Can't vouch for them personally
That's what he's got currently, as he's borrowed it from me!
Gotta be said there aren't too many nice 60mm stems out there are there… Lots of 50mm's, quite a few 65's, but not many 60's… I bought that cheap 60mm stem just to check the fit, decided the length was for me, then thought I'd just buy a nicer one. To be fair, it's well made, very light (like 120g light!), seems plenty tough enough, and even looks ok. So it's not getting replaced any time soon! You can forget the old Keith Bontrager addage of "light/strong/cheap, pick two" as this stem really is all 3…
Queue a text message tomorrow of "sorry mate, I've broken your stem!" from someone… 😉
