Velocity is the name of his Bike & Bean shop (coffeehouse/bike shop). No connection to the rim manufacturer. I'll offer that into the discussion.

fwiw - I have some very low profile pads that are on the Alivio calipers that are going back on the re-imagined Giant Iguana project that I'm working on. Those calipers also have adjustment slots that are at least 15 mm on them. I'm 99% certain that combination would work just fine for your application. I'll poke through some more of my stash to see what other forgotten goodies I have left from a care package that a couple C&Ver's sent me a few years back to help properly outfit some of the Scout troop members' bikes with functional brakes. Glad to pay it forward if I have something that suits.

I checked the parts bin, and only have one pair (one wheel's worth) of old XT calipers. Not enough for a whole bike, but you're welcome to them if you want them.

Pretty sure that if your calipers won't contact properly, step one would be to get low profile cantilever brake pads (if you don't already), and see if that fixes things. Step 2 would be to get either some used Alivio, or XT calipers, and use the low profile pads.

I ran a 610 with 700c wheels and the stock brakes without the slightest problem. This was essentially the same frameset, and I believe the exact same Dia Compe brakes.

I thought he said I didn't have to work?

Thanks for the parts offers. I'll keep them in mind. Anecdotes of other Miyata 700C conversions are encouraging. Except for the central drivetrain, the more I can keep stock, the better. I'm guessing I'll have a basic "rolling chassis" around the end of the week.

EDIT: I found a site with the Dyad's precise measurements. The brake wall height is apparently 9.8mm.

Thought I'd follow up - the original Dia Compe 960 brakes work fine as-is. They only thing they needed was a new set of Kool Stop Salmons; the old ones were several decades old. The bike is nearing completion.

BTW, the reflective stripe on Schwalbe Marathon Supremes *really* catch light!

wrap the bars, flip the seatpost, toss a saddle on, and you are done!

It still needs some work. It's assembled, but still needs a good set-up. That's just a post they threw on the bike as a hand-hold. I found the original post and seat (but that butt killer will not stay). I figure pedals are kinda important too. But it's close. The long and sordid story of this bike is over in the Bike Mechanics sub-forum.

Or you could flip the bars, wrap the seatpost, toss the saddle out...

I really like the original 27" wheels on my 1000. Those Araya rims are pretty much indestructible.

Phreon

Yeah, but my Dad cannibalized those rims (well, the rear) for his custom recumbent. And the crankset... They still are great rims, but I didn't get them with the frame.

I suppose if one has a 27" ready to go, stay with it but if planning some serious touring, go with a 700c conversion. Well worth sorting the brakes out and change if needed. For a 700c, go with a wider rim and also pre-drill for a Schrader valve. Reason is the greater variety of tire choices but also plentiful on most store shelves (including tubes with Schrader valve). The other is carrying a pair of foldable spare tires and double the fun. For those times you want to leave camp for the day and explore back trails and no load, swap out to a lightweight cross tire.
As for the rims, 36 hole is the safety margin and when you might really load up, or occassional run for firewood, etc..

Big fan of vintage Ukai box section rims. Happy medium light but a thick side wall to offset potential dings from monster pothole hits. The seam and machining is a piece of quality.

I think there must be some sort of support group for people who have a parent who is a cannibal.

If it's at the shop already why can't they just toss on some CR720's to see if they'll work? Given they have some in stock. The Tektro Onyx also has a lot of adjustability and very reasonable in price.

Phreon

I don't think you and a few others actually read the posts. I've already stated the bike is almost complete and the original Dia Compe 960s work as is. Those are 700C wheels in the picture.

Phreon

Hehe, funny. I can't blame him in this case. My Dad rode the hell out of the Miyata and Ross Mt. Rainier. Until one evening while he was out on a ride, his biking buddy called us from a payphone. His back tweaked/spasmed so badly that he couldn't get off the bike. She left him leaning against a wall and rode away to find a phone to call for
an ambulance. The last journey the 1000 took with my Dad was inside an ambulance. He transferred the rear wheel and drivetrain from the '1000 to his "Lemle Lightning" recumbent (Lemle of Swanton, OH) he acquired because of his back issues. The Miyata's wheel and original parts still live on on the Lightning to this day.

I'll have to check out that thread!

It's way cool that this was your dad's bike. Your dad's bike that just so happens to be one of the most well regarded bikes...

If you enjoyed this thread (I certainly did) it's worth it checking out the one in the Bike Mechanics sub-forum as well.
