom bracket will fit a ko bikes km1 and if you sell them ?

Posted by Rory

Reply from TartyBikes

Hi Rory - thanks for your question. Any threaded bottom bracket we stock will fit, and the longer the axle used the less clearance issues you will have. A 128mm option such as this would be perfect. Hope that helps. Thanks, Flipp.


Will this fit my 2009 Onza Blade? I'm running a Tensile FF Freewheel, Echo 160mm ISIS cranks and a 74 Kingz bashring. Many Thanks

Hi Will - thanks for your question. Yes, this will fit your bike just fine. Thanks, Flipp.


will this bottom bracket work for a giant stp frame (73mm), along with try-all isis cranks, ffw and bashring? I know most folks are using frames with 68mm bb spacing, so not sure if this will work with 73mm. Any ideas?

Reply from TartyBikes

Hi Kirk - thanks for your question. This bottom bracket will work perfectly with a 73mm shell. Simply don't fit the extra washer that is supplied (this is for use with 68mm shells). Thanks, Flipp.


Will this bottom bracket fit my Inspired Element,since i am using a bashring ?

Reply from TartyBikes

Hi Sam - thanks for your question. This bottom bracket will fit your frame just fine, and it has the longest axle available so clearance will be no issue. Thanks, Flipp.

adam sadowski

is that BB be fit to my 20" onza pro 2012 or 2011

Posted by adam sadowski

Reply from TartyBikes

Hi Adam - thanks for your question. This bottom bracket will fit your frame just fine, the only problem could be your cranks. The cranks on that bike have been made in both square taper and ISIS models, so you would need to find out which you have. If the hole in the crank that the bottom bracket fits in to is a square, this will not work. If it is a circle with ten splines machined in to it, this bottom bracket will fit perfectly. I hope that helps. Thanks, Flipp.


Will it fit on my Because Simple Street 2010 frame witch have 68 mm wide?

Posted by Petras

Reply from TartyBikes

Hi Petras - It should fit absolutely fine. You will need to use the thin spacer supplied with the BB to get it to fit your BB shell correctly. Thanks, Mark

chris tabb

hi guys. will this fit my 2002 Koxx Frame? Cheers chris

Posted by chris tabb

Reply from TartyBikes

Hi Chris - I can't see any reason why not! Thanks, Mark

Henry Wingfield

Cheers, it would be the Tensile freewheel, Echo Urban bash and Echo 7075 CNC cranks

Posted by Henry Wingfield

Reply from TartyBikes

Hi Henry - In that case, I'd imagine it would work fine. Thanks, Mark


Will this fit a tensile front freewheel and an echo urban bash ring on a zoo python 07 frame?

Posted by Henry

Reply from TartyBikes

Hi - To fully mae sure that they'd fit it'd be good to know the type of cranks you're using, but generally speaking most cranks out there, with the Tensile FW and Urban bashring, should fit fine. The Race BB uses a 128mm spindle which is the most popular length in trials because of it's compatibility with almost all setups. Thanks, Mark

Brett Stollery

Hi Tarty, I was wondering if this bb will be suitable for a front freewheel with a trialtech half alloy bashguard? Thanks, Brett

Posted by Brett Stollery

Reply from TartyBikes

Hi Brett - Depending on your freewheel, it should be fine. If you have an ENO or a similar 'tabs out' style of extractor tab then it might be pretty close, but for most modern day freewheels with recessed extractor tabs it should be fine. Thanks, Mark
