Will 650b Bikes Re-emerge in 2012? “Signs point to yes”
When 650b marched into the spotlight, 29ers were facing resistance from mainstream bike-makers and a mid-sized wheel format seemed to be a reasonable compromise that offered the benefits of the 29er’s larger wheels while retaining the familiar handling qualities and component spec of a comparable 26er. The Momma-Bear wheel solution captured the imagination of riders, the press, and a number of tire and wheel makers, but the cycling industry was already having a tough time translating the benefits of 29ers. Explaining the benefits of 650b was more difficult because the mid-sized format appeared similar to its smaller 26-inch brother. With its clearly different profile and widespread support, the winds of change filled the sails of the 29er and 650b disappeared from the lineups of all but a few of bike brands. The re-emergence of 650b is already gathering speed, however, and insiders report that suspension makers are gearing up to produce 650b forks on the order of the biggest names in the bike biz. This indicates that 650b bikes are slated for future production.
Why? It’s no secret that Specialized and Trek are locked in a heated battle to own the 29er business worldwide. Both brands have sharp design teams who are struggling to adapt the 29er to the longer travel AM/trail market which is the fastest-growing segment. After 120 millimeters of rear-wheel travel, squeezing additional suspension from a 29er becomes a bit of designer’s nightmare as standard components crowd each other for space. On top of that, reinforcing the frame to counter the additional forces generated by big wheels and more aggressive riders heaps on weight – an issue that 29ers already suffer from. Those who have continued to develop 650b know that the harder those designers try to cram 29er wheels into a 160 to 180 millimeter chassis, the better 650b will begin to look. Plus, riders who are feeling pressured to jump over to big wheels might choose a mid-sized format if it makes sense, simply because it isn’t a 29er. The reasons for 650b may still be the same, but the circumstances are far more compelling. – RC
