The Toughroad is a great no-nonsense bike, I have the SLR-0 (now discontinued) and love it. The ride on the 50mm tyres is really very smooth. Frames are the same throughout the range and feature their ultra lightweight Allux-SLR aluminium and the same carbon composite forks. Mine weighs in at 10.4kg (23lbs) inc pedals - a useful weight saving if you don’t need a suspension fork. The only thing I personally don’t rate is the saddle which is not comfortable at all!

The main differences I can see (apart from the colours) is that the 2018 model has the lighter, better quality SX-2 wheel set with factory fitted tubeless tyres whilst the 2019 model has the lower spec GX28 wheelset and tubed tyres.

The 2019 also has the Alivio rear derailleur which is one level up from the 2018’s Acera, as well as slightly different model brakes and crankset which are pretty much the same specs just newer.

Personally if it were me, I would go with the 2018 model with the slightly better wheelset and a useful $100 saving.
