Whoa! Two posts in one day! It's a new record for me. We're unusually slow at work right now.
So, the obvious, near-universal, trend right now is for internal nipples to be used with carbon rims. Whether or not carbon rims should be used for 'cross and who should be using them are really conversations for another thread, and have been covered ad nauseum on other boards.
My question is simple: are there any carbon rims out there, except for the Corima cyclo-cross wheels, that have external nipples?
With so many new manufacturers of carbon rims coming out of the woodwork in the past two years, I'm surprised there hasn't been at least more than one set of rims sneak through. If I were to buy a pair of carbon rims for cyclo-cross, I'd want the nipples available for truing the wheels. I know, I know - most manufacturers swear that, if their wheels are built up properly, they shouldn't need truing; however, the thought of an out-of-true wheel needing a minor adjustment, which would turn into a four-day affair, what with re-gluing and all, makes my stomach churn and my good sense to send me back to the trusty Escapes or Reflexes. The other concern I've got, on a related point, is the possibility (theoretical or real, I don't know) of the dreaded pull-through, and a weak nipple connected to a stressed spoke resulting in a broken rim.
Ah, at the end of the day, the carbon rims probably should be reserved for riders much faster than I am who get exceptional deals through sponsorships, or, kept available for those select few who race and are wealthy enough to not have to work for a living; but, I still have dreams of the handbuilt Edge Composites 2.38s (with external nipples), Sapim Lasers, and White Industries M15s with the Phil Wood submersible bearings.
