Arcade Bottom Bracket

1 comment

Hey friends- Just picked up a new to me Arcade. Anyone know which BB fits this bike? Has a Profile BB on there now, but I don't know what size to replace with. Tarty has the BB on order and wanted to know if another option was available. Thanks all.

I'm pretty sure this is just a standard BSA setup. Meaning English thread. I'm not sure if it's 68 or 73, but most BBs work with both. Profile is specific to BB shell width I guess (looking at their website).


Specififically the BB you want should be found here: https://www.profileracing.com/product/euro-externaloutboard-bottom-bracket/. You can just measure the BB shell width and the crank spindle diameter (someone else may have more knowledge on Profile cranks than i do).


Why do you want to replace it? If the cups are still OK, I would just get new bearings. Just look up the number on the bearing seal/sheild. Or measure it (37x19 or 22 I believe).


Other options:

...Might work, limited information: http://www.chainreactioncycles.com/us/en/snafu-spanish-bottom-bracket/rp-prod160429

...Will work, but needs to be found at another site: http://www.chainreactioncycles.com/us/en/odyssey-euro-bottom-bracket/rp-prod51865

  • Wondering if anyone has researched and or successfully converted some sort of non trials mtb 26" frame to a streety trials bike. Something with a long-ish top tube, 0drop bb or so, short stays, low front end like 60-80mm fork and rear disc.
  • I purchased a heatsink tensioner for my Hex, replacing the Trialtech two wheeled tensioner I have been using for years. I now have more chain than I would like hanging down. I am a half link away from being able to shorten any further and would like to use a half link. This is where it gets confusing, I have never done this before and have read on every chain description on Tartybikes that the split link that comes with every chain sold is not recommended for trials use. There are no alternatives given. I have read that people just push a link pin out enough to remove the required links and push the partially removed pin back in. This makes me uncomfortable. If I was to use a half link I would have to do this twice or, I would have to use two split links which is not recommended for trials use by Tartybikes to put the chain together. Both options sound sketchy to me. Can someone with experiential knowledge and experience please explain how I can use a half link without compromising the chains integrity so I won't worry about my chain snapping on every drop?! Split link image provided for those who may not know what it is.
  • I have the clean t13 v2 brake lever with echo calipers. I can't get the pistons to retract consistently. I've bled them several times, lubed and exercised the pistons but still can't get them to work right. Has anyone else had this issue? Thanks for the help!
