Wheels arrived, along with most of the other parts. I mounted a pair of Panasonic Minits, the 20/1.25 tires are 170 grams. I used Panaracer tubes, which were a little troublesome, as they seemed too long. I visited a local shop today, and they had a new set of XTR 10 speed shifters for only 10000 yen, and, amazingly, a new XTR 10s cog set for only 8000 yen, so I sent the XT cog set back. I mounted the wheels, shifters, and derailleur. The shifters do not work well with Promax brake levers, so those will have to go. The chainset will arrive tomorrow, but I can't install it until I get some bottom bracket tools.

The brakes don't line up with the 20" wheels, the two options are to use longer brakes, which have reduced leverage, or adapters which move the brakes outward. I will go with the adapters, and use a XTR brake set.

So far all mods are easy, everything is bolt-on. The LBS has an interesting aftermarket chain tensioner which replaces the standard wire steel tensioner, they also have an accessory to keep the chain from falling off the chain ring. I may try these just to see how well they work.
