Shimano RS505 C-mount bolt

Answer of Joaquim

On this website, the size to buy corresponds to the size of the chainstay of the frame, NOT the length of the bolt. In my case, I bought this bolt in the 35mm size (for the Cervelo PX-Series frame) and the bolt measures 48mm. For a 25mm frame, the bolt will measure 38mm. Check the instructions in your bike´s manual and it will specify what length you need to buy. It is logical that the bolt is always longer than the chainstay of the frame, otherwise it is impossible to screw it in. Correct, 25mm is Y8N208020!

Answer of Dennis

Yes, that is correct. The 25mm refers to the thickness of the chainstay of the bike.

Hello, To find out which caliper screw you need, you must go to the Shimano technical site, filter by MTB/road/... Then filter by transmission group and look for the brake "reseller manual" that corresponds to the mountain bike universe/group concerned. Everything is detailed how to mount the hoses, discs, calipers etc... The screws depend on the caliper and the thickness of the frame on the caliper area which must be measured by removing the caliper and measuring with the foot at slide in general thickness of the base at this location + nipple which receives the screw, for the road it is generally standardized multiples of 5 it makes 20, 25, 30, 35 thick I think that for mountain biking it´s is the same. You will have a table with the screw lengths and screw references. This screw is allen type and I used it for road calipers, I don´t think it is suitable for your needs. To find the documents in Google you type "shimano technical document" or "si.shimano" then you will have to browse the menus to find the right document and you will have the information. Or try in English in google "bolt for xt br-3120 caliper" you may get directly to the right document like this or by selecting "images" in google on the table you need.

Bonjour, Pour savoir de quelle vis d'étrier vous avez besoin il faut aller sur le site technique shimano, filtrer par univers vtt/route/... Filtrer ensuite par groupe de transmission et chercher le "manuel revendeur" freins qui correspond à l'univers vtt/groupe concerné. Tout est détaillé comment monter les durites, les disques, les étriers ect... Les vis dépendent de l'étrier et de l'épaisseur du cadre sur la zone étrier qu'il faut mesurer en retirant l'étrier et mesure au pied à coulisse en général épaisseur de la base à cet endroit + téton qui reçoit la vis, pour la route c'est standardisé en général des multiples de 5 ça fait 20, 25, 30, 35 d'épais je pense que pour le VTT c'est pareil. Vous aurez un tableau avec les longueurs de vis et les références des vis. Cette vis est de type allen et je l'ai utilisée pour des étriers route je ne pense pas qu'elle soit adaptée à votre besoin. Pour trouver les documents dans google vous tapez "document technique shimano" ou "si.shimano" ensuite il faudra se balader dans les menus pour trouver le bon document et vous aurez l'information. Ou alors essayez en anglais dans google "bolt for xt br-3120 caliper" vous arriverez peut-être directement au bon document ainsi ou en sélectionnant "images" dans google sur le tableau dont vous avez besoin.

Hi, the bolt is used to secure the brake body to the frame. For the measurements you must refer to the thickness of the rear stay of the bike and add the thickness of the point of the brake body where the bolt will be inserted and consider that the lower part of this will have to protrude before inserting the safety pin.

Salve, il bullone serve per fissare il corpo freno al telaio. Per le misure bisogna fare riferimento allo spessore del carro posteriore della bici e sommare lo spessore del punto del corpo freno dove dovrà essere inserita il bullone e considerare che la parte inferiore di questo, dovrà sporgere per poi inserire la spinetta di sicurezza.
