650b x 28mm tire / rim problems

[bicycletricycle]

I have a friend, she has a super small canyon road bike that came with 650b wheels, she runs 28mm tubeless tires on them.

She has had some flat tires and could not get the tire of to repair them.

She is running tubes now.

I want to help her.

Option 1. Get her on some better tires and sealant that will reduce the chances of her getting a flat in the future. She has some mavic wheels on the bike and I have no idea what the best 650b x 28mm tire would be for her. I think she has some kind of maxis things on their now.

Option 2. She is comfortable with taking tires on and off and changing tubes so maybe just building her some non tubeless 650b wheels with rims that are easy to get tires on and off of.

I prefer 2 because I do not like tubeless but the only rim I can think off is a Dyad which a little heavy for her and she also has a disc bike.

Can anyone think of a nice 650b disc rim that is easy to get tubes tires on and off of?

or

What is the best all around reliable 650b x 28mm tubeless tire?

Schwalbe makes the pro-one tubeless in a 650b / 28mm spec. I think that is by far her best bet on tires.

Can't really help on the rim - standards being what they are, it depends on the tire and the rim.

I've never had issue getting tires on and off my Stan's Crest Mk3 650b rims. They are on Mk4, but I would expect them to be just as easy. Too wide for a 28mm tire, but I'd be comfortable with 32s, personally.

Why insistent on 28mm tires? If the frame will fit 32s the extra volume and lower psi will be beneficial.

Pacenti Forza or Kinlin TL23 would be fine options if she wants to stick with 28-584.

32mm tires include Conti GP 5000, Conti Contact Speed, Schwalbe Pro One, and many others.

28-584 still available from Conti, Schwalbe, and maybe others.

frame barely fits 30s, fork barely firs 28s

If you want to stick with Velocity, why not Ailerons? I used them for a while on a tandem and they were great, and I think the perfect inner width at 21mm. I only switched because I needed something beefier for a tandem.

[bicycletricycle]

Because I know dyads are extremely easy to get non tubeless tires on and off of.

I have no idea if the ailerons will be any better than the mavics she has know, both are tubeless so both with will be tighter than the dyads.

Another vote for Velocity Ailerons..GREAT rims.

How are they with tubes? Easy to get tires on and off? I know this is subjective

FWIW, I have two Quill (edit: not Aileron, sorry, but same basic rim) wheelsets, one 700c and one 650b. Neither have presented any issues mounting or removing Rene Herse/Compass, Grand Bois, Ultradynamico and Panaracer tires. I'd say comparable to a HED+.

Love this. A classic example of YMMV.

I spent more than an hour mounting a pair of Pacenti/Panaracer 42 mm Pari-Motos on 650B Belgium + rims earlier this year. My worst tire mounting experience ever… blisters, sweat, bad words…

Hoping they’ve stretched a bit if I ever flat. Thankfully they’ve proven to be great tires and so far no flats.

Anyways, my experience with 650B rims and mounting tires is pretty limited but mounting Rene Herse and WTB tires on WTB rims was much easier.

I feel like tubeless for non-technical folks does not make a whole lot of sense. When you need to change a tube, most people can solve that. When tubeless fails, it's a process to troubleshoot. Especially for small people on the road, I don't see the advantage unless you live in goathead territory.

Gotta agree..another 'technology' that started life in the MTB world..Low pressure but less or no pinch flats as you bounce over rocks and roots..Not a lot of that in the road world..'Maybe' some in GRoad bikes.....

I'm helping my sister get a new custom bike built. It's designed around 650Bx38, like my Bingham. A discussion I want to have with the vendor is about tubeless and hydro discs, because of the maintenance, and because, like many riders, the bike will likely hang on a hook for the colder months. So I'm suggesting tubes, even though my bike is tubeless, which is a better choice for me as a year round rider.

I'd like to also do the Growtacs instead of hydros. Thinking of a 12 speed Shimano Di2 drivetrain...

Even as a technical person, some of my tubeless bikes get ridden infrequently enough that it's a tossup whether tubelessness is a benefit to me. I wind up with a solid blob of sealant from the bike hanging for a month at a time.

This makes sense to me. I have a Big Dummy and a Raleigh 20 folder, both of which have tubes, because they are ridden infrequently. The two all road bikes (650B, 38 or 42) and the MTB are run tubeless and for those bikes it's totally worth it. Below 38mm I run tubes so far, no bikes with pressures over 40 psi have tubeless set-ups.
