Chris Davies added another arm blasting link to the Cromlech boulders when he extended his own problem Diesel Power by starting sitting at the base of Roadside Arete. The original line is regarded as solid V11/Font 8a; the extra pump dealt by the approach along the slopey ramp of Cave Route jacks the overall grade up to V12/Font 8a+.

The full link coming right across the roadside face remains as an obvious challenge for the uber fit.
