    Bolt too short
    The roller itself seems to be ok, but the bolt that came with it was too short for my yz125. Had to go to the hardware store and buy a bolt that fit. If you just need the roller, this might be an ok purchase. But if you need the hardware, you might be disappointed.

    Roller change.
    bearing went bad in my stock roller. It was the lower one. When I was installing noticed the roller was two millimeters bigger. But I was able to simply use the bearings and spacer and fit them to my original roller as the roller itself was not bad, just the bearing. Probably my mistake for not measuring before I ordered.

    Very good value at a very good quality, I would reccomend to anyone who’s looking for a cheap chain roller.
    I would reccomend this product, it’s a good quality at a good price, seems like it will last because of an almost rubbery plastic material.

    Good cheap rollers
    Rollers seem like decent quality pieces. Had to use old bolts due to the new ones being too short.

    Not worth it
    Upper: My factory upper roller didn't have a bearing in it but spun better than this one. It felt ok when new but after 5 rides the bearings feel like garbage.

    Lower: The hardware that comes with this is universal so you have to mix and match with the stock stuff to make it fit properly. It's ok for the money, however I would recommend another brand.

    does this replace the lower chain slider on my bike? I cannot find a chain roller on my bike?
    Eric J on Feb 7, 2017
    BEST ANSWER: It fit my sons 2002 KTM 300EXC. It is located on the lower side (bottom) of the swing arm NEAR the kickstand and near the swing arm pivot bolt. Near the front sprocket . Not near the rear sprocket. Lower chain goes over (or above) it as it travels from front to rear sprockets.
    It is bolted to the inside of the frame.
    What is the dimensions (specs) of this chain roller?
    A shopper on Sep 22, 2018
    BEST ANSWER: If you look it up on Rocky Mountain it'll give you the dimension this one is a 31 mm
    Is this an 8 mm mounting screw?
    A shopper on Jan 2, 2017
    BEST ANSWER: It comes with the correct size bolt for your machine. But in most cases, it is the 8mm bolt with a 10mm head.
