DMR Zone Boost wheelset review£450.00

Tough and tubeless friendly

BikeRadar score3.5/5

These new Zone wheels are much wider and tougher than the first-generation sets and properly tubeless ready, but they’re seriously heavy as a result.

While the outer rim width is 35mm, thick walls and pronounced lips mean the internal aperture is only 28mm. As a result, they’re best matched to 55-58mm tyres, which generally equates to 2.3-2.5in, depending on brand.

They come taped and valved as standard, though, and most tyres I’ve tried on them can be inflated with a track pump and stay secure down to low pressures. The extra wall thickness means the rims are impressively dent-proof so far, which was the Achilles heel of the previous sets.

The ride feel is solidly shock-absorbing without being overly harsh

A well-tensioned build with 32 double-butted spokes and brass nipples gives plenty of failsafe strength to back up the welded rims.

The ride feel is solidly shock-absorbing without being overly harsh, and they track and hold lines and momentum confidently no matter how rowdy it gets. Pick-up from the ‘Superlight’ rear hub is firm once you’re past the (average) 10-degree freehub lag.

At 2,170g (1,020g front, 1,150g rear), my 29er wheels (650b also available) take a lot of effort to accelerate or change direction, and they’re only available with splined Center Lock rotor mounts.

Pricing is comparable to similar sets from other brands (front: £200, rear: £250), though, and you get a rim sticker sheet for personalisation.

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.
