Heart of an upgrade.
Bought this to update one of my classic bikes. One of four items needed to perform the first upgrade of this bike in 30 years. As you would imagine, it might not have been too easy to upgrade such a vintage bike. But starting with this part the rest was possible. All dimensions were perfect. Can't imagine what others expect this part to be or do any better.

Great Part
I used this to raise the bars on an older road bike with a threaded stem. Unlike most of these adapters, this one is long enough to allow the bars to be positioned at a comfortable height. Now, I ride my older bike often when it used to hang in the basement all the time because the bars were way too low.

Great adapter when you need a little more length
I replaced my Cinelli quill stem and bar with a one-piece carbon bar & Stem to gain the comfort of the flat top of the bar. Most Quill adapters are too short to put the bar in the same location. This adapter added the extra length I needed. Additionally, the design of this adapter allows the bar to be removed without loosening the adapter at all. This is a GREAT design feature.

Not The Best For Road Bikes
Jenson sent my order in multiple shipments and I got everything very quickly, unlike some other suppliers that hold your order until complete or include a surcharge for back orders. I returned this item and the process was really simple and it was promptly credited. What a great company to deal with.

PROS: Great For Adding Rise, Strong Construction

CONS: Unnecessarily Long, Heavy

BEST USES: BMX, Upgrade, Mountain Biking

Bring new life to an old bike
I've used this for 2 bikes now to allow the use of a modern stem & handlebar. Now I can change out the stem to fit different riders. If your head tube is short, you may need to trim the shaft if you want a low handle bar position. The height both times matched the height of the original quill stem which was more of a comfort fit than race fit.

Good upgrade
This was the perfect solution for upgrading my older quill stem to a newer stem design. It and the adjustable stem clamp give me more adjustments to the handlebar fit.

Helped me resurrect my old bike.
As I have aged, I needed to be more upright on my bike. Couldn't find a quill that would work with my old bike (my winter bike). This product worked. Was able to use with various stems I have purchased over the years. My 35 year old frame has been upgraded to be a great bike I use when road conditions are poor.

Used on tandem "project bike" to help fix fit and comfort. Well made, precise, just heavier than I expected.

Looks great, works great
I wanted to use modern stems on my older bike that uses a quill-type stem. This adapter looks great and works great too.

How tall is this adapter from the minimum insertion point?
Daniel on Jun 29, 2016
BEST ANSWER: According to the same product listing on another website, the "measurement from minimum insertion to top of steerer adapter is 118mm".

I have this adapter on my mid-1990s rigid MTB turned dropbar conversion commuting/touring bike, and the measurement I mentioned above seems about right.
