Strengths: LightWeaknesses: Crank arms have play right from the startBottom Line: I am reviewing the Tune "Sixpack" BB (hex taper). It is similar to the AC38 (square taper). These BBs have one fixed bearing (inner ring is fixed on the axle) and one "loose" bearing (inner ring is gliding on the axle when BB shell is tightened). Unfortunately the inner ring of the "loose" bearing did not exactly fit the axle of my "Sixpack" BB, thus there was play between the bearing and the axle - leading to remarkable crank arm play. Same story with another "Sixpack" BB, so I conclude it is a general weakness.

Strengths: Light, Durable, stiff and low maintananceWeaknesses: NoneBottom Line: This is an update of my previous post!
The Tune AC 38 BB is still going strong after one and a half years service in the Dutch mud, rain and other crap.
Took it out once to inspect but it still looked and feeled like new.
The bearings are smooth like new and very well shielded from water and debris.
I'm sure that I'm going to enjoy thes BB for many miles and years to come!

Strengths: Light, good reputation and superb finishWeaknesses: Some say price but you get what you pay for.Bottom Line: Got my AC 38 bracket direct from Tune and tried to mount it with the standart 2-pin wrench, this didn't work verry well.
Had my dealer check the tread of my frame and ordered the special W2 bottom bracket tool from Tune.
Received it today and mounting was a breeze with this tool.
The tool as 6 in stead of 2 pins and is well made, almost a shame to use.
(I think i'm going to order another one just to look at:))
Mounted the bracket with copper paste and it looks and feels perfect!
I hope this bracket will last longer than the standard Shimano crap I used before, but looking at the reputation of this bracket that shouldn't be a problem for a long time!

Strengths: One of the lightest TI bottom brackets, still built to last.Weaknesses: Bloody expensive, but none other. Maybe tune should make a splined set-up in the future.Bottom Line: If you want light, stiff enough, serviceable and long lasting, this is the BB. Read the manual (in German) and install it accordingly.

Strengths: Light
STRONG ! It has long Ti screws. I broke several Ti Spindles between the bearing and the crank, those screws go deeper in the BB spindle, making it stronger.
ColorWeaknesses: They can't be tighten with a shimano BB tool
No conterbolts, so it slowly gets loose & creaks.
Not cheap !Bottom Line: truly one of the best Ti BB. Stiffness/weight ratio excellent. Would be even better if compatible with shimano BB tool.
It creaks a bit, but I must admit trials is hard for the equipment.
Maybe I should consider to get a bombproof Shimano XT :-)
4 Chillis 'cos it's 95% perfect.
