Genesis Datum 30 (2016) Size Medium (modified groupset)

Purchased in May 2016, this bike has had very little use and is in excellent condition. I bought a new Trek Domane SLR 6 Disc in the spring and immediately swapped over the front mech, rear mech and shifters. The Genesis therefore has mechanical shifting and not DI2 as supplied. However, since the swap the Genesis has probably only covered 20 miles, thus these components are effectively brand new. In my opinion a bike like the Datum, is better suited to mechanical shifting.

The Datum has been one of roadcc’s favourite all-rounder bikes for some time and was bike of the year in 2016. It fulfils the role of comfortable road/endurance bike and gravel bike taking wide tyres and having fixings for mudguards. It makes a brilliant winter all-rounder bike.
