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


I have a czar street from 2013 frame and i want to know if this BB fits my frame.

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


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
