SR Suntour Durolux RCA-TS 20QLC fork review£384.95

Budget long-travel fork

BikeRadar score1.5/5

Suntour's bargain big-hit fork is structurally tough and simple to use, but the internals aren’t up to hardcore use. The tapered steerer option keeps it up to date and the chunky lower legs give decent steering and tracking accuracy. The Qloc 20mm axle pops in and out neatly and securely once you’ve got the knack.

This fixed 160mm (6.3in) travel air-sprung option is a reasonable weight too (just under 2,400g). Within hours the fork started to show serious clunking top-end issues off drops or pulling-up on dynamic moves. Firmer compression damping settings introduce spiking rather than progressive control without stopping the harsh bottom-out, and also killing small bump traction.

After a couple of hard days it had picked up a noticeable notch. By day three it was blowing straight through its travel, even at high spring pressures. A week in, it rattles and bangs like a tractor, even on cross-country trails. The Durolux is cheaper than most big-hit single crown forks, but it’s still a lot of money for a fork that suffers so badly after a few days of serious use.

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.
