Disc Brakes

No. Post mount fitting is used for mountain bikes and was used on gravel and cyclocross bikes a few years ago. Flat mount is now the fitting standard for gravel, road and hybrid bikes. The main difference between the two fitting mount types is that flat mount is more aesthetically pleasing and less bluky - ideal for neater, more minimalist road and gravel bike applications.

Cable operated discs offer some of the benefits of disc brakes (no rim wear and more consistant braking) and some of the benefits of using cables (lower cost levers and easier DIY maintenance). The main downside to cable discs is the lack of power and modulation compared to hydraulic systems. Hydraulic brakes are a sealed system, they offer 'fit and forget' performance without the need to replace cables, as you would on cable disc brakes.

Firstly, check brake manufacturer & model, disc brake pads differ in size and shape between models. Pads come in three types; Sintered, Organic and Semi-Metal.

Sintered Pads last the longest, but take a while to bed-in and can be noisy.

Organic Pads are quick to bed-in, less noisy, but can glaze over and don't last as long as sintered.

Semi-Metal Pads combine the best elements of sintered and organic, they can glaze over and are more expensive.
