Anyone running Hutchinson Sector tyres and do they fit the Vendetta?

[KiwiGuy]

I've decided on using Pacenti SL 23 tubeless ready rims built up with White Industries T11 hubs for my Vendetta.

After an experience yesterday (I'll elaborate below), I'd like to run Hutchinson Sector tyres. These are 28mm tyres, but apparently measure 28.5mm wide on the Pacenti SL 23 rims.

Does anyone know if these tyres will fit on a Vendetta at this width?

As to the reason I want to run this set-up. I've been tossing up between the Pacenti rims (which are tubeless ready and reasonably aero) or a wheelset built with Rails 52s (which are super aero but not tubeless).

Yesterday I rode 'The Rev'. A 100km road cycling event with a little over 900 metres of climbing through beautiful country in the centre of the North Island of New Zealand (it passes by the famous Hobbiton). I haven't yet upgraded to a Vendetta, so rode it on my 2005 steel-framed Volae Club. Even though I rode it as a benchmark event so that I could compare the time against riding the same event on a Vendetta next year, it was a frustrating experience. Because the bike doesn't climb well, I was well beaten by df riders I can out-perform when I'm riding a df.

That aside, I was reminded how coarse the rough chip seal is on our rural roads. It generates a lot of vibration, and rolling resistance, with the 650c 23mm tyres I currently run. I concluded that with the move to a Vendetta, using wider tubeless rims with wider tyres (and hence lower pressures) would be a smart way to go. If I'm in a paceline I don't need the marginal additional aero of deeper rims. What I need is low rolling resistance and less vibration.

I was already considering running 25mm Schwalbe One tubeless, but after this event the Hutchinson Sector's look even more attractive. If you've had any experience with these on your Vendetta, I'd love to hear from you.

Kind regards...

Just measured the clearances

Just measured the clearances on my Vendetta 1.5. I'll leave it to JT to confirm any differences to the V2.0.

Tightest is the front of the fork crown. Without removing the brake I cant get a caliper in there, looks tight might be 5mm or even less. I have 23mm Vredesten Vortezza tricomp tires.

Rear of the crown is 7mm clearance.

At the bridge below the bottom bracket it's more than 11mm clearance

At the two bridges on the rear wheel stays it's 11-12mm.

So a fatter tire than 25mm on the front probably is going to be very close. 27mm might fit with very marginal clearance.

On the rear the 28mm will fit no problem.

All these clearances are radial. Will measure width clearances tomorrow.

Thanks Hamish

Thanks for posting these measurements Hamish.

It looks like running 25mm on the front and 28mm on the back might work. Pretty tight clearances in the fork crown area!

Kind regards...

25mm will fit but the

25mm will fit but the clearance is close as noted. Some tires have a rounder profile than others. Provides a smoother ride than 23's however, so that is a plus.

This is a V-2.0 drive wheel

This is a V-2.0 drive wheel with Hutchinson Sector 28 tire mounted on a very wide 21.3 mm inner width Industry Nine tubeless rim. It's close, but the photo makes it look very close. Since this combo fits, pretty much any rim and 28mm tire should.

Thank you

Hey BentAero

Thanks for posting. The Industry Nine wheels look very sweet. And that inner width is wide - presumably with a 25mm outer. I definitely think that's the way to go.

It's great to know that the Sector 28 fits even with such a wide rim. It'll work for me.

Kind regards...

Tight tire clearance

There is a risk associated with very tight tire clearances (voice of experience here). While not a high probability, if a bit of gravel/mud/twig/rock/asphalt gets picked up by the tire and carried up to the fork, you can have an immediate halt in wheel rotation with pretty spectacular results.

With clean roads and dry pavement, this isn't much of a risk, but with rain or wet pavement and sticky mud, the risk is very real.

I'm a big fan of bigger tire sizes, but there are risks when you are pushing the limits of clearance. 'Nuff said.

I will echo Ashtabula's

I will echo Ashtabula's comments. Running super tight tire clearances can be a hazard. I have never experienced a wheel rotation halt but I have seen some pretty demolished tires from debris getting caught.

I apply this to doing fender installs as well.

Excellent point

Hey Ashtabula

You make an excellent point, of which I've very mindful.

A few years ago I bought a Specialized Roubaix and discovered that I couldn't run 25mm tires on it for that very reason. Any stone which stuck to my front tire would end up jammed between the tire and the underside of the fork. No damage to the tire but lots of superficial damage to the carbon fiber fork.

Kind regards...

Not sure about Sector s but my dad fell off his 2007 Specialized Tarmac doing Cycle for Life in South Auckland and broke every bone in his body so I bought a pair 28 mm GP4000S2's which spun without rubbing but there was absolutely no daylight between them and the top of the frame. So recently I bought 28 mm GP5000s and they are substantially smaller with plenty of clearance. I could probably put 32 mm GP5000's and have room to spare.
