To expand Bill's point: the engine matters more than the wheels. Several thoughts:
-- once up to speed there little cost to heavier rims, so unless your friends stop and start a lot, there will be little actual benefit other than lightening your wallet and increasing your acceleration. -- have you done aerobic training? Maffatone's Big Book of Endurance gives a lot of info on the concept, but the simple version is ride aerobically (as opposed to anaerobically) only for three months, ideally breathing only through your nose (this takes some learning). Aerobically = 180 beats per minute minus your age, but the "decline with increased age isn't linear, so if your 50 you might really be more like 135-140. This gives you an aerobic base that is fat burning rather than sugar burning, and far more efficient, so you go farther faster with less effort.
