We said we’d be testing a chromoly Crank Bros Cobalt bottom bracket back when we tested the Cobalt crank. Unlike the titanium bracket the chromoly axle is significantly stiffer and in our opinion works better with the crankset, maximising the two-piece construction, plus the weight saving (around 50g) you get with titanium wasn’t really significant or worth the extra £100. Long term reliability with ISIS bottom brackets always crops up, which is why the Cobalt comes with a five-year warranty and also why we’ll be putting some serious mileage on this unit before an update.
