Questions

Dimos Tsag

Hello, I would like to ask whether this bb (and the sport lite crankset) would fit a 68mm width spanish bb shell (I've got a NS holy with spanish bb 3-piece bmx cranks currently). Thank you in advance. Kind regards, Dimos

Hi Dimos!
I believe this should fit your NS Holy, but it would be worth double checking by measuring your frame first.
If you're able to measure from the bearing stop to bearing stop inside your BB shell, you would ideally need this to be 48mm to use this BB.
As it doesn't have a traditionally tube spacer arrangement like a BMX-style BB, the distance between the bearing stops has to be correct otherwise the bearings will fail fairly quickly.
If you have a 68mm width shell, the bearings are 10mm wide each so it sounds like it would be 48mm stop-to-stop, but as before, double checking would be for the best.
If the BB fits your bike, then the cranks would be no problem either.
If you need any more help with measurements/fitting, feel free to ask!

This BB would fit to the new crewkerz (Jealousy) or clean (x2) frames?

Hi Tamas - The Crewkerz and Clean frames use the BB30 size BBs, so this Spanish BB won't fit, sorry. You can only use the Crewkerz/Clean BBs in their frames. Thanks, Mark

Hi Daniel - If your Czar has their press-fit BB system (if it's from 2013 it should) then this BB would fit your frame fine. Thanks, Mark

Hi, the thing is I am trying to reduce the weight of my bike. I have an arcade frame-fork kit with the classic truvativ bottom bracket-ckranks-bashguard (the one that came with the 2013 fourplays bikes) equipment , so I was thinking change it for some trialtech sl cranks combined with a trialtech full sport ring bashguard and some trialtech sproket with 22t. I realy don't know if they all fits, and if it would be a correct bottom bracket. At last, please tell me if this change is recomendable (or other solutions). Sorry for the english, I use to talk in spanish :). Massive thanks!

Hi Raimundo - This BB wouldn't fit your Arcade, although the Sport Lite BB should. The SL cranks are still nice and strong (Flipp has been using them on his bike for a long time with no problems!) so should work well. They're not a 'normal' choice for this bike but they should be strong enough, and you will save weight. If you'd like to save some more weight (and possibly money), you could change to running an 18:13 gear ratio. We are currently running an offer where you would receive a free Trialtech Ti Twin Bashring with the SL cranks, so if you used a screw-on 18t sprocket and bought a new rear sprocket, you could downside your drivetrain - but keep the same pedal feel - and save more weight overall. Thanks, Mark
