I have Reserve 40|44 and I liked them so much I bought a second set of Reserve 42|49 for a road wheel set. They’re in your price range with a lifetime warranty and tons of great features.
That being said, for $2k I don’t know that any wheel (even for $5k) is going to be a huge or even that noticeable of a performance gain vs your current wheel set. Might be nice to have a spare wheel set if you want to mount a backup set of tires for a course that might change conditions when you arrive or swap a wheel at aid stations if necessary.
Seems like a lot of people like the Envy wheels. I have been looking online and have yet to find a deal for them, but I just need the wheels before Big Sugar so I can wait.
How exactly do you actually purchase a chosen wheelset on NEXT website? I have gone to look at pricing and all the options and add no’s are so confusing and it dose not actually tell you the price. Or am I doing something wrong?
