Review: Great Stem Upgrade for a Better Ride - I bought this Wake 31.8 mm bike stem to upgrade my mountain bike, and it turned out even better than I expected. It feels sturdy, well-built, and surprisingly light. Installing it was simple, and it fit right away without needing any adjustments. After using it on a few rides, I noticed the steering feels more responsive and the bike handles much better. The different color options are a nice bonus and make the bike look great. For the price, the quality is excellent. Overall, I’m very happy with this purchase and would definitely choose it again.

*by J***. on February 2, 2026*

Pretty lightweight although made of aluminum. Works for a ridstar q20 e-bike, and probably any ebike for that matter. Nice color and not cheaply made, great quality. Ignore the cheap price, you wouldn’t even know. Id still buy this if it was 30 dollars
