I feel obligated to post that the Topeak Valve extenders that Performance Bike sell do not fit in the rim hole on either the Flo 60 or 90s. Not a huge deal but I didn't realize the end that they didn't fit and thought I'd pass on the info. I ended up going with the internal valve extenders as recommended.

Just a couple of replies to earlier queries in this thread.

Tyres: I have mounted Michelin Pro4 Service Course tyres and they were a bitch to get on. I've previously used Schwalbe Ultremo tyres and they were much easier.

I run Michelin latex inner tubes and, like an earlier poster, I was concerned about the valve cores not being removable. Vittoria sell a latex tube with a removable core (actually I belive Michelin are discontinuing the latex tubes, so I'll have to look at the Vittorias if I run out - providing I can get the Michelin tyres back on without blistering my thumbs again). However, since I already have a small stock of the Michelin tubes I looked for a solution - I didn't want to use external extenders because I travel by air with my bike quite regularly for triathlons so wanted to be able to deflate the tyres easily. I bought the Topeak valve extenders from Performance Bike which cleverly connect to the valve core below - so you can open and close the valve, and deflate as if you had an internal extender.

I can confirm to my cost though, that they DO fit through the hole in the Flo90 - see my post on the FAQ forum when I lost one in the fairing! However, it is a very snug fit and they won't go through if the hole in the rim tape is not 100% lined up with the rim hole. Also, the Michelin tubes ship with a transparent plastic sleeve around the valve - it helps to take this off before putting the valve extender on.

Hope that's helpful!

What is the required total valve length for FLO 30s?

Good question. A 48mm valve length works great.

Take care,

I plan on using a tube with an 80mm valve on a FLO 60. I was wondering if this valve length will fit in the disc so I can carry just the one spare tube?

henrybeagle,

Unfortunately, the 80mm valve will be too long for the FLO DISC. 48mm tubes work great for the FLO DISC.

Take care,

Howdy folks -

I finally have the setup dialed in for my '14 Scott Plasma 20.

FLO 90 Rear - Conti GP4000Sii 23mm, Vittoria Latex 51mm removable core valve, 60mm Conti Valve Extender

FLO 60 Front - Conti Attack 22mm, Vittoria Latex 51mm removable core valve, 30mm Conti Valve Extender

Important note: You CANNOT run a 23mm GP4000Sii in front. The width of the FLO rim not only widens the 23mm tire, but does nothing to "shorten" the height of the tire. You'll get rubbing in the top of the fork. Ask me how I know.

The 22mm Attack is perfect however, since it is now "stretched" to fit the wider rim, the net effect is the vertical height of the tire is now shorter and there are zero rubbing issues.

Enjoy!

I hope that helps.


I would say that neither the GP4000S or the 4000Sii were all that difficult to seat on my 60/90's.

YMMV, but it wasn't a big deal.

cvette4,

I'd still recommend the 52mm tubes I mentioned above for the FLO DISC. A 48mm tube is likely more common and that will be perfect as well.

Take care,


Just checking in here, just ordered up a Disc and FLO 30 front and rear. Will a 51mm presta valve work fine for the disc? Do I need a crackpipe or other adapter?

Also, is there a recommended valve height for the 30's? I may just stay standardized on the 51mm Vittoria Latex tubes if I can.

Thanks!
