I’m recently purchased the Superstar AM’s and thus far have been nothing but impressed. Delivered 2 days after order (late afternoon order) kept abreast of delivery and tracking provided, well packaged and really do look the business outof the box.
Riding wise they feel a lot stiffer than my old Crank Brothers setup, have a loud rear hub (if that’s your thing) with a good pickup, easy to set up tubeless with the right tape and vales they also sell at a good price.
My only gripe so far, was that and it could be my tyres, but they were an absolute sod to get on the rim, very tight fit and I ended up wrestling with them for a good few hours and pretty much utilised every expletive known to man!
