The simplicity of the Gravel SL Pro’s name belies the true expanse of Ribble’s drop-bar mixed-terrain range. Two platforms with very different geometries are offered - and each of those is available in no fewer than four different frame materials, with each model being subtly different itself.
The ‘Gravel’ I tested here is the burlier and more rugged platform, prioritizing stability and the ability to tackle gnarlier terrain. The other platform is the CGR - which stands for Cyclocross, Gravel, Road - and was one of the progenitors for what are now known as ‘all-road’ bikes.
