Reviews over the

Shimano Y1RL98100 XT M8000

The leaf bolts on my Shimano 105 R5800 were so oxidised (I think from winter cycling with salt) that I damaged the thread when unscrewing them. In 2 of the 4 bolts, the thread was so broken that the bolt could no longer be tightened. There is 13 mm thread in a 105 R5800 outer blade, so these 11 mm bolts fit easily. The original bolts are 8.5 mm long.

Pros & Cons

It may be said again: at Mantel you almost never miss when you need a part. These bolts have a white mounting paste, takes a lot of force to fully tighten.

Pros & Cons

At first I doubted it was the right one, but it fit exactly!
