Dating campy components
Shimano works on four year product cycles, and the R9100 series comes with a reinvented aesthetic which features sharper edges and an asymmetic crank arm that is designed to lower the weight and offer better shifting.

If you’re buying a bike, then, after the frame, the groupset is the second thing that you should look at, and is a key determining factor in working out whether the bike in front of you offers good value for money or not.
There are three main manufacturers of groupsets and bike components.
Retailers create their own RRPs, based upon the cost of individual components, so listed prices will vary.
The newest version of Shimano’s top end groupset is the Dura-Ace R9100 series.
Disc brake iterations – R8020 (mechanical) and R8070 (di2) – use Ice technologies Freeza properties to reduce heat build up and the shifters are slimmer than former models.
That means the shifters, brake levers, front and rear brake calipers, front and rear derailleurs, crankset, bottom bracket, chain, and cassette.
There’s now dedicated 105 R7000 hydraulic disc brakes, which are identical to Ultegra’s R8020 versions.

Shimano is the largest and best known, while the other two of the “big three” are Campagnolo and SRAM.
All three manufacturers offer a range of groupsets at competing price points.
