Exchange from Ultegra, Brake Shoes such as Mini Bello R451. There is no doubt the power after exchanging with a brake shoe in 700C as well as a cheap model of mini bello. If you think it is an exchange every year? 3000 yen is safe and secure.
When traveling on a wet wet road, braking was suppleted more than shimano genuine. It is the use of genuine shoe main body with rubber exchange. Unfortunately, because the mounting surface to the caliper is curved, it is necessary to pinch the concave washer, but the caliper will spread by that much (because the clearance between the shoe and the rim is constant). As a result, the adjuster of the wheel detachment does not work (the cam is caught). It is a combination of 6500 Alte Gras caliper and Easton EA 90 RT (rim width about 22.5 mm). If the rim width is wide, I think that it may be like the above condition and that it is better to display the recommended rim width.
