  • Very well built!
Color: 25.4 x 110mm
I used this to create a shorter gooseneck for the back rider on my tandem bike. The stem is very sturdy, angle was adjustable and it offered the ideal length.

  • Great item, low cost
Color: 31.8 x 110mm
Fit and function are excellent. Adjustability is a nice feature. Helps out a great deal for “us older riders”.

  • the adjustable stem did raise the bar and shorten the reach.
Color: 31.8 x 90mm
the design does allow the bar to be raised to optional heights which also changes the reach for the rider. The only issue was the small amount of looseness between the two halves.

  • Great choice
I like how sturdy the product is. Manufactured wit attention to detail. Very readable markings and easy to adjust. Does not come with installation tools. I would definitely purchase this product again.

  • good product but it creaks
Color: 31.8 x 110mm
Product arrived on time and well packaged. Installation was easy. However it makes creaking noise when pressure is applied to ether side of handlebar. it seems secure but mildly worrisome that a future point it might break. I have tried multiple degree and still makes the noise. Seller feed back would be appreciated. ... show more

  • Fits Canyon bikes
Color: 31.8 x 90mm
This is exactly what I was looking for- raise the handle bar by desired inches for me about 5. I got stem 31.8 and length 90 mm. Originally I hit the button for the 25.4 stem. Obviously it did not fit. If any one desires higher handle bar positions look for 110mm and higher.
