"Deep V Rims"...pros and cons?(5 posts)

"Deep V Rims"...pros and cons?MVN
Sep 29, 2001 11:36 AM
I just bought two Velocity "Deep V" rims (Australian made) for my new Trek bike. Trashed the original front one in a parking lot (fell into a concrete crevice, lol), so I called my LBS and he said that was the only thing he could find in my price range. He tried to get originals from Trek, but they didn't have any left. I'm not a racer, and I can't afford several hundred bucks for new rims (these are cheap by comparison). I just wanted something sturdier. The original rims were short, whereas these new ones are tall. Since I'm new to road biking, I'm wondering about the differences if any. Are there pros and cons to deep V rims? Just curious. Thanks for your time.

The deep V's are very strong and stiff rims. They should be close to indestructable if your wheel builder knows what he's doing.

The only downside to these rims is that they aren't feather lite. You can save about 100gms per wheel by using the aeroheads which are not quite as stiff or aero. I use the aeroheads and find them to be a good wheel also. I'm only 145# though.

You got good wheels.... now stay out of the bear pits ;)

There are a lot of variables to consider... the depth of the rim, the profile of the deep section, the spoke count (and shape), the intended use, etc.

Generally, the con is that they may be heavier than a comparably priced low profile or box section rim and they might be a bit harsher... the pro is that they may be more aerodynamic above 20 mph and they might be a bit stiffer, but again, there are too many variables at work to give a definitive answer.

The Velocity Deep is a good rim and will probably serve you well, especially since they are allowing you to continue to cycle. My personal wheel choices run from CXP 21's to HED Stinger, ZIPP 404 and disc wheels... yet the most valuable wheelset is the one that allows me to get out and ride.

I finally wore out the rims on my old (real old, lugged steel) Allez, and had the hubs laced to Deep V's. They've stayed absolutely true for a couple of years, never a tiny wobble. But I DO feel the weight (520 grams for the rims, I think I read somewhere) when I accelerate. I'd buy 'em again, though.
