Fit the exit hole for the rear derailleur wire on my BMC Teammachine perfectly. I am mixing brands and using this with for a Campagnolo EPS derailleur wire, and the diameter seems about right. BTW, you get four (and only four!) grommets, which seems a little stingy for ten bucks. But now I can ride with a clear conscience on a rainy day. Yay.
G**!
Great item

Worked as expected, it’s Shimano

Used for covering Dynamo wires in an internally routed frame. Little slit in the grommet allowed them to be easily installed. Durable Shimano grommets.

Needed a grommet to re-route my Di2 cable through the stem on my road bike and these fit the bill perfectly.
