Most bicycle caliper bolts drag against their washers during tightening, causing misalignment and frustration. absoluteBLACK solves this with bolts and washers treated with distinct PVD coatings that dramatically reduce friction—so torque is applied smoothly without shifting the caliper. The result: faster setup, precise alignment, and reliable braking performance, every time.

Colours: Rainbow or Grey
Compatibility: all Flat Mount Road calipers.
Material: cnc machined Titanium Grade 5
Finish: special PVD coating
Size (mass with washer): M5 torx T-25 / 15mm (2.0g), 22mm (2.5g), 27mm (2.8g), 32mm (3.0g), 37mm (3.4g)
In the box: 1 bolt + 1 washer

IMPORTANT: To determine the correct bolt length for your setup, please measure the bolts on your bike. Each frame and model typically requires different lengths, so we are unable to advise exact sizes. The simplest way is to measure directly: measure from the top of the thread to the underside of the bolt head (do not include the head itself). Front bolts are usually the same length, most often around 15 mm. Rear bolts are almost always different, so be sure to measure both individually. A difference of about 1.5 mm longer or shorter is acceptable and will not affect performance. Remember to use threadlocker.

Why normal bolts are flawed
When it comes to braking performance, alignment is everything. Yet most caliper bolts—even premium titanium upgrades—suffer from the same flaw: excessive friction between the bolt head and washer. As torque is applied, the caliper shifts out of position, turning a simple adjustment into a frustrating, time-consuming task.

Why it happens
Standard hardware is usually left uncoated or treated with black oxide, both of which create high surface friction. Even titanium-on-titanium setups aren’t immune. Without the right surface treatment, the interface drags, pulling the caliper off-center just when accuracy matters most.

Our Solution: Ultra-Low Friction Interface
By applying distinct PVD (Physical Vapor Deposition) coatings to the bolt and washer, absoluteBLACK creates an interface with exceptionally low friction—allowing torque to be applied smoothly without disturbing caliper position. This innovation makes setup faster, alignment more precise, and braking performance more reliable.
