Easy to install and looks great with a new stem and handlebars.
Eric✓ Verified Purchase•September 7, 2023
Updated my son's bike with a new stem and modern handlebar. This adapter worked like a charm. Gives us more options for updating the bike's set up.
Good for the price

It's tight to install but with grease it isn't impossible, it is much easier to remove than to install.
Quality item worth having

I guess this is a three item review as these are the three items I chose to update my Trek Navigator 100 with a new wider handlebar. My son says wider bars save life's and after hitting some debris and loosing control and doing a face plant giving my self a concussion I tend to agree. All three items came with in days of ordering and they all worked well together and as anticipated. The switch over actually only took an hour including test ride and adjustments.

Perfect update to accept modern bars

Quick replacement for a quill stem, to allow a wider selection of bars in the newer 31.8mm clamp diameter. The stem in the picture is 60mm in length with a 10 degree rise, for trail riding. Upgraded on a 1999 Gary Fisher Wahoo, but will work on any 1 1/8" threaded steerer tube from that era.
Machining and finish was excellent on the product I received. Another review mentions a bad angle on the jamb nut. Could have been that one, or maybe a perception caused by the bolt angle variation until inserted. Mine is the same as every quill stem I've ever worked on though.
Also, if you've used true threadless headsets, the retaining cap in those has more of a lip to keep the spacers tight. The cap on this design is flush. Not an issue for me as the stem is the top of my stack.

Didnt Quite Fit
Thomas✓ Verified Purchase•June 16, 2023
I bought this after taking the proper measurements of my bike's old quil stem. The replacement part didn't quite fit and i had to hammer it in. I mean its in there now and its not going anywhere, but I dont think I will ever be able to get it out. Didnt quite slide in there like I was thinking it would
