Road Wheels & Road Wheel Recommendations?

with an internal width of 22mm, is it likely for the tire to balloon any bigger than with the 21mm internal width wheel?

Yes

I wouldn't have thought an extra 1mm of internal width would've made that much difference. Do you think it would be enough to overcome the 2/3mm clearance either side of the tire?

It will reduce it even further below the 4mm which is considered safe, but not to zero.

What's the go to budget OTP wide clincher rim brake wheelset?

Cheap winter / commuter wheels, 17 or 19mm internal, rim brake, shallow, campag hub. What to get?

Like he said ^

Askiums

I got some Prime wheels for £180 last year that were 1500gr, 19mm internal and uses normal J-bend double butted spokes... With tires and tubes!

Yeah I think I found those on a list somewhere. Sold out, and no campag freehub option.

I don’t do Mavic

Shimano RS 100 is what I would get for costumers. Not necessarily better than Mavic, but normal everything, easy to service

I don’t do Mavic

But you do do Campag, so you're narrowing your choices. The base model Fulrum wheels are no better or worse than Aksiums

Whatever campag wheels fit your budget. You honestly can't go wrong with campag wheels.

Really I should just upgrade the winter bike to 11sp then I can have my choice of hoops.

Been happy with bomb proof Fulcrum 7 LG for years so I'll probably just get 'em again, was just hoping to get to 19mm ID as a bonus upgrade.

Dangerous to get into a debate with you, but the problem with some Mavics is the fact they use a bushing not a bearing in the freehub. I have personally had two sets (and know of at lease two other people) that have developed the Mavic scream of death. It's pretty scary when the freehub decides to lock up at speed and the chain backs up.

No danger here, I'm aware of the problem with FTS freehubs and have pointed it out on here before. Everything is a compromise; for some users the FTS problem is too much, but for many more it's a price worth paying for the desirable attributes of some Mavic wheels.

In defence of (some) Mavic wheels; I have a pair of Kysrium SL, they have the aerodynamics of a housebrick and are not featherweight. But, they have a great redeeming quality, they refuse to die. They remain my holiday wheel of choice where spares don't exist. They have survived the worst roads of four Continents and Sussex, I can't remember ever truing them.

Are you 10sp?

You can run 10sp cassettes on an 11sp hub with a spacer.

{edit ... not nicely with Campag}

Buying endless non-rebuildable factory wheels for a rim-brake winter-bike is an eco crime.
Change my mind.

Can be recycled like beer cans.

When they last 5+ years and I’ve never owned a car as a result I think I’ll sleep ok.

Problem for the average user being servicing it will come at more expense than buying another OTP

It needn't be (and isn't) that way if you think ahead.

Just switch out the rims, re-use spokes. Bearings or even freehub refresh if needed and carry on.

I've recycled rims and cassettes.

You'd have to take hubs apart? ... and cycle to the tip and get a bunch of punctures ;-)

That's all fine and dandy for bike geeks with nothing better to do, but normal people don't have the tools, time or skill to do that for themselves, and they're not about to acquire them just to virtue signal about speculative ecological benefits.

On Mavics: I have a set of ksyrium allroad pro disc

1. Nipples have seized on spokes, which are generally not stocked and are pretty expensive to get. I’ve broken a few cycling
   
2. Hubs have some sort or proprietary system which my excellent local mechanics apparently don’t know what to do with
   
   

This doesn’t strike me as ideal.
