aannnnnndddd in the Red corner.....
Ive gone back to Square Taper.
Ive ridden 4 different external bearing systems (Truvativ, Race Face, Shimano XT and Aerozine) and respective external BBs and apart from the one on the Pompino that doesnt get taken off road (Truvativ) I've got no faith in them whatsoever. Shite sealing means rubbish life expectancy of the bearings. Great design for dry dust and sun, just not the solution in the UK.
Sourced a NOS UN72 BB to put an old set of XT cranks on. Will still be going strong come the Rapture.
Sure they're not as stiff as Hollowtec cast arms and drawn axles, but frankly for the difference in pedal feel Id choose bearing life any day. As for strenght, well Ive never broken a SQT axle, and I dont know anyone else who has riding XC or godforbid even "All Mountain".
