They are high quality with tapered tops and the size marked on them in while lettering. Says high quality and attention to detail to me. So these worked very well. Bars are as stiff as a drum! ### ⭐⭐⭐⭐⭐ Does it's job perfectly, easy to install. *by on Reviewed in the United States February 21, 2018* I purchased a new stem for my commuting bike as I found my old one was just a bit too short for comfort. I didn't realize that the clamp size was too large though, so I searched around for a quick fix, and came across these. They're a simple concept, and they're incredibly easy to install. I've put around 200 miles on my bike since I got these and they have held the bars on very tightly, no issues with rotating or slipping. ### ⭐⭐⭐⭐ As pictured *by on Reviewed in the United States September 9, 2012* This is a handlebar shim, not much to go wrong here. I'm writing this review to point out that if you order FROM amazon, you get exactly the item pictured. The other reviewer should have given a negative review to the seller he purchased from, not the product itself.As for the shim... not much to say. Works as expected, I like the black color (you wouldn't notice it was there unless you really looked carefully, unlike with a silver one), and this was the cheapest one that was Prime eligible. I sort of wish one of the sides was slightly adhesive or something, would have made installation easier. It would also be awesome if they had the center point marked. That's why I gave it 4 instead of 5... it could be improved. But it works as expected once its on so no worries. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.is/products/3514288-wheels-manufacturing-25-4-31-8-handlebar-shim-1-pair](https://www.desertcart.is/products/3514288-wheels-manufacturing-25-4-31-8-handlebar-shim-1-pair) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-08-21*
