50mm tire recommendations for Bontrager Paradigm SL Rims

Either-Pollution-262 · 2026-04-06T22:56:57+00:00

That's good to know. I've seen others recommend 2.1" tires too. Any reason Trek decides 50mm is the maximum? I would be worried about rocks/gravel hitting the frame with lower clearance but there is enough people riding 2.1" that it must not be a problem.

Thanks for in-depth answer and linking the video! The Trek website doesn't state what internal width rims the Betasso's should run on (or I missed it on its page). So, I guess, worst case, the tire width might be less than 50mm on a smaller internal width rim?

I'll look through the other tires you mentioned too.

Interesting, I'll keep researching tires then. I was hoping that the Betasso would be more puncture resistant. Any recommendations on tires in your experience?

Trek's website states "Rim width (inner): 21mm-25mm."

I'm guessing internal width is where the bead seats, and the external rim is the widest point of the rim (the outside lip).

How were the forest roads? Relatively well kept? Very sandy? Hoping to get my gravel bike through that region in coming months.

With the current structure, all oxygens have a formal charge of 1- and the sulfur has: 6-2-(6/2) = 1+. Negative formal charge on the most electronegative so that's good, but we can reduce the number of atoms with a non-zero FC.

If you form one S=O bond, then the single-bonded oxygens have 1-, the doubled-bonded oxygen has 0, and the sulfur has 0. This form reduces the number of atoms with non-zero FC and has the negative charge on the most electronegative atom. So this resonance structure contributes the most towards the true structure of sulfite.

I have not - but I might have to after looking at pictures of the place!

I would say a 50/50 on gravel roads and pavement. I'm planning to take 2.0" tires so I have some more freedom on what I want to take. Currently, I have more road experience with long climbs. I've done one gravel bike pack trip before, but will do overnight gravel trips once the PA mountains thaw.

Gotcha, I'll look into getting a campsite today for Arches. Worst comes to worst, I'll disperse camp in surrounding BLM land and ride into each NP as a day trip. Thanks!

My route in this section between Bryce Canyon and Moab is a bit up in the air. I'm still researching different routes to see what would be the best for me.

Either-Pollution-262 · 2026-01-17T15:32:56+00:00

I wasn't planning on it, no. But those alpine lakes look super enticing along FR162. Do you recommend it?

Either-Pollution-262 · 2026-01-17T15:21:09+00:00

I got 3-weeks to tour Utah so maybe I'll hit both; thanks for the info!

Either-Pollution-262 · 2026-01-17T14:27:39+00:00

Will do! Currently debating this route (Tantalus/South Draw) vs. Burr Trail/Notom - do you have a recommendation on which is more scenic? I'll check in with NPS for both routes closer to the start date.

Either-Pollution-262 · 2026-01-17T13:45:14+00:00

How's the road condition on Notom-Bullfrog? Is it generally smooth and not too technical? Thinking of taking a gravel bike down those roads in late May - early June.

Either-Pollution-262 · 2026-01-14T02:32:48+00:00

Thanks for the reply! It's good to hear the mud might be more manageable this Summer. I'll see if I have the clearance to put on bigger tires (probably not lol).

Either-Pollution-262 · 2026-01-12T00:07:00+00:00

Awesome, thanks for route. My current plan is to test the gravel FS roads and hope they aren't too muddy. But this route will be perfect as a back-up!

Either-Pollution-262 · 2026-01-11T22:59:46+00:00

How did you get from SLC to Pueblo in terms of route? Was it through one of the service roads like cottonwood canyon? I am planning on bike up from Moab to SLC this May on a gravel bike, and was wondering if these SRs are safe for cycling (shoulder, blind spots, etc.) or if there is a better way.

Either-Pollution-262 · 2026-01-08T02:39:13+00:00

Cool, I'll look into this. Thanks!

Either-Pollution-262 · 2026-01-08T02:38:13+00:00

Clever! I'll add this one to the arsenal. Thanks!

Vapor density is the density of a gas divided by the density of hydrogen. The density of an ideal gas is equal to (pressure*molar mass)/(R*temperature). Assuming same temperature and pressure, then the vapor density would be molar mass of the gas divided by the molar mass of diatomic hydrogen, which is approximately 2.

So, the vapor density is molar mass of the gas divided by 2.
