DT Swiss Spline One Boost 35 review£800.00

A responsive and agile plus wheelset

BikeRadar score4.5/5

DT Swiss’s Spline family is smashing it in every category right now and these wider wheels are in a completely different league to other plus wheels we’ve tried, making them well worth the extra cost.

While the numbers are certainly good, there’s way more to the performance of these wheels than just low weight in all the right places.

Tubeless inflation is blissfully easy — the tyres are neither a fight to fit or so loose they burp under hard cornering, which is lucky as they beg you to bar-drag and drift every corner or cut hard and late well inside the comfortable arc of the other baggier wheels on test.

Straight-pull spokes in small block flanges create rock solid power delivery and braking, while they’re a joy to flick about on the trail rather than just rolling along flaccidly.

Despite their scalpel sharp turning precision they don’t punish your palms or stutter across the trail surface either. The result is a wheel that feels as accurate and responsive as a top quality 29er wheel, but with all the ragged terrain rollover and stalling speed advantages of a plus set-up.

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.
