Subject: looking for a disc

I'm researching disc rear wheels for next season.

I just can't afford/justify a Zipp or similiar, so am looking into cheaper options new or used. The new Renn 555 at $795 looks pretty good - what else should I be looking at?

A disc cover is the other option, I suppose. My current training/race wheels are Ksyrium Equipes, which seem good all-rounders. I'd be reluctant to have to keep taking the covers on and off.

Any particular discs that you would warn me away from off the bat?

A cover is the way to go as far as cost efficiency goes. You get 99% of the benefit at a fraction of the cost (although you lose the "whoosh" sound effects)

 

Flo's, Renn's, used Zipp/Hed's are all good options

Wow, flo disc at $599 - thanks for that - certainly worth considering from the price point of view!

It might come to a cover on my existing wheel, but I like the option of going with a regular wheel if the weather/elevation warrant it, without having to fiddle about putting the cover on and off. And if I bought a wheel specifically for the purpose, then I'd be halfway to a dedicated disc anyway?

I ordered a cover from Wheelbuilders for my Zipp 404 rear. It's really not that big of a deal to install or remove it, perhaps 10 minutes or so. (1st time did take a bit longer) I'd sure like to have a "real" real disc, but it provides nearly the same benefits as a solid disc for a fraction of the cost. I have noticed that I do get a touch of rubbing on the cover from the chain if I'm in the largest ring in the back. You will just need to confirm that they make a cover for your specific wheel...use their website for this. It will cost you about $90. You will need a chain whip to remove your rear cassette...they can sell you everything you'll need from their website. You can also find pretty good prices on older HED disc wheels...I've seen them as low as $400. Just be sure it will support your cassette. Most new cassettes and rear derailers have 10 gears...some older wheels had 7, 8 or 9 gear cassettes. I don't know the implications of trying to make an 8 gear cassette work with a derailer that is expecting 10 gears....I'd guess you'll have lots of shifting issues. My profile pic shows me riding with my disc cover...from 10 feet it looks like the real deal...get close (when I'm passing you! and you'll see that it's just a cover.)The cover is a good, not perfect, but cheap option for some additional speed....and the "cool kid" factor!

In reality, do you take your wheel cover off ever?

Have you ever felt that the race day weather conditions, or the course warrants not going with disc rear? These are also my training wheels, so I would potentially end up training with a disc on - not a big issue, but would definitely look like the tri-geek!

If I had a disc cover, it'd be off for training, group rides, commuting (need to secure the bike with a U-lock), that sort of thing.

I have a cover and I only put it on for races, it is a simple process.

For the cover rubbing the chain on the largest cog, duct tape the cover to the spokes will help prevent this. It works for me, anyway.

Thanks, enough folk seem to be giving wheel covers the thumbs up to seriously consider it. I need to check for 5mm spacing between large cog and spokes, though tbh, I have not ever changed up into the top 2 gears *ever*!

I only use the cover for race day, the easy "pre-race" ride the day before...and one ride 3 days out to insure everything is working as expected.

I do 95% of my training rides on my Zipps as well...while I do still have the R500 wheels that came with my P3, I just prefer the feel (and look...I won't lie!) of the tubular Zipps to my clincher "training" wheels. I'd feel kind of silly using the disc daily.

As for race conditions....from what I know and understand, there are not really any conditions to not use a disc...except perhaps gale force winds! Much of your weight is over that rear wheel, and it does not turn, thus, it does more cutting through the wind that letting the wind push you around. NOT so with the front. My 404's seem to have a profile that works well in higher winds where you'd not want to have anything deeper, like an 808 or 1080 profile. They are also fairly light wheels, so hills are not an issue either. Overall, these are great wheels. I purchased them locally via Craigslist. They are from 2009, dimpled, but pre-Firecrest. Got them for well under $800 including skewers, pre-glued tires (which I've since worn out and replaced) and an Ultegra 11-25 cassette (Which I've swapped for an 11-23.)

Oh, "tri-geeks" ROCK!!

Yep, thanks....I've tried the duct tape too...it does help, but I still had a touch of rubbing. Not enough to toss it out or to worry much about. My last race was a sprint with lots of rollers so I knew I'd not be in my largest cog so I didn't worry about it at all....Certainly did use that cog at the Vineman up Chalk Hill! Laughing

I have a Renn 555 I bought last season. I put 256 miles on it. It is the tubular version. I'm looking to sale it and the tire i was using if you end up still wanting to get a disc. It's been a great disc. I just want to go to a deep rim instead, to match my front wheel.

What's the difference in a flo 90, flo disc, and a flo 90 with a cover? May seem like a silly question but I was under the impression a flo disc is basically a 60 with a cover? Who rides their race wheels and doesn't use a disc? I'd like a 60/90 front and a disc rear but if they're the same thing why not get a 90 rear and cover?

To the OP....what type of wheels do you have now?  The Shimano R500, which comes standard on many bikes, is not compatible with Wheelbuilder disc covers.
