Well, there were a lotta things said by various 'authoritative'
individuals about my new carbon wheels.


Firstly, and most importantly: *braking is as good as with any of my
alloy rims! *Did a coupla panic stops, and some more gradual braking
during bombing a hill, with an anticipated turn at the bottom type
braking. *Yes, the brakes did require a bit more modulation but
certainly I was able to stop and control braking as well as ever.
Yes, the pads are more spendy (unless purchased in bulkish quantities
on ebay - which I did) but they do work quite well.


Secondly: *no, I did NOT have to correct the spoke line.


Anyhoo, the wheels climb like a monkey, spin up nice and are only
mildly affected by crosswinds (30mm section). *Went for a ride
yesterday in 15 - 20 mph winds and had a great time. *18 degrees
ambient. *God it was great to get out on the bike again!


Sorry (oh, wait, not sorry at all), but you 'nattering nabobs of
negativism' were totally wrong.

Was it wet yesterday?
Did you notice any advantages compared to the cheaper alloy rims? If I
remembered correctly they were on the heavy side.

Lou


The cheaper alloy rims that weigh much more? Yes. To get a rim as
light (390 gms) I have to go to the IRD Cadence. Box section, non-
aero, wimpy rim. Destroyed the first rear I had because the single
eyelets pulled outta the rim with just 105 kgf on the DS in less than
a year of riding.

And to get a rim as stiff, I would have to add 180 gms *per rim* for
Velocity Deep Vees with the same section (actually not as aero as the
aero section on the Protech but the same depth).

So these are lighter than alloy rims with the same section by 360 gms,
and yet as strong as those much heavier rims.

And since I have the coin, I can enjoy the ride. Plus it was a kick
building the wheels as I am an inveterate putterer.

No, Lou, it wasn't wet. But I imagine similar performance from my
braking (i.e., the brakes will have to clear the gunk and water before
they kick in as with a wet alloy rim). And I will be wary of the wet
until I have proven otherwise.

Not persuaded yet. And if you do turn out to be right, Lou, well,
then I don't ride them if it's gonna rain. Generally don't ride in
the rain anyhoo, if I can help it.
