Re: [RBW] Replace 27 wheels with 700c or 650b? Brakes = Silvers
I switched a Raleigh Marathon Mixte from 27 to 650B with Silvers and had no problems. Plenty of reach. My LBS did a great job of coldsetting the rear triangle to 130 for me.

Early indications are that 700c is fine, but there may not be enough reach to make it out to 650b. As for the nutted brakes: I picked up my recessed Silvers at a Riv garage sale a couple of years ago (missing the attachment fittings for the QRs, which I cannibalized off salvaged brakes from bike kitchens). At the last Riv garage sale in July, I found several pairs of huge Tektro sidepulls that Grant IDed as parts for some abandoned project; Tektro lists them for beach cruisers. Fortunately, they had nutted bolts, and Riv was selling them for $5/pair. The bolts were not easy to get out of the brakes, but they fit the Silvers just fine.

So you really need to determine the wheel size first before selecting the brakes. Also, unless you can score brakes that uses nut instead of recessed allen, you will have to drill the frameset to use most recess-allen-equipped brake calipers. I tend to use center-pull brakes for these conversions for easy and inexpensive sourcing, as well as better braking power. -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

[RBW] Replace 27 wheels with 700c or 650b? Brakes = Silvers
So after selling my Sam (sniff sniff), I scored a 1985 Trek 420 with 27 wheels. It's a beautiful lugged frame that looks like it was barely ridden and I can't wait to get my collection of Rivy parts on it: SunRace thumbshifter (singular, no front der), Dirt Drop stem, fancy drilled Tektro levers, etc. Here's the hard part. I'm a hefty lad and need/want a fatter tire than the fattest 27ers made. The Trek has a rear hub spacing of 126mm and I don't really want to cold set it to 130mm. At 126mm, options seem limited to freewheel hubs. I'm ok with that, but all the prebuilt 700c 126mm wheelsets have skinny rims for skinny tires. So it seems I need a custom rear wheel - 126mm hub with a rim that will accommodate 38-50mm tires. If I'm going to have a rear wheel built on a 126mm hub, would it be preferable to go 650b or 700c? Can I really get that much more air volume with 650b tires? My rough measurements suggest that with 700c the rear will fit 38mm tires. With 700c, I might? even fit a 50mm Big Ben on the front a and a little Ben on the rear. While 650b theoretically will allow a bigger tire, I'm not sure a 650b Big Ben will fit the rear, which might put me Assuming that the Silvers will work for either size (reach the 650b rims), which size might be best? I think either would be fine/ok, am I forgetting anything? Should I REALLY not rule out cold setting to 130mm and going with a freehub wheel?

Remember that you'll be dropping the bottom bracket quite a bit if you go to 650b. 700 sounds like a good place to go. Granted, if you put FATTYS with 650b then you don't drop all that much but you get my point.

Re: [RBW] Replace 27 wheels with 700c or 650b? Brakes = Silvers
BB drop is a concern, but if you look at the geometry of these old Trek road bikes their original BB drop is in the low 70s, which makes them good 650b conversion candidates--and therefore you will see many examples of old Trek 650b conversions on the internet. Given that you will be using at least 38mm wide tires compared to the 23mm 27 tires, the final BB height would be pretty close.

Re: [RBW] Replace 27 wheels with 700c or 650b? Brakes = Silvers
actually, since the old 27 tires were most likely measured no more than 25mm wide (even if they were marked 1 1/8 or 1 1/4), going to 38mm 700c tires actually raise the BB height noticeably. 650b/38mm tires are likely to be closer in wheel/tire diameter to 27/25mm than 700c/38mm.

Re: [RBW] Replace 27 wheels with 700c or 650b? Brakes = Silvers
I'm skeptical you could fit a true 700x38 in there. On my '83 620, I have good clearance with an actual 32mm tire (Performance Metro 35), but not enough room for a fender. On a previous 27 -- 700c conversion (an old Fuji S10S), I could fit a true 35mm Pasela in there, but it was nearly scraping the brake caliper undersides. On Trek conversions I've read about, most folks struggle to fit a 42mm Hetre in there. 650B x 38mm is an easier fit, which I think typically also allows for fenders.

Re: [RBW] Replace 27 wheels with 700c or 650b? Brakes = Silvers
I agonized over these numbers for months before converting my older Rivendell custom to 650b. Why speculate? It's 23 mm lower to go from 630 (27) to 584 (650B) whereas it's 19mm to go from 622 (700c) to 584 (650b). So, there's not much difference between a 27 to 650b conversion and a 700c to 650b conversion. Less than half a centimeter. Some of the distance will be made up by the larger tires, so there's that as well. Someone else said BB drop was in the lower 70s on your Trek so you're in better shape than I was with 80mm drop. Many old Treks have been converted to 650b and AFAIK most owners have been happy with them. There's pictures all over the Internet. If you are absolutely sure that a 700c x 38mm tire will fit, then 700c could be ok, but if there's any question, go 650b. I did and I have been very happy running 650b x 38mm Compass LoupLoup Pass. I'm also a really big guy and i recommend staying away from Velocity Synergy rims. Had to send one back with cracks along the spoke holes. I've had good luck with their Atlas rim so far though that they rebuilt the wheel with.
