[RBW] Re: Question 27" wheel conversion to 700c wheels and maybe to 650b
Hi, Hugh. When my 1972 Sports Tourer started breaking spokes, Rich Lesnik built new 700C wheels with Synergy rims on my original hubs, which look like the Phil 'Rivy' hubs. Thus it needed no frame spacing change in the rear; and the O/C rear wheel improved the strength of the 120mm-spaced rear wheel. It's been all good since! I kept the original center-pull brakes by extending the shoe slots with an endmill to gain the 4mm or so of adjustment required. That's not a recommendation!! A brake with more reach would have been the safe approach. I looked over my '90 Bstone MB-1 with XT cantilevers, and if yours are similar, the brake shoe post will have to angle downward to contact a smaller wheel's rim, because there is no adjustment for rim diameter. I don't like the prospects - some of your braking force will be lost to a bending moment applied to the shoe's post, and the angled shoe will have more chance for tire contact. Those are old brakes, and mine are old eyes. Maybe the adjustment you need exists in a modern brake, or maybe I just didn't see it. So take a good look at yours!

I've had similar very annoying experiences, and have always found a cause located inside the tire: a slipping rim strip; a loose wire bead; a penetrant stuck inside the casing and impossible to find just by looking at the tread. To paraphrase Dr Johnson, such an excess of flats is not in nature. (Johnson said, "Such an excess of stupidity, Sir, is not in nature.")

Re: [RBW] Re: Question 27" wheel conversion to 700c wheels and maybe to 650b
i will echo what steve says, measure! i made the same assumption a few years ago (still have the bike), and did the conversion because the existing wheels were chromed steel (in poor condition), the back was no issue even with short reach side-pulls. but the front fork had tons of tire clearance already, so switching out to even long reach side-pulls didn't work, i used a make-shift drop-bolt for a few years until i found a crazy long reach sidepull (~75mm ish) made by shimano which i'm using now. This was not an uncommon occurence as i think campy or dia-compe made machined drop bolts a long time ago.

Freedom from hassles is a matter of having sufficient reach. I recall seeing some 27" sidepull frames back in the day that had enormous clearance, and barely made it with long reach sidepulls.

Re: [RBW] Re: Question 27" wheel conversion to 700c wheels and maybe to 650b
Is it safe to say the following in general: On an older 27" road frame, switching to 700C on a frame with Sidepull brakes is hassle-free, but on a frame with cantilever brakes, there will often be problems with pad alignment.

[RBW] Re: Question 27" wheel conversion to 700c wheels and maybe to 650b
I did a conversion on a Trek 620 a while back, the brakes couldn't make the adjustment. The REAL problem is that the brake posts are much more narrow on the 27" bikes and modern brakes are designed for the wider brakes designed after the mountain bike transition. Look more a pair of old smooth post Deore XT cantilevers, they work great. I highly doubt they'll drop low enough for a 650b conversion though. Honestly, I'd just stick with 700c so you don't have to do a conversion, I don't see a big point in doing 650b conversions unless there is no clearance in the original frame; a bike made with 27" wheels and cantilevers is likely a touring bike and should easily swallow some 700 x 35's.

Actually Schwable, Panaracer and Continetial to name a few still make good quality 27inch tires.

I agree there are many good 27" tires still made, including Pasela TG folding bead - Nashbar just got a new inventory of these. Schwalbe Marathons and Contis at the other end of the weight and toughness spectrum. Also agree that you can't always make the swap. My rear centerpull, Weinmann 750 is just not quite long enough to reach a 700c rim.

[RBW] Re: Question 27" wheel conversion to 700c wheels and maybe to 650b
My experience with 27 to 700c was yes, but not as easily as I had hoped. When I tried to mount a pair of Paul's neo-retros I found that the slot for the shoe wasn't quite long enough, but the original dis-compes, with traditional pivoting shoes could be positioned OK, just at a bit of an angle. I don't see how you could get to 650b without removing the studs. Then you could probably find a center pull which might work. If you can live with a paint touch up, this is not too expensive a solution.

[RBW] Re: Question 27" wheel conversion to 700c wheels and maybe to 650b
Why are you wanting to convert from 27" (630) to 700c (622)? It's not a noticeable difference. The tire/rim availability of 700c is the only real reason (and there would be a fraction more clearance with 700c), but there are various options for the old 27" (630) standard. Jensonusa.com carry a fair selection of tires and even have a budget price wheelset for screw on freewheel that works for 126mm spacing. I converted from 27" to 700c on a bike because someone sold me a cheap (but good) 700 wheelset, complete with tires. I must have re-spaced the rear triangle, but the brakes needed nothing more than realigning the pads. I could then run either 27" or 700c within a range of 126mm to 130mm with no problem as long as the brake pads were realigned each time.

[RBW] Re: Question 27" wheel conversion to 700c wheels and maybe to 650b
Hi Shoji, That's what I thought. Moving the Canti Bosses would be out as the expense would negate the attempt at saving money. So probably 700c.

[RBW] Re: Question 27" wheel conversion to 700c wheels and maybe to 650b
If you have the 4 mm adjustment in your brake shoes, no problem converting 27" to 700C. Rear axle spacing (width between dropouts) is very important, though. Most 27" bikes have 120mm rear axle, initial 700C were on 126mm spacing, and most bikes/ hubs today are on 130mm or 135mm axle spacing. Sheldon has a good article. http://sheldonbrown.com/frame-spacing.html I'll leave the cantis to someone else.

Hi Hugh, 27" to 700C should be pretty smooth. The radius difference of 4mm means you need that much additional brake reach. Hopefully you can move your brake pads in your cantilevers down (toward the dropout) by 4mm? Here's a VO blog post: http://velo-orange.blogspot.com/2011/10/27-wheels-and-measuring-brake-reach.html Conversion to 650B is more involved. It may be doable, but you'll need to measure more things and relocate your canti bosses. Good luck!
