[net.bicycle] Bicycle Frame Tubing and Slick Tires

bhilden@druhi.UUCP (HildenbrandBE) (10/10/85)

Regarding Columbus/Reynolds tubing comparisons I seem
to remember the following figures.  For a 23" frame,
a tubing set of each weighs:

	Columbus SL	2000 grams
	Reynolds 531	2300 grams
	Columbus SP	2400 grams

So, I would say the 531 tubing is more like SP than SL.

About "smoothies", I don't know what the big deal is
concerning if the hold in wet and/or dry conditions.
I ride Specialized Touring II's and after about 300-500
miles the tires have zippo tread pattern left.  I ride
the suckers until the nylon cords start poking through.
In Colorado we have rain soaked roads on fast downhills,
the only problems I have experienced is hydroplaining
right after a rather large downpour(I suspect any tire would
hydroplane under these conditions).

I guess my point is that unless Avocet and Specialized
are using a wierd rubber compound, the lack of a tread
pattern should not make one(1) bit of difference.

p.s. - outside of aerodynamic equipment(Disk Wheels, rims, helmets)
the only way I have found to really increase performance of my
bike is to train harder:-)!!
