Flow, hang on to those bikes longer mate. On Friday I had the opportunity to ride twoniners and my 09 Scalpel Carbon1 back to back (well almost). Although the niners were really good bikes hen I hopped onto my Scalpel the feel wasn't that different. Now that's a testimony to the leaps 29geometry has taken over the last 9years. Neither felt like a bus but neither gave my same cosy feeling of sitting in the bike either. Compared to the 26er both felt high and at certain points on Vasbyt, I cold feel that slight hesitation to want to turn in compared to the 26er. Been 12 years since I rode a fully rigid 650b hardtail so I can't compare any of the new 650's to the latest (If anyshop has a Scott Spark 700 series or latest Giant Anthem I'd love to compare the 29er to the 650b back to back. why I find it hard to part ith my 26er is because I'm more Schurter like in build than Absalon, so I tend to not like lots of short steep climbs on a trail. The lighter 26er wheels just feel more comfortable to get going over and after the obstacles. Well tuned suspension also makes the descents just as much fun on either wheel size. I also didn;t feel this Roll Over superiority thats often refered to, probabl because my 26er is a medium and therefore has a longer front centre than most bikes a LBS would recommend for me. The longer front centre give me a coupl of advantages: I'm further behind the contact patch so I'm more stable going over things the wheelbase in longer making the bike more stable overall. If I compare some of the number of the medium size rocky mountain element to my scalpel they stack up similarly except my Scalpel is slightly longer in the top tube. So the reason the bikes felt similar has bugger all to do with wheel size but everything to do with where my weight is placed between the wheels. IMO< ride the bike you like but make sure it fits you. a 29er faster in a stage race? LOL really,tell that to the multitude of 26er riders who finished ahead of 29ers at the ACE, and the 650 riders who featured prominently at the front of the race over the last 4 days. Anyone who buys into this crap should take a course on drivetrains, and gearing. A very good reason to buy a 29er is that every shop is pushing it so hard right now. I was watching some videos's on the debate on wheelsize between manufacturers at Eurobike and many are convinced that 650b is the way the direction the industry will settle. No one is convinced that 29er will last more than another 5 years simply because of the number of extra parts for all these wheel sizes that needs to be catered for. Wheel manufacturers want 29er and wide 700c for road because it will reduce the number of dies and moulds they require (A huge factor in the high cost of components today). Frame manufacturers want 650b because they can use parts from their enduro bikes on XC bikes meaning fewer tools and lowing production costs. only thing that they all agree on is that 26 is dead
