Radius Mini V-Brake Caliper Set - Front & Rear - 76mm arms - w/Cables &

Radius Mini V-Brake Caliper Set

• Front and Rear - 2 Sets of Calipers
• Not only are these shorter than standard V-brake arms, they appear to be extra-short, even for mini-V's!
• ATTENTION: MEASURE CANTI POST-TO-RIM VERTICAL DISTANCE BEFORE YOU BUY THESE!!!  Information dump about mini-V spacing and potential fit issues: The length of these arms is significantly shorter than "standard" V-brakes, which are often around 107mm, but this number can vary slightly depending on the model. Mini-V's are often between 80mm-90mm measured from the center of pivot to center of cable clamp, but these Radius arms are even a bit shorter, at just 76mm C-C for whatever reason. I took some very careful measurements, and it looks like if your canti posts are high up and quite close to the center of the rim brake surface (as close as 20mm under rim center), you can likely fit up to a cushy 42mm (possibly even a 45mm, if everything lines up just right but let's keep a margin of error) width tire using these brake arms without the linear-pull cable and hanger rubbing the tire. However, if the center of your mounting posts are as low as 37mm underneath rim center, you will have to position the brake pads all the way up in the mounting slots to have the pads contact the rim, and will then likely be limited to a skinny 28mm maybe even a 25mm width tire. If the center of your mounting posts are more than a millimeter closer than 20mm or further away than 37mm from the center of the rim, vertical distance, do not buy these as they will not work well for your application. 
• These are short-pull ratio, unlike standard V-brakes, which are long-pull, which means they are compatible with brake levers designed for short-pull brakes such as side-pull caliper, center-pulls, U-brake and cantilevers (if the spacing works, as again they are quite short and will not clear over a large tire)
• Pads, Cables, Housing, and Noodles included
• I think the part number is RA30
• New in original box
• Some wear to box
• NO LEVERS INCLUDED (the boxes indicated they're includes, but they are NOT)
