So I picked up a very abused miyata six ten in my size the other day, intending to make it my new ultimate tourer/commuter, and was bummed out because when I grabbed a spare 700c front wheel and put it in the fork the canti pads didn't line up and my searches turned up that chances were dicey at best for a successful 27"->700c conversion... :(

So I go down to my makeshift bike shop, determined to try anyways, and mount a spare 700c wheel in the rear this time instead of the fork, and low and behold the random cantilevers I have align perfectly. I check the front with the same cantilever, and sure enough, there is ~4mm difference...

Why is this? Did Miyata make one version of the frame and two versions of the fork and shipped the bike with 700c's in europe/asia and 27" in the US? Inquiring minds want to know...

I'm very pleased in any event as the fork is beat up, bent, and heavy. Now I've got an excuse to upgrade it... :D

AFAIK, all early Miyatas were 27" everywhere. I guess the later models may have been 27" in the US and 700C elsewhere, but I really have no idea.

My husband upgraded his 1984 Six Ten to 700C wheels, he kept the original DiaCompe cantis and had to adjust the reach and angle to get them to work with the new wheels. It wasn't a particularly difficult process. So you might want to check if you have enough adjustment in the brakes to do this.

I also upgraded my 1982 610 to 700c wheels and had no issues with making the adjustments in the Dia Compe cantis to get the pads onto the rim surface correctly. It was very easy.

Does your bike have the original fork?

Yes, I assume so as it has miyata stamped on the crown... its odd that the canti mounts are so different from the front to the back...
