In my continuing quest for the perfect urban commuting bike I a tested a Buzz at REI last night. Great price currently about $500 with member discount. Aluminum frame, alloy fork. Hayes Disc brakes. 26 x 1.75 tires. Shimano M475 hubs and SRAM X7 drivetrain, 27 lb. It was (to quote an old friend) something completely different. It was like stradeling a Lipizzaner stalion. the thing just about hopped out from under me. Serious FUN. Curbs, poholes, gravel, mud, rocks, grassy knoll- all no problem. It rolled remarkably well on the pavement too. I did not get to come down a hill at speed. The sprightly handling seems to come from a very short wheelbase (104 cm). It also had a very short top tube and a long stem. I suspect that the 'trail' is short as well. These are characteristics that are associated with low speed maneuverability but according to many web gurus also cause 'high speed instability". Is this something I need to be worried about if I ride at <30 mph? Will I crash or spin out? Anyone have opinions or experience with a 'twitchy' bike?
Thanks in advance: JimF
