Frame: The bike equivalent of a mod suit

The main frame triangle is UK-designed Reynolds 520 steel with a clean traditional look under the metallic brown paintwork. Details such as the reinforced head tube, gussetted down tube and rear facing dropouts with tension screws are well executed. Singlespeed-only mounts mean no untidy empty cable slots.

Kit selection is a mixture of proven favourites and own-brand components. The long double-butted chromoly rigid fork makes this bike a steep learning curve but keeps it light, lively and low maintenance. It's long enough to swap for suspension without altering steering too.

Shimano brakes, 1/8in chain and freewheel give proven reliability and the Continental Mountain Kings are great all-round tyres. 26in wheels mean a far broader range of upgrade options for tyres, wheels and forks.
