Seeing as the january sales have presented me with the bargins i don't need
and that i've choosen to take the more you spend the more you save attitude i'm looking in to a new bottom bracket and crankset. Raceface turbine cranks, both square taper and ISIS are down to 50 quid (http://www.chainreactioncycles.com/M...spx?ModelID=52) . I've only ever used standard shimano square taper in the past so my practical knowledge of any splined system is nil, however i've read that ISIS bottom brackets , due to there oversized spindle taking up more room, use smaller ball bearings which are prone to loosening, collapse and being completely ground to dust. How much of a concern do you folks find this, any experience? The crank brother sale spiel boasts 2 rows of driveside ball bearings for there splined bottom brackets; is this standard to all ISIS bottom bracket and if not does it realistically make these a better choice than one without (FSA perhaps)? Lastly, is the ISIS system that much stiffer than all tapered BB's? This one for example: http://www.chainreactioncycles.com/M...px?ModelID=676 Thanks for your views. |

They come loose, bearings are utter ****e, and the longevity is extremely short compared to a square taper cartridge. I'd stick with square, or if stiffness is an issue, go for Octalink. |

Reasonable enough mind as i'm 200+ lb rider, and i'm sure this upgrade would give better transfer than my current, but excellent value for money, deore setup. What would you suggest now? |

So octalink doesn't suffer the same problems? the axel/spindle seems as large as the ISIS and presumably the bearings are of similar size? |

What would you suggest now? i'm a ~205# and i love octalink - it's definitely stiffer. i noticed it immediately i climbed my first hill on my first octalink crank set, and i noticed it again recently when i built a cross frame with a square taper. the cranks were awful. went back to octalink again - much stiffer. |

So octalink doesn't suffer the same problems? no, bearings on the cartridge versions are pretty much indestructible. the axel/spindle seems as large as the ISIS and presumably the bearings are of similar size? shimano use roller bearings. |

My experience is simply word of mouth by local riders. Listen to Andrew. :P Personally I'm a square taper man, through and through. |
