Thanks for the tip Rory. Can you tell me how the shop you went to counterbored the holes to fit the spoke washers in the way that they did it? I stared at the damned things for a good half hour thinking they should just slip in. I decided after that since they were so easily bendable that it didn't matter much and pushed them home to the bottom of the spoke hole with a punch of the appropriate size.
The instructions I received called for doubling the washers so they wouldn't pull through. I have a forstner bit that I could use to counterbore, but I'm kind of shy about cutting into my new rims. Of course if they explode from being laced wrong that won't be any better. I have plenty of washers so I can redo it if need be.
As far as the WTB tires go. They're pretty nice. I have them on my '82 Trek 420 and although I had to pinch the rear chainstays to get the 700-38s to fit, they're cushy, grippy, and pretty nice for the crappy roads around where I live. Recently I've been riding my 29er on the country roads and I'm considering putting a set of these tires on it to make it go a little faster (averaging 10 mph over rolling hills with 2.35" knobbies) I like the chevron pattern of the tires. Looks a little more believable to me, but that's just one opinion. Amsterdams have a gross looking tread when you get up close, but they do look good from 20 feet! Will whoever makes them come out with a button tread or vaccuum cup tire already!!!? Hell a 700-38c smoothie in white would be better than nothing and super easy to make.
