DVO Topaz rear shock £459

Silky-smooth sensitivity gives great traction and comfort for all but the hardest of riders

During back-to-back testing, the Topaz impressed us with its low breakaway force. Thanks to a very large negative spring chamber (similar to RockShox’s DebonAir set-up) and a low-friction, bladder-sealed damper, it offers superb sensitivity at the start of the stroke and soaks up small bumps noticeably better than the benchmark RockShox Monarch Plus. Clip-in volume spacers make it easy to dial in progression too. We had to use all five provided to get the required ramp-up on our Transition Patrol test bike though, and hard riders with more linear bikes will need even more.

Digressive damping means the Topaz is very active over square-edged hits but lacks support at times, particularly in ‘open’ mode. The intermediate compression setting is great for pedal-and-pump descents though, and the firmest restricts bob yet still allows the shock to open up nicely when you hit a bump – ideal for techy climbs.

Despite the reservoir’s ‘cooling fins’, heat did affect rebound speed towards the end of long runs, but no more than on most of the Topaz’s peers. We’d like more spacers in the box, and hard riders could do with firmer damping options, but the excellent tracking sensitivity offers superb performance for most. Seb www.silverfish-uk.com
