My Planet X Model B rear is probably on the way out at 9,250 miles, so I've ordered a replacement wheelset. I'm just wondering with Planet X is there wear indicator that starts to appear when the rim is worn ?
Planet X wheels wear indicators?

I find wear indicators on wheel rims generally start to disappear when the rim is worn. The wear indicators on my DT Swiss TK540 touring rims are small indents, spaced well apart on both sides of the rims, 14 per side. These don't affect braking at all.
By the way, I once bought wheel rims with wear indicators that were grooves running along the midldle of the rim, and found out that the brake pads tend to wear either side of this groove, to the point where every time I applied the brakes, the pads would stick to the rim. So I don't recommend buying rims with this kind of wear indicator.

Thanks, I've had two types, the type where a marker is there from day dot and fades when the rim is worn, and the type where originally there's no wear indicator but as the rim wears it exposes a groove. I'm hoping the Planet X wheels are the latter type; I can't find any literature on the subject wrt P'X Model B's, however :-/

I'm asking about the old Model B's. There's no wear indicator on them from start but I'm hoping they are the type where a groove gradually appears (its not appeared yet), if thats the case I'll get a few more weeks out of them rather than exposing the new wheels (2014 Fulcrum 7s fwiw) to worst of winter.

How would that work?

PS, my previous quasar wheels (a Dutch make) were the type where the groove gradually appeared. The idea I believe is that it maximises the breaking area until the groove is exposed rather than the inverse when a groove is there from day dot.

It's quite simple the groove is gradually exposed when the rim is worn, maximising the braking area in the meantime.

I don't think there are new model B's? I get the impression the model B's are the old AL57's (then new AL57's are shimano 11 speed)

What other rims have a groove that appears in that way?

You are right, they are 2011 Model B's, I'll try googling around AL57s.

My old stock Quasar wheels (a Dutch brand) were like that.

So presumably the groove was machined from the other side of the braking surface - meaning that when it appears, the rim instantly fails in a catastrophic manner? Like it...

lol, it was pretty gradual on my old quasar rims, in fact they never failed they are still on the turbo bike. I'm not sure how they'll do it, perhaps they manufacture the same as visible wear indicators but just surface over it :-)
