Worked great. Looks clean. Good fit for my BMC.
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.

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

Perfect for my titanium di2 bike build
Perfect for my titanium di2 bike build. Frame was setup for internal cabling but no grommets. These do the trick .They're very tight but that should keep the grime out of the frame.

Not sure why I bought these
Not sure why I bought these...I don't have a Di2 bike. I think I accidentally clicked buy but they are true shimano parts and will work great if you need this part. If you find you need some I would be happy to hook you up with mine cause I won't use them.
