Fits all bikes with 108mm Radial Mounts. Please check with us before ordering.

The body of this caliper, which is the very best currently available, is entirely billet and is made up of two pieces which are mechanically connected. Particular attention was dedicated to finding high braking power and stiffness values, obtained tanks to painstaking design, the use of carefully selected raw materials and ultra modern metal machining technology discoveries. In particular sophisticated topological optimisation software was used capable of pointing out to the designer the areas where excess material could be eliminated and vice versa.
The hydraulics were the focus of a careful fine-tuning thanks to the use of four 32 mm diameter pistons which allowed a further increase in braking power and modularity specifications.
This model implements a surface finish borrowed from MotoGP. In fact, the nickel plating, in addition to giving it an aggressive and attractive look, allowed the already strict machining tolerances to be refined, all to the advantage of performance and operating precision.
The brake pads slide in specific guides, machined onto the body of the caliper itself, which have made it possible to eliminate brake pad pins.
The Brembo logo is embossed and hand painted in classic Brembo Red. The product, provided in a kit, includes sintered brake pads which represent the absolute best quality available on the market today. The kit also contains an instruction manual, a set of Brembo stickers and extremely useful heat adhesives used in racing to control caliper operating temperature, which are indicative of the product racing nature.

This product can be sold only in conjunction with: Spacer + screws kit. Please add to your order if required and add a note with your order which bike these are for including fork and disc combinations.

Solid Floating Shelves 🛠️🏠
Color: Black, Number Of Shelves: 4, Size: 15.7in
I have installed four sets of the black floating shelves in my office. They are made of high quality materials, featuring a sophisticated black woodgrain finish with a natural texture. Supposedly, each unit can handle up to 22 pounds, though I would not recommend testing that limit with your vintage bowling ball collection if you value your flooring. They are awesome. The value is good for a set of two. Each shelf measures 22x7x1 (56x17x3 cm) inches, providing a decent amount of storage for books or decor. The installation was straightforward since the hardware for multiple wall types was included. They work well in the kitchen for spices or in the bedroom for personal belongings. One tip for a secure fit: use a level during installation and make sure the bracket is flush against the wall before sliding the shelf on, or your photos might look like they are sliding off a mountain 📐 These shelves offer a clean, modern look and stay stable once mounted correctly. They are a practical choice for adding functional display space to any room 🖼️

Good looking shelves and easy install - skip the included drywall anchors
Color: Black, Number Of Shelves: 2, Size: 22in
I installed these shelves in a bedroom to get things off my dresser and some decor. Once mounted they look really nice. The black finish looks clean and modern and they blend in well with the room. Installation was pretty straightforward. The metal bracket mounts to the wall first and then the shelf slides over the bracket. As long as you take your time lining things up it’s a simple project. One thing I strongly recommend is not using the white plastic self-drilling drywall anchors that come with the kit. I’ve used that style before on other projects and they tend to strip out easily and leave larger holes in drywall. I used better anchors instead and the shelves mounted much more securely. The rest of the hardware worked fine and once installed the shelves feel solid and hold items well. Pros - Clean modern look - Easy installation - Feels solid once mounted - Good size for books or decor Cons - The small level included isn’t very accurate — use your own level - One of the metal brackets was slightly bent out of the box but straightened out easily Helpful tip: Use your own level and better drywall anchors if you have them. It makes installation easier and the shelves will mount much more securely. Final thoughts: For the price these are nice looking floating shelves that install easily and work well for light storage and decor.
