My 10 year old son has a Redline Raid he got about 2 years ago. Probably one more year on it before we have to upgrade him to a larger bike. It has a coaster brake and a rear V brake. I'm thinking about adding a front caliper brake since there is a hole in the fork crown where a caliper brake could mount--unless it's simply a fender mount hole.

Tires are very knobby (57x406 front, 47x406 rear) and starting to show a bit of wear, so I was thinking about swapping on a set of road tires when I add the caliper brake. He's not an offroad bike riding kid, even though he sometimes imagines he is.

I wanted the front hand brake to get his brain thinking about hand brakes, since his next bike will likely be a multispeed with hand brakes. Also, his 22 month old brother will eventually inherit the bike, so I don't think it's a bad investment.

Any info or links about performing such a surgery would be greatly appreciated.
