More comfortable riding position
I bought this stem to raise the bars on my MTB to improve my riding position. Easy to fit and robust enough for off-road trails. I am now more comfortable on the bike and having more fun.

Handlebar stem
Wanted to change riding position and take some weight off shoulders this has really helped. Good quality product quick delivery.

Seems like quality product
I have had neck surgery and now need a more relaxed riding position. Going from a standard 110 mm 6/7° to the 70 mm 35° stem has made a huge difference. The stem itself seems to be a well-made product (which met the approval of my discerning bike shop).

Low back pain eased
Bought this for my MTB. Was feeling back pain and thought it could relate to handlebars being too low vs saddle. Already had riser bar so needed another solution to maintain reach- this did the job. Even slightly too high so used single stem spacer to get a happy medium. Feels well made and solid.

Awesome
Hello. I’m 6’5” and ride a Giant Defy Advance 2 XL. I bought this stem clamp to see if it would help my riding position, as well as stopping or reducing neck & back pain without hindering performance or response to the handling of the bike. I do long rides (up to 200 miles) as well as daily commutes to work (10 miles). I bought the shorter neck stem of all available. The difference is amazing. So far dare I say the ride is so much better and comfortable. My positioning on longer rides is so much more comfortable & relaxed. There’s no fatigue on my arms or shoulders. I can still drop down into a race position and reach decent speeds. This is more evident on my commute to and from work which is quite hilly. I was experiencing sharp pain near my neck (left side in trapeze muscle) along with stiffness and soreness during and after a ride. This so far hasn’t occurred and my neck feels loads better. I do have some arthritis in my neck. The responsiveness of the bike seems to have actually improved, the handling feels far better and sharper. I’m certainly turning better, the handle bars are now more above the wheel than they were with the original stem, this has definitely improved my riding. When standing on the steep uphill climbs the ride isn’t hindered at all. Again it feels better as I’m not bent over as I was before. In short, this has been the best addition to my bike and my riding so far. I wish I’d bought this sooner.

Really great product. I ordered one but can not install due to wrong size I ordered. Quality seems top notch and finish quality is amazing. Had to return. Will order different size.

ハンドルを留める4本のネジの精度は高く均質である。 只、メス側の1か所のネジ切りの精度が低く他の3か所のように奥までねじ込めず途中で止まってしまう。 幸いハンドルを固定するまではネジが進むので実用上問題ないが人に勧めたり譲ることは出来かねる。 価格的に面倒な返品等は避けて我慢して使っている。
