Reviews over the

Shimano 105 R7020 Disc

Got this to upgrade an entry level gravel bike and the hydraulic disc breaks are a revelation. 105 is all the groupset most of us will ever need. The new iteration refreshes the chainset and improves the ergonomics of the previous hydraulic shifters. It’s as reliable as ever.

Pros & Cons

My first time fitting disc brakes, and it couldn't have been simpler. Hoses and lever reservoirs are supplied ready-filled: just install, cut the hoses to length and a few them into the hoods. I tried bleeding them, but it wasn't necessary: the system was already filled. Really couldn't be simpler. Perfect braking now, even in the wet. A transformation compared to caliper rim brakes.
