Superstar ISIS bottom bracket review£29.95

Durable upgrade

BikeRadar score4/5

Superstar are generally known for cheap and cheerful componentry, but this ISIS bottom bracket is both cheap and impressively long lasting.

Most original ISIS units use skinny cartridge bearings squeezed between the larger splined axle and the shell, which meant super short lifespans.

The Superstar uses larger diameter bearings running on surfaces machined into the axles and shell, plus massive lip seals on the outside.

As a result we haven’t had a single squeak or other issue with these despite months of singlespeed abuse and they're still spinning silky smooth.

There are loads of great ISIS cranks in bargain bins too, so getting a complete bargain crank system should be easy.

Guy started filling his brain with cycle stats and steaming up bike shop windows back in 1980. He worked the other side of those windows from '89 while getting a degree in “describing broken things covered in mud" (archaeology). Dug historical holes in the ground through the early '90s, then became a pro bike tester in '97. Guy has ridden thousands of bikes and even more components the world over since then and can remember them all in vivid, haunting detail. Can't remember where the car keys are, though.
