Mr SalinasPerfect for my deda cockpit. Thank you
Mr LockwoodThis was recommended to me by a bike fitter. It’s made a big difference to my riding position. Very pleased with the product, price & service received.
Mr KennedyReplaced like for like due to accident.Great looking and quality stem for the price. Ease of ordering and delivery. Purchased seat post to match. Graphics look great and stem shape looks and feels more than what it’s actually worth.
RjWorks well. Exactly what I needed. Light enough. Thanks!
Mr FrostNice stem for the price and looks great
maxDoes what it says on the tin! good quality and has helped my GF shorten her stem to reduce some elbow pain she was receiving.
DanPSo impressed with this stem I purchased it in the black on black for my other bike
MichaelNot one to get excited about a stem but looks nice :-) and great price
Mr PhitidisNice squarish shape and great finish, stiff and sturdy. Excellent value, and flawless service and delivery from Merlin.
Mr NAQUIDINPremium looks with minimal pricing. Stack height is a tad shorter than other stems, so might have to play around with your spacers.
Mrs DankováI 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 InceraExcelent craftmanship, perfect fit.
Mr HaileyPerfect replacement for my current 100mm Deda stem, better ride position and no more lower back pain and cyclist palsy on longer rides!
Mr KielyExcellent item, looks and feels more expensive than it was - very pleased
MatthewUsing this on the CX bike. Good solid stem at a good price
Mr BI'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 SpencerNot 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
GillespieExcellent 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.
BouVery 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...
