Wider wheels on Cannondale touring bike

[Viktor]

I bought a Cannondale touring bike in 1990 with a 27" frame, something that is not so easy to find
anymore. Just my luck, I permanently trashed my knee soon after I bought the bike (not on the bike,
though). So, I am a definite Sunday rider now. I've never been lightweight, as I'm over 200 lbs
(not fat at all), and those skinny tires & wheels are just too much for me now (or I should say,
just too little for me now). So I want to get a set of thicker tires & wheels. I must admit, I also
would like to take it on dirt roads (NOT mountain biking trails, just dirt roads). So, admitting
that I am not a bike techie, how difficult will it be to install wider tires & wheels on the bike?
It came with Deore LX components. Looking at the brakes, it seems that I will have to buy entire
brake shoe/caliper units to allow for the wider wheels. Can I just go into the bike shop and have
them install wider wheels, wider tires, and two shoe/caliper units? Feel free to give general or
specific advice.

If it was really built as a touring bike, you should be able to fit tyres up to 700x35 at least
without changing anything other than the tyre and tube. We've toured many tens of thousands of
kilometres on a tandem equipped with that size of tyre, and the two of us together outweigh you by
about 60 or 70 pounds, plus we've carried up to 100lbs of luggage as well when cycle camping.

The only time we've ever had problems with the tyres has been on very rough dirt roads with that
100lbs of luggage on board. The sort of road where you find signs apologising for its state: "Worst
main road in NSW" (council sign on the road between Murwillumbah and Nimbin); "Due to inadequate
government funding we are unable to maintain this road" (council sign on the road from Crookwell
into the Wombwyan Caves)...

I think you mean "which has 27" wheels".

I have the same bike as my touring bike. (http://freeengineer.org/thetouringbike.html) I use 27 x 1
1/4 Conti Top Touring 2000's which are still made and available, and I cruise dirt roads and even
some trails without problem.

I remember there once were 27 x 1 3/8 tires, and I think that is the widest it will theoretically
take. As to where you can find such a tire? I haven't seen any for awhile.

At one time I looked at converting to 700c but concluded it wasn't going to be possible because
of the cantilever brake boss locations. New brakes of some unknown miracle brand would be
required at least.

Conti's are sweet and cheap 27 inch tires are still available at most any wal-mart and the like and
thats a good thing for when you are on tour.

If your original wheelset was anywhere as badly put together as mine were, that is going to be the
weakness as far as dirt roads. The first washboard section you hit without slowing down and they
could fold. Make sure your wheels are true and the spokes tight and you should be good.

Viktor I am a little confused. I can not see how different brakes will increase clearance for bigger
tires. The mounting point of the brakes cannot be changed so a longer brake will make the pads miss
the rim. Sounds like you are looking for comfort. Have the bike shop put on the largest tire that
will fit in the frame. You should be able to fit at least 32's

Most wheel sets are 3cross spoke pattern. 4 cross use to be alot more common. The fourcross spoked
wheels are generally more shock absorbing that the 3 cross. Use the best quality butted spokes you
can afford and have someone with a good reputation for wheel building do you a set.

Harris Cyclery has 27x1 3/8" Tioga Bloodhound tires for $19.95. This is likely the widest size that
your bike would accept and if your wheels are still OK this is a much cheaper way to go. These tires
are described as having an aggressive knobby tread which sounds like it would be suitable for dirt
trails. You can check this out at: (http://www.sheldonbrown/harris/tires/630.html)

Wider tires is easy. I'm not sure why you want wider wheels. You can fit pretty wide tires on even
narrow rims. I use to run 38C tires on a MA-2 rim.

Just get the wider tires and re-user your old rims and brakes.

It's a 27" frame, or 68.5 cm, which is why it's not replaceable. I have one too, which I treasure.

The brake studs on mine are situated such as to work for either rim size.

If his frame is like mine, it's got cantilever brakes. Some earlier C'dale touring frames had
standard reach calipers though.

No kidding. I bought the last one they made when they stopped producing the size around 1991. It's
been an excellent bike with tremendous durability under a lot of hard riding.

If your frame is like mine, and it has cantilever brakes (the kind that mount on 2 posts which stick
out of the frame), then you can fit any 700x38c tire without problems. Some of them fit with enough
clearance for fenders, though that does not sound like it is a big issue for you.

Good 700x37 or 700x38 tires I have used include Continental Top Touring 2000, WTB Slickasaurus,
Tioga City Slicker, Panaracer Commuter 737, and Kenda Kourier. Of these, Contis have the strongest
casings, and WTBs are the fastest.

If you like your wheels and find them strong enough, you will not need to replace them. New tires
alone will do the job.

If you have cantilever brakes, they can be adjusted to clear any tire you use. If you have caliper
brakes, they will dictate how fat a tire you can use before there is a clearance problem.

You can do the tire change yourself, but let the bike shop handle any work on the brakes. You may as
well have them inspect the bike and do other adjustments as necessary.

On the off chance that your bike uses 27" wheels and tires, I recommend Michelin World Tour 27 x 1
1/4" tires. They're significantly fatter than most tires in that size.

I meant what I wrote, a 27" frame. And like most bikes, it uses 27" wheels. As I wrote, 27" frames
are not common.

That's good to know. I probably will never wear mine out then, assuming I don't crash. So, I think I
got lucky, getting a 27" frame when I did.

Yes, it does have cantilever brakes. I should have wrote that. I can use 700x38c tires? That'll
probably work fine. I just want something that feels more stable. You're right, fenders probably
aren't an issue, as I won't be riding in the rain or mud.

I'm too old to worry about being fast, but stronger casings are good.
Mr. Tuffies (do they still exist?) inside are even better.

You can rest assured that I will let the bike shop do the work. In my youth I would try to adjust
brakes and chains, but the results were never as good as a professional's work

Actually I just looked at the bike, and it uses 27" wheels and already has 1.25" tires on it. The
wheels are the original Sun Mistral ones I bought with the bike.

Okay, does someone want to list the standard widths of available wheels? Are there only two widths,
racing/touring and mountain? I guess I assumed that there were a few different widths. What width do
the (I don't know what they're called) half-mountain / half-touring bikes (combo?) use? Remember,
unlike the majority of you here, I no longer care about going fast.

It should be obvious that I am completely out of touch with modern bike technology. I haven't ridden
in years. I will be able to test that old saying about never forgetting how to ride a bike.

The Michelin World Tour at the same price is as wide but not knobby.

I bet you cannot feel the difference between a three cross wheel and a four cross wheel. If there is
any "compliance" going on _within_ your wheel, the tension is inadequate.

Among major brands of spoke there are not quality differences. I agree with using a major brand of
good spoke but Wheelsmith/Asahi and DT and ACI and Union all are acceptably good. Nipples do vary
but that aids or frustrates the builder without otherwise affecting the wheel's perfomance.

Like many things bicycle, there are no standards. There are loads of wheels that are nearly the same
diameter yet are incompatible, 700C
vs. 27" being the most asked about. The half 'n' half "hybrid" bikes use 700 x 38C tires usually-
roughly 1/4" wider tires mounted on rims
1/3" smaller in diameter than your current 27 x 1 1/4" wheels & tires.

Much of the U.S. market has standardized around 700C ("road") rims and tires and 26" ("mountain")
rims and tires in recent years. To make things more confusing, 700C tires are available in widths
from 19mm to
1i (1/4" to 2 1/2") while 26" tires are available in widths from skinny to gonzo (1" to 3").

If I were in your position, I'd just replace the tires that are on the bike, clean it up, and go for
a ride. Life's too short to spend time worrying about your tires.

There are two sizes of wheels (that's the metal part) that will fit on your bike. One is called 27"
and it has a 630mm dia. seat where the tire bead sits. The other is called 700c and it has a 622mm
bead seat diameter. The two sizes of tires are functionally equivalent, but not interchangeable on
each others' rims.

27" rims are obsolescent, down but not yet out. They were that way even in 1990 when you bought your
bike, but old marketplace habits still put them on some bikes in the touring category.

You have said your bike uses 27 x 1 1/4" tires. That size is the widest of the 3 commonly remaining
sizes for 27" rims. But not all 27 X 1 1/4" tires are the same size! I recommended Michelin World
Tour tires because they are the fattest readily available tires I know for the 27" size. I think you
will like them.

If for whatever reason you choose to spend money repairing or upgrading your wheels, replace them
with the 700c size. Your frame will accomodate them just fine, and you'll have a better selection of
wider tires to choose from, like all those 700x38c tires I mentioned earlier.

Good luck, and happy cycling.

More terminology! I would assume that the 'c' in 700x38c tires referred to centimeters, but that is
not possible. 38c must refer to 38mm, so a 700x38c tire is just a hair under 1.5" wide, right? I
really like this option. It'll cost me a few bucks for new wheels, but the thought of having another
.25" in the width appeals to me.

I have a similar type frame from a different manufacturer. I changed to 700C wheels a few years
back. I now can ride 700X40 knobbies, 700X25 slicks, and anything in between. Very happy now!
