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
Two Marathons = a kilogram. 3-1/2 folding Paselas TG = a kilogram

I got flats every 1/3rd of a mile with gatorskins. Sometimes it's fun to
breakdown and repair, the satisfaction of rolling again after a forced stop is
great! But if you'd rather just ride your bike straight through the day go
with the schwalbes.

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.
Yeah, I was exaggerating.
My point was gatorskins=bad, schwalbes=good

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
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

I agree there are many good 27 tires still made, including Pasela TG

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,

Actually Schwable, Panaracer and Continetial to name a few still make good
quality 27inch tires. I agree that you do have more options with 700c but
that doesn't mean there are no good options for 27inch.
Hugh check my posting here is you want to see what your options are today
for 27 inch
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

Freedom from hassles is a matter of having sufficient
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

Fair enough Steve, how would you rate the Conti Gator Skins or Schwalbe
Marathons
which also have 27x1 1/4 options?

I don't know Contis at all. The Marathons are a heavy duty touring
tire. Where do they sit in Schwalbe's hierarchy?
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:
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.
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. Thanks,
Hugh
