Stan's NoTubes ZTR Alpha 340 - Tubeless Road and Cyclocross

Exceedingly smooth, extraordinarily fast and unquestionably the next step forward in performance. The Alpha 340 represents the first implementaion of Bead Socket Technology (BST) for the road and cyclocross market. The short sidewall and wide inside rim cavity allow for lower tyre pressure while maintaining a firm tyre feel and a more compliant ride quality.
The low weight and semi-aero profile of the Alpha 340 make for a fast accelerating, stiff and strong wheel built to meet the needs of every rider.

Bead Socket Technology

A patented design feature created to mimic the tyre bead shape and securely retain the bead for a tighter tubeless seal The inner rim shape allows the rim to be taped air tight for tubeless use with sealant, or use with your favourite clincher and tube.
Fully tubeless compatible with the 21mm yellow tape and Alpha road tubeless valve stem.


Weight - 350g

Please note, unlike with MTB tubeless conversions, specific Road Tubeless tyres are required for road tubeless, designed with carbon beads that will not stretch and cause catastrophic blowouts.
