I too saved for a long time and bought a dual suss 29er. It's ridiculous the crap I can plow through on that thing. I had been on a HT SS 26er for about 8 or 10 years. I think I did it initially because I'm cheap, and I was riding 5-7 days a week and wearing parts out a few time a year. I don't know if I'm afraid to break the new bike or I just missed the singlespeed but a few days ago I picked up a monocog 29er. In all the years of only having a SS MTB I never had trouble keeping up on group rides.
