Familiarity: I've used it several times

1st pair of GP4000s. I've used them for roughly 1k miles now, from mountain climbs and descents to spirited suburban riding on relatively good pavement. These tires roll fast, are light for a training tire, and have held up against most road debris. The front tire punctured at 859 miles, and the rear tire punctured at 936 miles - both due to the infamous goathead thorns. In both cases, the thorns punctured well off the centerline of the tire - possibly bypassing the Vectran Breaker layer? No experience riding in significant wet conditions.

Note: not sure if it is just my experience, but these tires can be an absolute PITA to mount on my Mercury M1 disc alloy rims. Maybe I just need more practice...

There's really not much to talk about with these inner tubes, which is a good thing. They're cheap and effective so far. No punctures caused by road debris or other riding-related events through 150 miles. Also, no significant air loss over time as far as I can tell.

The option of variable stem length doesn't directly impact me but I can see how that'd be a nice consideration for people running deep sectioned wheels.

I've never had real problems with any of the water bottle cages I've used. This cage continues that trend. I use it on a cyclocross frame with Camelbak Podiums and have had no issues with bottle security. Haven't tested it in an offroad application yet but for smooth road riding, it gets the job done. As a top loader I'd imagine it might have some access issues on a frame with a small front triangle (say, a full suspension MTB), but I can't see any problems with it on road frames.
