Underwhelming new hoops

SRAM X9 hubs are a new addition to the range. This wheelset teams them with Alex’s mid-width rims to make a cheap, but rather fragile result.

The Alex TD17 rims are a regular sight on complete bikes, but pin-jointed (rather than welded) construction and lower grade materials make them prone to buckling and bending if ridden hard.

Thirty-two double-butted spokes either end work hard to make them feel okay on the trail, but occasionally slow, clunky freehub pick-up and relatively high weight dulls their responsiveness.

We’ve had no issues so far, but surface grease on the freehub bearing face contaminates quickly, even in dry conditions. They only come in quick-release axle compatible versions so far too.

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.
