Shimano 105 BB-5500 V1 Octalink Bottom Bracket

I used this to replace an XTR bottom bracket in an older Cannondale that was once the pinnacle of the bike world, but now, like it's owner, is happy to just plonk along on the trails and take it easy. This new 105 bottom bracket is silky smooth and strong, but it does not have that teflon-coated zero resistance feel of the old XTR bracket before it wore out. While I don't expect it to be as good as the XTR or Dura-Ace versions, it is not much of a cost savings to use the 105 version. But if you can't find those higher grade options, the 105 is plenty good enough.

I ride an older litespeed with the old style tapered bb. This one is a perfect replacement without any hassles!

A little bit on the expensive side compared to similar products on other places, but Bike Tires Direct was the only place that I found it.

Not only are new BB-7700 hard to find, they require more upkeep than a casual rider may want to endure. BB-5500 is a nice replacement for bikes still using Octalink V1 cranks, and the weight and drag are negligible for anyone not racing. Get over your disdain for 105, Tubby.

I use 105 bottom brackets for my cyclocross bikes. They are reasonably priced and give good performance at a reasonable weight. Bottom brackets seldom last 2 years for a cyclocross bike. For this cost I an swap them out before they fail and still get solid performance.

Needed this for a older Ultegra Crankset I switched to a Soma Double Cross. Working great so far. Only have a couple hundred miles on it but running smooth.

Getting hard to find, but a sturdy part if you need it.
