The S2 is the best of the steel models for 2021 and the only single chainring model in the lineup, although all of the GRX equipped bikes can be easily converted to a 1x setup.

\n

The S2 frame is built from Reynold's acclaimed 631 Air-Hardened steel tubing, a big step up in ride quality from seamed chromoly and anything aluminum.

\n

Equipped with the GRX 600 group in a 11 speed build featuring a 40 tooth chainring GRX 1x crankset and an 11-42 cassette in rear.

\n

The resulting lowest gear is less than a 1-1 ratio, which is low. You can climb almost anything even though it has the simpler drivetrain setup.

\n

And if the frame wasn't enough to entice you, for 2021 the wheels have been upgraded to lighter, stronger and faster Stans Crest S1 tubeless built on Bear Paws sealed cartridge bearing hubs.

\n

This frame, with these parts, and these wheels, at this price,
is a... steal.
