The Alpha 340 represents the first implementation of Stan's Bead Socket Technology (BST) for the road and cyclocross market.
The short sidewalls and wide inside rim cavity allow for lower tire pressure while maintaining a firm tire feel with decreased rolling resistance and a more compliant ride quality.
The low weight and semi-aero profile of the Alpha 340 makes for a fast accelerating, stiff and strong wheel built to meet the needs of every rider.
Super-wide 17mm inside cavity
At just 350 grams the Stan's No Tubes ZTR Alpha 340 rim is the lightest road clincher rim we stock.
Many things to many different people - a lightweight climber, a super fast crit racer, a long distance trainer or anything in between.
Even though they are super lightweight they are well able to handle some abuse as well, as demonstrated by being ridden to a Masters Cyclocross World Championship just months after being introduced.
