Ebay's not coming up with anything. Try direct sellers. They have some 29'ers in 23 in your price range.>>1317498
Looks like a made in japan miyata 210, about 1981 or 1982 or so. It's the only one made in your size in their entire lineup. It's not a racing bike, but this is close to the height of Japan's steel bike power level.
The price is so so, but it looks to be in outstanding condition. Even if he won't move on price, ask for things like a saddle that fits better, maybe a stem swap.
If you want to go old steel 10 speed, this is the obvious and probably only choice. Whether you buy it or not, you should 100 percent talk to the guy. He obviously has a bunch of other bikes in his garage, and if he's stoopidtall, he's got a very good chance of having something else suitable for sale, even if this one isn't. >>1317506>Do you think it would hold my weight?
I'm not going to guarantee a thing at your weight, but those are some serious wheels, and this was Miyata's largest frame. The only thing stronger would be double wall MTB rims and loaded touring rims.
Learn proper riding technique, and learn how to use a spoke wrench.>>1317554
Given the restoration work and the leather sprung saddle in one pic, I'd suspect this was his primary bike and that he's upgraded.
