Want to change the calipers on my Sirrus. It has v brakes,700mm wheels. Searched the web and it should need Long arm cantilevers. From what I can see the Shimano LX calipers in standard form for MTB will not be long enough. Has anyone in LBS out there come across this.
There is no major problem with the existing calipers just looking at upgrading. Don't know if some of the AVID v brake systems would work

Thanks
