So what happened to using a set of winter wheels / rims (your "training

wheels"). When they wear out in a couple years, simply tape a new rim

beside, and transfer the spokes. Takes 1/2 hour. If you don't know how

to true a wheel take it to a shop at this point. You can always finds

cheaper and heavier rims for less than $20. Some rims have a thick

section on the rim specifically for brake wear with "wear" indicators.

Obviously you want to pick a rim that has the same erd. Use Spocalc

database for this by (Damon Rinard) on web... see sheldon brown.



Also get the brake pads that "clean" the rim first before full pad

engagement. Ie the have a little scraper out front. Koolstop has them.





Much cheaper and easier than disc brakes.

Some feel that you don't get much better stopping power no matter what

color of Coolstop brake pads you use.

Others feel that any color, other than than the green, yeild better

stopping performance but the other colors wear out faster.

Some have only used Shimano D/A black and have been satisfied with that

pad.

There was a recommendation to toss the rain bike for a cross bike type

commuter with disk brakes. However, that's a bigger investment, yet my

life might somehow be worth $1,500 bucks. :)



Thanks all for the input.

I had a set that I used for 20,000 miles and they looked as good as new

when I got rid of them. No type of brake pad seemed to hurt them, but

unfortunately, no type of brake pad seemed to give any stopping power

when wet either.   I finally got rid of them after nearly running into

the backs of cars a few times while going downhill on a commute to work

in the rain. I now use disc brakes on my commuter bike.

Subject: [OBRA Chat] Ceramic rims questions







Has anybody got experience with ceramic rims? I'm using a set of Mavic

Open Pro Ceramic rims on my rain bike (because regular aluminum rims

just get wasted on the braking surface because of all the grit). I'm

using the Coolstop green brake pads (for ceramic rims) and they work

fine in the dry but don't stop very fast in the wet at all. Has anybody

used the regular Coolstop (black) brake pads on ceramic rims? Do they:



1. wear out really super fast

2. work at all

3. stop faster than the green ones in the wet

4. harm the ceramic braking surface

Or anything else?



Sorry if this is on topic... ;-)

I've used those rims with the shimano d/a black pads and had good results.



that said I will go through maybe 2 pair of pads per winter.
