Wheels Manufacturing Handlebar Shims 25.4/31.8mm Black

Haven't had any issues so far though this is for use on a bike that's just cruising around the neighborhood. It doesn't go offroad.;

These spacers did the trick so i could mount an old school bar/cargo rack combo on a much newer bicycle. No slippage at all even when loaded. Well machined. Big thumbs up.;

My bars were droopy and totally unsafe. I was like "what will I do Order new ones then what would I do with these? and then I found it ah ha the perfect solution to my erectile barfunction!" They were just what I needed and she likes then too!;

This product fits like a glove. However there is a couple of problems. 1) not easily installed. Hard to keep the two shims handlebars and handlebar clamps lined up. 2) I could not get the handlebar from moving from heavy torque. It works great for street riding. However I wouldn't use it for any major offroading.;

Nicely made but the tapered ends makes them not engage the stem surface fully. They need to be about 1 cm wider. Tried 3 different stems with the same results.;
