Neat! I also like the last post on that page: "Jan Heine, Editor, Bicycle Quarterly says:
November 6, 2015 at 12:16 am

Both wheels use 6-speed freewheels. For mud, fewer cogs means less clogging. I rarely use more than 3 or 4 gears in a ‘cross race anyhow."

So, according to some, Less really is better than more.

Cheers


For Jan, old is always better than new -- that's his business model. He also says his old Alan is just as good or better than the modern CX bikes, which is spoken like someone under 170lbs who doesn't have to do a lot of braking in mud. On a CX bike with cantis, you start braking at the top of the muddy hill and hope you have some braking left at the bottom. With discs, you can effectively brake later in the hill and go faster, worrying only about traction. Also, his Alan has bar-ends, which are great for auto-shifting when you dismount or hike-a-bike. I'm amazed hes not riding steel, which is by far the most magical substance on earth besides vinyl LPs.

OK, good points all.
But to win at UCI Cyclocross nobody has to beat _you_ to the
finish, merely the other pros who show up at the start line.

Yes, and I rode a flat circuit race in a pack with a US pro rider who was on a three speed just to make a point -- until he got kicked out for riding a three speed. It was good he got kicked out, because he would have crushed me in the sprint.

BTW, Hennie's Cinelli 1R sucked, too. I had real difficulty keeping mine tight, and that seat post . . . pretty, but I didn't usually carry open-end wrenches, and it was so easy to mung the flats. An SR Laprade was a better bet for a quarter the price, and less mung-able (but not pretty). But I'm sure the historical re-enactors would totally dig those things, and that's fine. It's part of the business model for my LBS. http://www.burlingamebikes.com/the-classics/

We both eschew Cinelli 1/R, brother. I never understood the
appeal; it's so darned Rube Goldberg.

Why'd he get kicked out for riding a 3 speed? Was it the handlebar?

I totally agree with you mate, thanks very much! I think it would all depend on one's strength. I usually go uphill with a fixie coz I had no choice..lol

But I'm at a disadvantage during a race coz it eats alot of my energy during the bike leg and will not have enough left to run. But I love my set up so I'm sticking to it than a normal road bike. I just need to modify a few things.

So putting a front derailler is possible correct? So I can install double chainring.


Though it may cost a little in weight, there are 2 speed IGHs that
eliminate the need for extra chainrings, derailleurs and gear levers.

Hello Guys,

I have set up a time trial bike single gear its very fast 50t
chainring and 14t rear. However, the new ironman race route in my
location requires crossing a bridge with obviously inclined slope. I'm
used to going uphill but it burns significant amount of energy. Btw,
the new route has 3 loops which makes it a little disadvantage on my
part going up and down the bridge 6 times. Having experienced this, I
was thinking maybe putting a double chainring like 52t & 36t with
front shifters would decrease the tension for the climb? Do you think
this is possible? I'd appreciate your input.

Thanks!
Max


There's one path to do fixed gear change:
http://www.sturmey-archer.com/en/pro...ail/s3x-silver

Any other option is overly complex, unreliable, possibly unsafe or (as
with a two-sided wheel) ungainly.

If that's what you need, the SA S3X, or vintage ASC,* suits perfectly.


The 2 speed has "kick shift", so doesn't even need a gear lever!

I don't know and haven't looked at the rules. It could have been the ringy-bell. He probably just ****ed-off the district rep who was (and is) a character herself. It was at weekly race at the local racetrack with a giant pack. You can just sit in the middle and get pulled around. That was the point he was making.

I really don't think that modern CX bikes are any better than they were during the time of Alan and Vitus. Bar ends are cheaper and when set up properly are just as good as brifters for this sort of riding.

The new Colnago seat posts are really great. You have a finger adjust for angle and one lock allan bolt.
