    • Ridstar
Color: Black
Very nice quality; made the handbars on the Ridstar Q20 closer, which improved comfort. The color is simple and looks awesome. Size is perfect, not too small nor big; installation was very easy, can be adjusted all around and was very versatile.

    • Solid Upgrade for Better Control and Style! 🚴♂️🔧
Color: Gold
I installed this Wake 45mm stem on my MTB and instantly noticed the difference—tighter handling, more responsive steering, and an overall better ride feel. It’s made from solid aluminum alloy, so it’s lightweight yet super sturdy. The finish looks great (I went with the black/blue combo), and the installation was quick and easy with standard tools. Whether you're upgrading your mountain bike, road bike, or BMX, this stem delivers both performance and style at a great price. Highly recommend for riders looking for more control and a cleaner cockpit! ... show more

    • Good enough for price
Color: Gold
*former bike mechanic of 6 years* Ive had this on my stock Giant Talon for a year and a half now, and it’s fine. I ride my local blue and black trails that range from moderate downhill, small jumps and drops, to techy xc stuff. My area is realllly rocky. No real issues, it’s holding up fine, but I am only 160lbs. My biggest complaint is that it’s creaky. I’ve taken it off, thoroughly cleaned, greased bolts, and reinstalled and made sure to tighten the bolts evenly and to the torque spec multiple times, but I can’t get it to stop creaking. Especially noticeable on climbs or when you put a lot of torque on the bars. It doesn’t fill me with confidence, but again, it’s been ridden fairly hard for a year and a half and hasn’t failed yet… it was only 10 bucks. If it costed more then it would get a lower score. Got the gold and it’s cool. ... show more

    • Great Stem Upgrade for a Better Ride
Color: Black
Review Image by Sindy Leal
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. ... show more

    • Works great, but remember to think about headset spacers when ordering
Color: Green
Great product for the price. Provides much more comfort from the longer stock Trek head clamp. Color works good too, about as close to the photo as can be. I regretted not getting the gold, but thats on me. One thing people should be aware of: You'll likely need an additional headset spacer to make this work. The stem clamp is shorter than most stock, and an extra spacer is needed to fill the gap and pull the headset bearings tight. ... show more
