Covering the valve access hole of a Flo disc wheel

Postby William » April 27th, 2017, 9:50 pm

Hi guys,

I'm currently racing time trials on Flo wheels, and like any other tt rider am looking for any aero gains I can find that comply with the UCI rules that I race under.

One thing I would like to do is to cover the valve access hole in my Flo disc wheel to clean up the air flow, and this is legal but has a significant restriction:

"...the valve access hole of disc wheels that may be covered provided that the cover used is supplied by the wheel manufacturer (and no other party)."
http://www.uci.ch/mm/Document/News/Rule ... nglish.pdf

What I need are stickers (or better yet a roll of 2" tape) showing the Flo logo to cover the access hole on raceday once the rear tyre has been pumped up.

Hope you can find room in your product line for this,

Cheers,

William,

Thanks for writing. I've never heard of this rule. Everyone we have dealt with in the past simply uses clear packing tape or 2" wide electrical tape.

What if you used a cover by another manufacturer like the following... http://www.wheelbuilder.com/valve-cover-patches-for-aerodisc-cover.html

Would those work for you?

Hi Chris,

No unfortunately the valve access hole cover has to be sourced from the wheel manufacturer (i.e. Flo) or it's not legal under UCI rules. Stickers bearing another manufacturer's logo aren't going to cut it because the scrutineer will immediately know that they've been sourced from a third party and therefore don't comply.

I considered buying some of the standard logo stickers to use (manufactured by Flo for this wheel so they pass the test), but unfortunately they are too narrow to cover the hole.

While I realise the performance advantage is small (http://flocycling.blogspot.com.au/2016/ ... utout.html), time trials have been lost by two seconds before and will be again, so it's really quite frustrating to be unable to fix this problem.

Regards,
William Russell

William,

I'm sorry to hear about that. I just went to my garage and tested a few things out. Our new model FLO 60/90/DISC stickers are wider than the old 2012-2015 model stickers and will cover your valve holes. They have our logo on them and could be used. Here's a link to that item in our cart: http://www.flocycling.com/store/index.php?route=product/product&product_id=158
