R20 brake + wheel upgrade
I'm looking to upgrade the wheels on my R20. At the same time this will likely mean upgrading the brakes. I currently have Altenburger caliper brakes (I'm assuming this is stock). I'm trying to decide between 406 and 451 wheels. Ive heard that with 451 wheels you can use a standard brake caliper vs having to use a long reach style. Is this correct? I plan on keeping the fenders so I will need a caliper to fit around them.
If I need long reach style calipers what size or model have people used. I heard tektro long reach calipers will fit but I could not find the exact model or length.
Is there a large benefit to upgrading the old brakes? Mine currently dont really work but I'm pretty sure I could get them going with a bit of effort.
Is the only benefit of using 406 wheels the greater availability of tires?
Thanks for the help.
