On the long side for Shimano Road calipers (105/Ultegra), but works in a pinch
"See review title. This will work on Shimaon road calipers, but is longer than the stock option, so the snap ring will sit several mm outside of the caliper. Not a huge deal. It still works. On the plus side, this uses a hex head (thank goodness!) instead of a slotted/flathead screwdriver, like the road calipers include by default. The top part of the original bolt (Ultegra caliper) literally broke off upon removal of the pin on my bike. Two things: 1) Put grease on those threads before installing! Mine had some corrosion, hence some force was needed, which the slotted head could not handle. 2) why doesn't Shimano use a hex head on all of these? It's a much more robust interface."
