Yeah, why the square?
Out dated, not as durable as ISIS.
Square taper has larger bearings and greater durability.
snapping BB spindles for one, rounding out the tapers from normal use. Not as stiff, tendency to loosen up over time. They have been surpassed by splined cranks in every way.
In bearing life maybe, not spindle durability that is for sure.
Isis -- snapped spindles, rounding out of the crank arms, coming loose, crappy bearings.
wumpus, you're fast.
here's a thread about tapered goods if anyone is curious.
I like ISIS just fine.
ISIS has given me no problems.
Square taper on the other hand....
I've broken 3 square-taper BB's in the last couple years of riding.
broke 3 riding XC?
You must live in Bizarro world. The only problems I've encountered with ISIS were bearing life.
I've seen square tapers skewer people too many times to ever ride that stuff again.
Well, I pedaled up the hill before I did the drops...
Funny stuff! I just got rid of some 4 year old square taper North Shores. In 10 years of racing DH (225# expert) I only broke 3 spindles. 2 were Shimano UN70, one was a UN50. I only replaced them b/c I wasn't sure how much longer they would last and knew that they would go at the worst possible time. Threw on a set of Hone's.
I didn't think you could still find a square BB/crankset. The isis bottom bracket is pretty standard across the board these days. Even my BMX race bike came stock with an isis BB. Come to think of it, I can't remember the last time I had a bike with a squared BB. Either way, if you want to run one, it's all good.
