Mr NAQUIDIN Premium looks with minimal pricing. Stack height is a tad shorter than other stems, so might have to play around with your spacers.
Mrs Danková I bought the same stem as I've had before, just 10mm shorter- and it has done a trick- I wanted to ride in a less stretched position. Good stem for a good price.
Mr Brewer Incera Excelent craftmanship, perfect fit.
Mr Hailey Perfect replacement for my current 100mm Deda stem, better ride position and no more lower back pain and cyclist palsy on longer rides!
Mr Kiely Excellent item, looks and feels more expensive than it was - very pleased
Matthew Using this on the CX bike. Good solid stem at a good price
Mr B I've been a fan of the previous model Zero 1 BOB stem, for its looks/performance vs price, paired with Deda Rhm02 bars, so I figured I give the new model a go when I needed a 120mm for a new bike. I like the new design- a little heavy maybe 156g for a 120mm, but Deda really stepped up the stealth looks for the BOB version including black bolts and faceplate. The new acorn crosssection compliments my bikes tube shapes beautifully. Note that the new version is now -8/82 deg angle and the clamp height is a low profile 36mm instead of the usual 40mm so you may have to play with your spacer stack.
Mr Spencer Not particularly light if that's what you're after, but a good quality product that looks great and does the job it was made for
Gillespie Excellent product but beware the description. It says it is an 84 degree but actually has 82 degree printed on the stem body. Still happy with the item.
Bou Very nice looking stem, the decals are quite understated compared to many other stems and the matte black finish looks great too. Not the lightest stem but difference with much more expensive stems is in the order of grams...
