Disc Cover on zipp 404 / Speed Concept

Triathlon Forum
1

Long story short. i have zipp 404’s with a PT laced hub. i recently purchased a used 2014 trek speed concept 9 series. went to set up my disc cover for Silverman and found out that it rubs and that won’t be an option. i am changing my power/wheel set up over the winter so this won’t be an issue next season, but i am racing IMAZ in about 5 weeks and i was wondering if i would have better luck with my buddy’s catalyst disc cover (built for his 808), or would that not even be an option since it was built for his 808?

thanks,

try making a DIY disc cover. Because it’s “custom made” from two pieces of flat ABS
plastic sheets the curvature will be perfect and won’t rub.

Your buddy’s won’t work because it’s cut to fit the somewhat deeper 808.

Take the grommet out of the speed sensor blank.

tried that… still rubbed pretty bad, but at least it wasn’t rubbing on rubber.

Did you tape the non drive side cover to the spokes? That is what I had to do when I had a Trek SC…but it didn’t rub

I have a 2011 Speed Concept and a 60 mm rear wheel that I was thinking of trying a cover on. What size is your bike? I’ve heard some sizes don’t work at all but larger sizes might work in some cases.

Did you try Wheelbuilders for a rear disc cover for your wheels?

This wheel builder cover was made for the generic set of power tap wheels, then i got these 404’s and cut the cover down to fit. at Vineman this year i did tape the side with the cassette on it to the spokes with electrical tape because it was wanting to rub a little when i got down in my hardest gear. the tape worked ok. and yes, i did try to tape the non drive side to the spokes before Silverman, but this side of the cover ‘pops’ out a little more in shape, so when i try to tape the cover to the spokes i get about half way around and as i tape a spoke it pulls it off the spoke opposite of the one i am taping (does that make sense). did you maybe use a different type of tape that holds better? i think that at least sounds like it’s worth trying!

Red X - my bike is a large frame.

thanks for all the feedback guys. hopefully some stronger tape might hold to the spokes a little better. i’ll let you know if i have any luck with that.

There is a problem with the speed sensor rubbing on wheel… some seem to have ways to get around it, removing the sensor/grommet, taping the cover, etc. but Wheelbuilders lists the Speed Concept as one of the few that does not work with their cover.

Weird. I have an Enve classic 66 mm rear wheel with a power tap and Wheelbuilder cover and it’s no close to rubbing. Bike is a 2012 Speed Concept 9 in size XL

Got a diy cover and tape the drive side with duct tape and the other side with Velcro (tape behind the spoke and Velcro above) scotch3m 33 all the way around the rim. No SC though.

check out catalyst wheel covers. i purchased one a while back and it has been awesome. easily taped on and i’ve run it all season without any re-taping. it’s a lot lighter than the wheel builders cover and i personally like the look of the carbon vs the plastic.

well, i dont really want to spend much money, because after this race i will be changing my power/wheel set up and this won’t be an issue anymore.

sort of off the subject - any ‘quick math’ on how much time i would be giving up if i just ran my normal 404’s vs. using the disc cover at IMAZ? my FTP is 242, i did vineman at an average of 200 and completed that bike in 2:31 (with disc cover on a 2011 felt B16). i am shooting to hit 180 average watts at IMAZ and thinking about a 5:25-5:30 bike split.

thanks!!

Seen em but to get them shipped to Germany makes em kinda golden after customs, that’s why I decided to make my own out of curv material which I can get over here.(kinda carbonish lookin)

Any idea where one can find fault ABS sheets to use?

Thanks

I’ll have to look for the name of the company I used when I get home.

If you have a PT, then there is no need for a separate speed sensor since the head unit can get accurate speed info directly from the PT.

Thanks so much…

click on “sheets other sizes”, get 0.030 in a 24X48 sheet. cut it in two and there should be enough
for one wheel if it’s not a box rim you are working with.

Hey man, thanks so much! I appreciate your help. I’ve got one that doesn’t fit my frame because of the curve, so maybe my own flat one will work better.
