Looking for some advice. I have a broken Mavic Carbon 52mm rim - photo attached. The hub is still good so was thinking of buying a Chinese rim and getting it rebuilt with my existing hub. Can anyone recommend a good quality open mold brand for 50mm rims which ideally looks similar to my Mavic?

(Apologies for the size of those photo's - don't now how to resize them)

What the heck happened to that Mavic rim? It looks like a spoke pulled out, like would if something got caught in the spokes, but then that dent almost looks like it melted or something, despite it not being near the brake track. This isn't a "bike rack put the wheel too close to the tailpipe" situation, is it? :wink:

I actually don't know - I'm the 3rd owner & the previous guy didn't seem to know either. He threw in this wheel for free. A wheelbuilder told me the aluminium rim is busted inside.

We purchased a Light Bicycle rim and it matches really well.
thanks for the advice - will enquire with LB. Have also reached out to FarSports.

Nextie just updated their website, so I was having a look around, and came across some new 32mm wide rims. With a 22C inner diameter, these would work really well with 28mm tyres. https://www.nextie.com/new-gravel-clincher-NXT35GR

As mentioned, I was able to run a little less pressure in the 25's, so they were a bit more comfortable. I'm 83kg, so I run more pressure in the 23's to prevent pinch flats, still comfortable, but not what I would call a cushy ride.
What pressure did you run on 25's?
I want to say I ran those at about 85/95. I have 28's now that I'm running at 80/90. Could probably go a lil lower, but I'm afraid of pinch flats, they're still pretty comfortable and handle great.

With 30% more air volume than a 25mm tyre you would struggle to pinch flat a 28 tyre at 60psi. I’ve accidentally run mine as low as 45psi and been fine.

Last Sunday i managed to double pinch flat front 25c and rear 28c Continental GP5000 on 23mm internal width rim. Both are pumped at 65psi. Rider weight: 67kg.
It was a legit hit with loud impact noise into a deep hole that i didn't see because it was covered by grass.

Apart from that, i didn't get any pinch flat from this kind of pressure before.
