I'm looking for a new commuter bike (go to work, go to church, get
groceries - in short, to the extent practical, displace my car).
I started checking out my LBSs last Saturday - lots of really nice
gear. My birthday is next month, so I'm aiming for a purchase in the
latter part of March.
Anyway, I'd like some opinions on a couple of things that LBS guys
have told me.
1. 28 inch wheels (okay, 700s) are much better than 26 inch wheels if
you want to cover more than a few miles. Given that there's only
about 7% difference in circumference, this seems like a stretch to
me. Any experience, opinion, conjecture, FUD?
It's not the wheel size. It's (a) the typical tires used for each size, and
(b) the typical road geometry of a 700 versus the typical off-road (slower)
geometry of a 26 inch. The tires can be overcome in one direction -- you
can put high pressure, narrow slicks on a 26 inch, but you can't put
knobbies on a 700 (frame not wide enough, usually).
Personally, I ride 26 inch wheels in the winter with wide tires, for several
reasons.
First of all, it's dark a lot. There are plenty of things to pay attention
to in the dark. As a result, I'm more likely to hit small potholes, road
cracks or other minor things. A wider tire can handle these easier.
Second, a 26 inch bike handles studded tires much more easily (because these
are wider).
Third, I hate changing tires in the cold and dark. More rubber = fewer
flats, ceteris paribus.
You are quite correct that riding a road bike would be faster. Life's full
of tradeoffs. My tradeoffs aren't necessarily the same ones you'd make.
Quoted message said:2. Disc brakes are way better for stopping in the rain. This seems
plausible to me. I've never had disc brakes on a bike. Comments?
A final question:
3. I hope to ride in the winter (that means -40 windchill and snow
and such). I like the idea of an internally geared hub to keep as
much [censored] off the gearing as possible. Are really cold temperatures
likely to cause problems (grease freezing, for example [it happens on
cars here])?
See "derailleur freeze" thread currently on this newsgroup -- or ask on the
icebike list (via www.icebike.com). I have no direct experience, but I do
know there are dissatisfied winter internal hub owners. As Zoot says, if
it's the cable that's the problem, an internal hub won't help.
The icebike site also offers some hints that at -40 you might want to
replace grease in the bearings with oil; it doesn't get that cold in Chicago
(all-time record is -26F) so I've never tried this.
