Exceedingly smooth, extraordinarily fast and unquestionably the next step forward in performance. The Alpha 340 represents the first implementation of 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.
Fully tubeless compatible with the yellow tape
Brakes: Rim Brake
Tape Width: 21mm

Rated 3 out of 5 by foxy probably too light
got these built up with reynolds hubs and lazer spokes, light at 1370gms a pair BUT the rims are hard to get tyres on and some makes will not stay on! and not much stiffness either, probably ok if you are under 70kg.

Rated 5 out of 5 by Anonymous Lighter and stronger than carbon
I wanted a light set of wheels to ride over pyraneese. I build these in a sub 1400g wheelset. These were lightser than som eof the carbon options. I weigh 90kg and they got me over the frence mountains easy. tyre fit is good. great strenght and they are alloy so they brake well with out specail pads. these are so good i am planning a new build.

Rated 5 out of 5 by Anonymous Just perfect!
Actual weight for 18-hole rim is 358 gramms and 355 gramms - for 24-hole one. Machined brake surface width is 9 mm. ERD, measured according to DT Swiss spoke calculator recommendations, is 593 mm unlike 591 mm, as specified by manufacturer.

Rated 5 out of 5 by Anonymous Light and surprisingly sturdy
Summary tells the whole tale. I used these to make some "stoopid-wheels" for my track bike, but the final packaged laced with revolutions is simply a seriously light, seriously good looking and best of all, they seem to be stiff enough for my 90 kg weight. You get what you pay for: They aren't cheap, but in this case you're not choosing two out of three. (Quality-Weight-Price)
