Cycling Forum / General / Technical / March 2007

A friend was looking at the current thread about standing-start
downhill coasting tests.
He asked me whether the mass of the tires would make a difference.
I cleverly replied, "Huh?"

Since ISIS bottom brackets suffer from durability problems of the
bearings due to their small size, would harder, more durable ceramic
bearings be the cure?
A company called Token makes ISIS ceramic bearings.

It's time for me to replace my current Ultegra 6500 crank set and
bottom bracket. I have been using this setup for several years now and
was thinking of going to the new series Ultegra 6600 set. I have
checked the weights and do not see much difference in that area. Is

I am looking for a small (not frame) pump for the road bike. I want one
that will mount under a water bottle cage. It looks like my choices are
Zefal Double Shot and a few Topeak models. Anyone want to chime in?
TIA

I am considering buying a pair of 10 yo Shamal clincher wheels for an
older bike , which of the current campag wheels would be the equivelant
model to the Shamal , ie is it the equivelant to Eurus etc (allowing for
the age of the wheels)?

I have 1999 Campy Mirage 9 speed levers on my bike.  I am considering
buying a new set of 2006 Mirage 9 speed levers as a backup.  I see
that the 2006 levers have the black plastic paddles, but other than
that, are the levers the same in terms of parts and function?

Can any one speak about performance of the Specialized
Mondo Pro 622 x 25? Cornering and ride in particular.
I was surprised to see a slick tire that is not an
Avocet. The SMP is totally slick; no file pattern even.

Is there a cheap method for sealing areas of paint that have flaked
off on an aluminum frame?  I own an 87/88 Trek 1500 road bike and
after cleaning the fraime this morning discovered areas where the
paint has flaked off exposing upwards to 1.5 inch square.  The bike

Now that Shimano 7800 kit has been out in the market for, what, 3-4
years at this point, I'm wondering what the consensus is as far as the
durability of the consumables (rings, chains, cassettes) and the DA
shifters.  Any difference when compared with DA 7700?

I was just wondering what you all thought about the different degrees of
float fir the look style cleats. I have 9 degrees of float with the cleats I
have now and was wondering which is better the ones I have now or the 0
degrees of float cleats. any help would be great. thanks

Back in the old days (1970-80) when I used tubular tires, they all
seemed to have latex tubes inside. This was supposed to be more puncture
resistant but they tended to loose air pressure overnight (or so).
I have some NOS tubular tires I wish to sell and have been asked if the

No.  Not bladed spokes or low spoke wheels.  I mean wheels with fancy
spoke patterns like crow's foot, etc.

Seems like there could be issues, but I know jack about wheel building.

My touring bike has a 12V power system, powered by a dozen C-cell
alkaline batteries.  So I decided to add a car horn.  But to my dismay
the car horn pulls 4 amps, more than my battery pack can handle, the
horn will not even go beep.  I guess alkalines have too high of an
