SHIMANO Ultegra Di2 Grommets One Color, 6Mm Circle

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.

Matches all bikes drilled with di2 holes. Super easy way to keep water out of the frame. Supple enough to go into the hole, but hard enough to stay in after they are placed, and they seal around the frame and di2 cable with eaise.

Did exactly what was expected for much less.

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

Work fantastic in my Bycicles

I only needed two. They fit perfectly.

Good

It's a grommet. It works as it should, keeps dirt and water out and it also holds the cable snugly. Simple design, simple function, works as it should.
