Suntour SF7-Rux S review£179.99

Reasonable longer travel performance for the price, but worryingly leaky

BikeRadar score3/5Find prices on Bicycle Blue Book

Suntour make forks for a bunch of people, including Marzocchi, so their own-brand product is well worth a look. 

The Rux is longer than other jump forks here and uses a QR axle but still steers and holds a line through the berms. 

The actual stroke performance isn’t bad either. There’s a bit of clunk at either end but no obvious spikes or cavitation. 

There’s a reasonable range of rebound control and you can boost the spring rate with the supplementary air spring.

We are concerned by the fact that our sample came in a box already soaked in fork oil and continued to weep vital fluids throughout testing though.

You get a familiar hose clip on the back to keep things tidy.

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.
