Tom Pidcock continues to put SR Suntour's electronic system to the limit

Last year we first discovered that Tom Pidcock was testing a new electronic suspension system for SR Suntour on his camouflaged BMC Fourstroke. Something we've seen again on the bike he's racing at the Albstadt World Cup.

This is the BMC Fourstroke on which Tom Pidcock is racing in Albstadt.

Despite the fact that Pidcock hadn't raced MTB since his gold medal at the Tokyo Olympics, it only took the British rider 3 laps to get to the front on the Albstadt Short Track. Under his feet, practically the same BMC Fourstroke he raced last year.

It is surprising that the system's sensors cannot be found in plain sight. 


The set-up is the same as last season, and SR Suntour's electronic prototype continues to surprise. Both the fork and shock have no remote controls and are intelligently adjusted to lock or unlock depending on the terrain.

The shock absorber seems to have been developed for this system, when he races without electronics he uses an SR Suntour Edge.


Little is yet officially known about SR Suntour's new system, but from the pictures you can see that the level of integration is far superior to that achieved by the Fox Live Valve or the recent RockShox Flight Attendant, the two electronic systems on the market. It remains to be seen whether this integration will be universally available for all mountain bike models or will only be standard on some.

Just behind the shock absorber, you can see what looks like the system's control unit connected to a cable emerging from inside the frame.


In any case, SR Suntour may have found its way ahead of Fox and Rock Shox in the electronics field.
