i used modern tektros on these two 700c conversions. because the long reach r539 reaches the front but not the rear, i use two different models, with the extra long reach r559 caliper in back.
'73 falcon
'76 mb grand record
using the shorter caliper on the front looks a hell of a lot better. too bad it won't reach the rear without tire rub ... but at least i was able to order these brakes separately as opposed to a set. on both bikes i paired these brakes with the comfy and gum hooded scr-5 aero levers.

This has a Schwinn Approved DiaCompe 610, which works great.

As usual, I'm stunned by the photos of y'all's bikes, and especially that green Supercourse (drool).
Since I put in a 5-hour, 82-mile ride today on my current "Austrian Varsity" bike with 700c's on it, I'll post it again. More realistically, I should have said "Austrian Continental", but anyway it's really a Steyr/Puch.
I finally got the original Austrian-sized headset sorted out after finally doing the cotter bb a couple of weeks ago, but haven't changed anything visibly since this one was taken:
The stock headset has light(!) thin steel cups and had 14-ball(!) retainers, which had dented the crown race and lower cup.
Rotating both the lower cup and crown race 90 degrees in opposite directions (and adding fully 26 balls to each race) made the adjustment process a heck of a lot easier and has exorcized the twitchy, wandering feel I had previously experienced when trying to hold a fine line near the rough edge of the road at speed.
The premium 700c wheels and tires cut a full two pounds compared to the original steel rims and Michelin Hi-Speed gumwalls, with much smoother and safer braking as well. The front caliper's pads are now nearly at the very bottom of the slots, simply because the front Weinmann caliper has a shorter-reach than the rear.

I hope this thread/topic hasn't become a dead horse. Does anyone know if Shimano CX70 cantis will work on a Schwinn Voyageur for the switch to 700c? Most people I see online are using Dia Compe, Deore XT, Deore LX (evrything other than CX70)I'm considering purchasing a 1990 Voyageur and accompanying Phil Wood BB from a dude on CL, but I have a set of White hubs laced to A719's. I also have Shimano CX70 canti's. The CL deal is smoking. But I'm not willing to reinvest in parts for this Voyageur.

I changed this a few years ago to 700c (Record hubs, DT butted spokes and Mavic Pros). Long drop brakes fitted.

Have done several builds with this conversion and had few or no problems. Early/mid '80s Univega and Centurion mixtes, '82 Trek 515, '84 Trek 620, '86 Univega Gran Turismo. Maybe a couple more. Ended up with wider tires and fenders on most. The stock brakes were used with adjustment on some and the builds from frames only (620, Gran Turismo) worked well with DC 986. Seem to remember on one build having to deepen the slot on a side pull caliper by a couple of mm to match the pad to the rim.
620 GT Incomplete 515 on the end.

My brother-in-law bought this bike new. it had been hanging in his garage for the past 15 or 20 years, so I asked him for it a few years ago, and he gave it to me so it was "free". At least that's what I told my wife.

27x1.25 tires are 32's, you should be able to go bigger on a 700c tire in a 27" frame. Personally, I like 27" tires in concept better due to larger size. I got a set of Club Roost Cross Terra 27x1 3/8" tires for my Schwinn Passage and they fit great, wonderful gravel tires.

My most-converted bike ever: 1972 Lambert frame with
- cast aluminum death fork converted to Tange steel fork
- converted from 10-speed to 18-speed, then to 8-speed IGH
- drop bars converted to upside down M bars then back again
- standard brake levers converted to aero
- 27" rims converted to 700c (29er)
Those wheels came with disc-brake hubs and non-machined, non-flat rim sides, but the ancient Racer calipers work just fine on them, even with the old set of DiaCompe brake pads they came with. The Velo Orange 45mm stainless fenders fit this bike a lot more easily than the Nishiki Landau I had them on earlier, running the same tires. I may trim down those fender stays a bit, but not until I've ridden the bike in this configuration for a while. Since I first started messing with it about 5 years ago, it's never gone more than 6 months without some significant change or upgrade. The only parts on the bike that are correct to the original frame are the Lambert of England crank arms, I think. And I bought them on eBay after I'd owned the bike for over 30 years

Thanks! One of these days I'm going to tear it all down again and finish painting it.

I don't have one at the moment but I did this one about 15 years ago.
I do have a couple waiting in the wings but I don't know when I'll get to them.

Both my Mercian and my Jack Taylor were most likely built for 27" wheels. Both are sporting 700c wheels now. The Mercian is using a Weinmann 610/750 centerpull set, while the JT eeks by with a set of Racers with the pads all the way at the bottom:

When he initially built it, it had Velo Orange Grand Cru brakes:

I had an 86 Voyageur with DiaCompe 981s that did adjust to 700c without going too goofy angled using Kool Stop Eagle pads.

My late 60s Dawes is a 27" to 700 conversion. Probably my favorite bike; not much on snob appeal, but rides like a dream. Nothing like a campy nuovo record wheelset to upgrade your ride! Challenge Almanzo tires (30mm) ride nice too!
My De Rosa rides better and is a touch faster but is a fair weather bike with 23mm sew ups.
I definitely a have a sense of satisfaction from rescuing a bike that was languishing away and riding the wheels off it!
