ZTTO MTB Bicycle Rear Derailleur 11T Guide Wheel Idler Pulley Bike Riding Accessories

great gear, perforated means with the holes in the teeth. Caps are always there. Thought it might be too wide, but it fits just about right, actually perfect.

The goods arrived safely, the bearings are running great and the pulley is already installed. As an aluminum pulley, it is a bit louder than the plastic original.

They arrived a little late but they are fine.

I'm happy . Thank you .

The bearing does not rotate. Bullshit

Poor quality bearings

Good quality

Perfect !!!

Very well

Good

It's bad that there are holes in each tooth, I've already used such a sprocket, but it's good on the flat but not very reliable when working on a steep climb, for example, mine just broke teeth.

One is damaged and cannot be used for its intended purpose. The second bearing does not spin and also cannot be used for its intended purpose. Wasted money and time

The golden color turned out to be orange (there is a small gap, the quality is good.

Very good stars, I recommend
