[NMCycling] Road tubeless

Fri Jun 27 14:16:38 MDT 2014

Interesting discussion!  I have been running tubeless on my MTB for about 8 years so I am very familiar with the various issues there, but I am wanting to try tubeless for road.  I am running Mavic SSL's for wheels and, while the rims are not drilled except for the air valve hole which would make them ideal for tubeless, I have heard that the Mavics don't have enough of a "keeper" lip on the inside of the braking surface to safely hold onto a tubeless road tire.  Does anyone out there have some insights to my particular situation?

Cheers,

John Jordan

curious what rim you have those intensives on that it measured 23.8 mm?

mine are on stans alphas and they measure a 0.97-0.98 (~24.7mm) near
    as i can get with my calipers.

only complaint with the intensives is that they take too long to
    wear out.  i have a set of the sectors i have been waiting to put on
    after the intensives are done and i can't wear the dang things out.

bought a set of intensives in may 2011 and then another set in late
    2012 when i thought the 1st set was about done.  but, no, they just
    keep going.  finally wore one out and got a bad enough glass cut
    that i couldn't repair the other one.

still waiting for the final two to quit.  that glass cut is the only
    flat i have had in 4+ years of riding this system.

fwiw i ride these tires lower than typically recommended (55 front,
    70-75 rear) and find the ride to be pretty nice although i am sure
    it is not as nice as the 28mm sector and probably more sluggish than
    at higher pressure but the corner amazing.  hit a 1" or more thick
    steel plate when i was coming down rabbit ears pass at something
    close to 50mph.  didn't see it until the last minute, no time to
    unweight, slammed it with those tires and alpha rims and no pinch
    flat, no rim damage, no tire damage.  they paid themselves off in
    that instant.

I also run the Hutchinson Sector 28’s.  They are my go to tire now.  Very light at 280 grams for the tire.  Not a harsh riding but very comfortable tire and they handle amazing.  Mounted on Easton rims the tires only measured to 26.5mm.  Mounted on a Stan’s Alpha rim they plumped up to 28.7mm, I thought they handled good on the skinnier Easton rim.  To my surprise they handled better and felt more comfortable on the Stan’s rim.  

The Hutchinson Intensive was a promising tire, at 25 mm.  Overall it was a very harsh riding tire than measured at 23.4mm.  They did last a long time though.  The Fusion tires are also very narrow and harsh riding.  The casings on the Intensives and the Fusions seems much stiffer than that on the Sector. 

Some friends have been riding the IRC tubeless tires in both the 23mm and 25mm widths and they have a very good ride.  The 25 was more like a 27mm tire.  

Sure do wish that there would be some offerings to come out of Michelin or Continental.  Just to see how they compare.

I really like the Hutchinson Intensive Tubeless, I think they are all 25mm. Fusion 3s are a little softer and racier.

I have the Hutchinson Sector 28’s on my cross bike for road and gravel and running at 75 psi.  The are great for rough roads, gravel, etc., but if you are concerned about going fast on nice pavement, I would probably be looking at 23 or 25 instead.  The 28 is nice, but you give up a bit in aerodynamics and rotational weight is noticable.
