View Full Version : which cartridge BB ?

The stock BB on my fuji track is shot. Any suggestion for a cartridge BB (under 50$ if possible) ?
Shimano or Sugino ?
Campy and Phil's are a bit pricey...
By the way, the current is 68x114, giving me an odd chainline of 47mm. So anything narrower than 114mm is already an improvement.

Thanks

I got the $11 Shimano BB. Works fine

:( I don't remember which one it is though

I have Shimano UN54 on my fixed gear and have had zero issues with it. Have put 1000's of miles on it through all weather and still spins smooth.

Another vote for Shimano. I'm pretty heavy, so it flexed around a bit, but honestly I have no idea if that's the bottom bracket, cranks, frame or any other factor, so as far as I'm concerned the BB is fine.

The bottom bracket spindle is pretty much the last thing that you could possibly flex.

I have a shimano bb on my singlespeed road bike, it works great.
I actually took this bike out the basement the other night just to ride something different, it was a blast. Now I have both the steamroller and the ss ready to go at any time.

Shimano UN54/52 are nice (only difference is the newer one has a plastic non drive side cup).

I've been using the IRD for about 4 months though and it's super smooth. Also comes in a ton of spindle lengths.

If you need a 108mm ISO spindle, I've really had a great experience with my White Industries bb. Good alternative to Phil, and only $100.

I had this same problem a while back. For my winter riding I wanted a cartridge. For anything reasonably priced, the Shimano was the way to go. Definitely heavy, as it feels like a frickin brick in your hand, but also seems pretty indestructable. I've used them twice, and although I think there are better bb's out there, for the price and depending on your function you can't really beat it.

I have the UN54 right now which works great, but I might end up switching to the Sugino 103mm eventually for chainline reasons.

The UN54 comes in a 107mm spindle which should work great. I just used one on my conversion.

i vouch for the 75s, but either are great.

I've got a UN54 on all my bikes. Never had a problem with them, even when I was 260-ish pounds. They're heavy, but at my weight, what's a few grams for the security of near indestructability?
