I running my old Reynold Carbon Rim brake wheelset 46mm front 66mm rear.

I am considering selling the Reynolds and going tubeless. I am look at Carbon Elite Wheels with 50mm front and 50mm rear.

Besides tubeless, the Reynold are narrow 14mm internal width and the Elite Wheels are 17mm.

Financially, I will almost break even, or pay a bit more once I sell the Reynolds and get the Elite Wheels.

What are your thoughts about this wheelset "upgrade" going tubeless and slightly wider inner width?

I've been running tubeless on my MTB for 15 years and cant imagine ever going back to tubes.

Not a fan of high pressure tubeless (80+ psi)

I changed from an older set of Bontrader Aeolus 5's rim brakes that were 15 internal if I remember to a new version that is 19 internal and tubeless, and even sold my old wheels. I did not regret my decision. Old wheels I generally ran at 100 psi running 25mm tires, now running 28mm tires at much lower pressures, generally 64 to 67. Much more comfortable rides

Can you share what you like about the new set up?

Sorry, you caught me in the middle of the update in my prior post. Wider tires, lower pressures, more comfortable rides were the big hitters for me.

Haven't tried tubeless for road applications but being able to go lower pressure on a wider tire will be nice. One thing to consider is what is the maximum tire width your current frame and fork will allow. I don't think the difference will be huge if you're frame limits you to 28mm tires anyway. The wider modern rims make my 25mm tires inflate up to 26-27mm actual width which still fits my older frames, and that's kind of like what a 28mm tire on a narrow rim is like.

I've been running Road (700c x 25 on 19mm internal) for thousands of miles, awesome stuff.
Not a single ride ending issue. Biggest issue was a pinch flat that had to be pumped 3 times before sealing completely.
I did consider a bacon strip, but it was not a warm day and just needed a little extra time/air to do it's thing.

I'd get wider rims - as wide as will work with your brakes. Check out the zipp pressure calculator and BTLOS wheels. I'm on 25mm hookless with disc brakes. I doubt you'll find that in rim brake.

BTLOS has 19mm IW hooked, tubeless ready rims for rim brakes.

If you get frequent flats, do it and use sealant.

If you do not get frequent flats, don’t bother.

2 thoughts:
1. Carbon rims are great with disk brakes. Not as great with rim brakes.
2. Some people don't seem to care, but I would much, much rather not have to deal with taping, especially at road psi. I would definitely go with rims with no spoke holes, which need no taping. (Shimano, Mavic, Fulcrum, etc make this type of rims)

I went from Mavic Ksyrium Elite clinchers to Mavic Ksyrium Elite USTs about 4 yrs ago. I find tubeless to be easier to spin up, more comfortable and lighter. I weighed them with my Park digital scale. I have tubeless on my 3 bikes and my wife's 2 bikes. We have never had a flat. Just my experience.

I'm a mountain biker as well...tubeless since 2004. Anyway, I recently used ENVE 3.4 SES disc tube-the wheels and some alloy clinchers as well with DT 411s and with Easton R90 SLs. I think 17s are a bit too narrow but I am not sure what size tires you want to use. On the road now, I have started to use 30s and 32s and will never go narrower. They are on ZIPP Firecrests with 25mm internal width. I absolutely love these wheels and I do not like many carbon wheels since I find them to be harsh riding. Personally, I would look at rims that are 20mm+ and use 30-32 but obviously many older bikes cannot fit those. So 17mm rims will work fine with 25mm tires.

Yea this is something to keep in mind. I found my tubed tires seem to go a little wider than my tubeless version on my rims, but on the two bikes I am running tubeless, I have been running Pirelli P Zero Race TLR in 28's on my Emonda and width of the tire running on my 19mm internal rim is 28, but on my Domane that has the 23 internal width, the P Zero Race TLR is running at 31.5 on a 30mm tire

LOVE the Reynolds Assault LE's that came with my Canyon, very happy with the switch to Tubeless. A bit of work every year or two cleaning out the gunk and refilling sealant but overall no regrets...

Lighter wheels spin up faster (and slow down faster when coasting). It has nothing to do with whether they are tubeless or not.

bruce19

This is true of course. But, in my comparison of Mavic clinchers and USTs I was making the point that the USTs are lighter than clinchers and, thus, spin up quicker. That is the connection with your accurate point.
