Cube’s 2021 line-up introduces a number of new & updated mixed-surface off-road road bikes, with the refreshed Cube SL Road an interesting look at the classic hybrid or fitness bike. Instead of detuning a mountain bike they’ve reimagined a flat bar gravel bike as the perfect way to zip around the city during the week, then still being able to hit some dirt on the weekends.

Cube continues to have a hard time figuring out where to place the new SL Road in their lineup, at one point dropping it at the bottom of their road race family, then also calling it a fitness or even urban mobility bike. But that’s probably just a testament to how versatile the bike can be. As anyone who has really latched onto the gravel bike craze of the last few years can tell you, you don’t only spend your time on gravel roads. Plenty more time is spent riding quickly on asphalt, with the occasional bit of singletrack thrown in for good measure.

Now for 2021, those people who want the versatility of a quick gravel bike, have another good multi-purpose, affordable bike option with the relaxed, upright position of a flat mountain bike bar.

SL Road – Tech details

The core of the updated Cube SL Road is a lighter weight hydroformed aluminum frame welded from double-butted heat-treated alloy tubing, but without losing the versatility. The SL Road still features full rear rack & fender mounts (and even a kickstand), but now adds flat mount disc brakes & 12mm thru-axles, too. And now the SL Road gets a light full carbon fork with fender and low-rider rack mounts, as well.

All models get spec’d with 700c x 40mm tires with plenty of clearance for a bit more – Schwalbe Little Big Ben city tires for the two cheaper builds and G-One Allround light gravel tires for the two top bikes.

Geometry-wise, the SL Road is a bit steeper than Cube’s proper gravel Nuroad family, but it still gets similarly long chainstays for stability on and off-road.

    what is the point of a 2x drivetrain on a commuter bike? entry level mtb 1x drivetrains are foolproof, cheap and have more than sufficient range

    @Evan … they are marketing this as a gravel and adventure bike not a commuter bike. I’m currently shopping for a gravel bike on which to go bike packing. I realise it’s personal preference but I wouldn’t consider a 1x drivetrain.

    Reach of the bike very short. Is it that they just put a flat bar on a grop bar frame? I’m trying to figure out how upright this bike is.
