Square tapper replacement bottom bracket - advice, pls.

wrote: Actually, Shimano still makes loads of square-taper cranks and BB units; far more than they make (in raw numbers) of all other types, in fact. There is no danger that they will stop doing so, either. Wasn't aware of that. That's because the commodity-level (Alivio and cheaper) cranks are what is used on the vast majority of bikes made, not the performance-level stuff. Other than a few grams heavier, is n Alivio square tapper hub any worst than a Deore one? In addition, the Octalink is apparently being phased out as Hollowtech II filters down to the lower-priced performance groups. I would bet that the Octalink vanishes and becomes an unpleasant memory long before Shimano contemplates halting thought Hollowtech II had just to do with how cranks are made, not b. brackets... regards, jbr |

99% of the bikes being sold in the world use square taper BBs. This has
been the case now for 50 years. In 10 years it will still probably be the case, and "standards" such as ISIS and Octalink will have come and gone. Interetsing view: what makes you think that Isis and octalink won't last long? Heavier? depends on how much you want to pay. A Campagnolo Record BB comes in at 190 grams. Titanium spindle models have been made at less than 150 grams. The square taper design does not inherently mean that it has to be heavier. My point was, assuming I could not get a good spec square tapper hub, only entry level ones. Glad to know I won't need to worry about loosing my cranks - I accept brakes pads as a consumable, but not cranks :-P thank you, jbr |

The differences that matter most to me are in the ramping and pinning features, and precision of tooth formation of the sprockets. The I was just refering to the diferences of b.brackets. Would an Alivio bb roll any worse than, say, a UN-7x bb?? |
