I’ve just made the decision not to go back to a 26er having spent 2 months riding my budget 29er. It’s been a tough decision to sell my SC BlurLT in favour of a £125 hardtail frame but the 29er just feels right, more stable on technical stuff, better rolling on the open trails and so much more fun in the singletrack plus much more traction when climbing plus it just rolls over stuff. The decision was cemented last week when i rode the Blur again on some singletrack and couldn’t string 2 corners together and just couldn’t settle on it.
My advise, get a cheap hardtail 29er and try it against your current 26er and see what you think, i found it a revelation. 😛
FWIW i got a Viper 29er from CRC for approx £125 and for the price i don’t think you can really go wrong with it, picked up a set of minutes for £250 from CRC as i couldn’t face going back to rigid forks and a 2nd hand set of wheels although i believe that the on-one retards are good value for money, i love the build and can’t wait to get to 24/12 later this month to thrash it round Newnham Park 😉
