I've got a lovely set of Enve 65's that I've been running for nearly 3.5 years now, and they've probably done at least 20,000 miles at a guess with quite a lot of mountains/hilly stuff and winter riding.

They've got a brake track indicator strip which is a small notch that runs all the way around the track, and the front has got to the point where you can just about see where the indicator used to be but you can't feel it any more. The track is mainly still nice and smooth but there are a few small pitted areas starting to appear.

My question is, when do I replace them, and are they going to explode next time I'm riding down a hill? Given their cost I'd quite like to run them as long as I can before replacing!

Have you put a straight edge against the brake track?

Might be the light and reflection but it looks concave to me.

Are they tubs or clincher?

If the latter take the wheel off and use a caliper to measure wall thickness?

20k miles is pretty good going mind!

Yeah they feel slightly concave too - I guess the question is how much is too much?

I was going to add, try and search for a wear guideline?

Minimal wall thickness, that kind of thing?

Found this:

Enve Composites
“Essentially brake-track wear on a carbon rim is not dissimilar from an alloy rim. It is important to keep your brake pads free of abrasive debris, which will ensure a very long wear life on ENVE’s carbon brake tracks. A brake track would be considered worn out if you can feel obvious cupping or deep grooves in the brake track. I’ve seen a few CX racers wear out brake tracks where dirt, mud, and sand are constantly present in the braking scenario. Another indicator is if you can see through several layers or plies of carbon over long sections of the rim. Finally, if upon inspection of your brake track you feel any other forms of deformation: waves, bulges, chips, etc. These abnormalities should be inspected by a local bike shop and/or manufacturer customer service should be contacted. For ENVE, we expect the majority of our customers to get 5 years or more out of their rim’s brake track. If the brake track is worn out due to extreme use, say in CX, we offer our Lifetime Crash Replacement.” –Jake Pantone, director of marketing

I'd say yours are done.

I expect 5 years means a MAMIL 5 years rather than the absolute battering I've given the poor things! Buy em to ride em comes home to roost!

He's not said anything other than sage advice though.

Concave track, wear through the layup etc.

Looks like you'll get 50% off on your next set.

Their support seem very chatty - I need to check whether there's any pulsing or vibration under braking then they'll advise me further.

Also worth looking at getting them rebuilt with new rims if the hubs are still in good condition.

Enve have got back to me - they should be good to ride on until I start feeling roughness or pulsing under braking, but they are getting pretty worn so they expect that won't be too long in the future.

So I've got time to plan what rims to replace them with thankfully tongue out Given how much I've loved these wheels it will probably be another set from Enve I suspect! They've taken an absolute battering (winter riding, mountains, racing, crashes) without missing a beat while I've got friends with deep sections from other (premium) manufacturers that have delaminated, split etc.
