A lot of my singlespeed friends are riding 29ers these days. The idea of wheels that roll over terrain more easily is quite attractive. But what about all that rotating weight? Won’t the bike still be slower and harder to pedal up these tough Colorado climbs? I set out to find out the answers myself with an informal little shootout. In this article I will comparison test two somewhat similar steel hardtail singlespeed bikes. I will outline the component spec on each, describe the course they were tested on, and detail my on trail impressions. Finally, I will give my personal thoughts and conclusions, followed by recommendations on which bike might be the best for you. Keep in mind this is a 26 vs. 29er article, tested in single speed configuration. Why single speeds? Why on earth would you want to climb mountains with only one gear? Lets not get into the why’s, pluses, and minuses of singlespeeding, that is another story entirely! This story is already way too long as it is, so let’s get started!
THE COMPARISON
I drove both bikes up to the Betasso Loop outside of Boulder. I rode each bike over a set loop and timed myself, meanwhile making notes in my head, comparing the bikes over the same terrain on the same day. I wanted to compare the bikes one right after another. It can be hard to compare bikes on different days, as my energies and motivations vary day to day. I did not wear a heart rate monitor. I did not have a power meter. I did not set the bikes up exactly the same way. If you want a totally scientific comparison, check out CyclingNews’ Tech Feature: 26 vs. 29 inch wheels. Unfortunately, that project has been in the works for well over 6 months with no final results published, so I decided to conduct my own. While the CyclingNews comparison is all about science and performance, I want mine to be all about fun and feel. With a little bit of numbers; because getting dropped is no fun at all!
The subjective nature of this test is of course the biggest limiter towards any sort of validity relating to my course times. I just tried my best to go the same speed on both runs. I did not go all out, rather, “comfortably hard”, which is around 80%. Well, except on the Canyon Link, because on a singlespeed that trail is an all out event, but more on that later. I have ten years of heart rate race training experience, as well as a season on a PowerTap under my belt. I’m pretty confident in my ability to monitor output and effort. Plus I’m a bit of a wimp these days; I don’t like to suffer too badly, so I’ll generally ride as fast as I can without really suffering too much. I’ve had enough of the pain cave. I like to smell the flowers a bit more these days. On to the 26 verses 29 inch wheel trail review.
THE BIKES

Bike #1: On-One Inbred 29er Single Speed. This bike to me is kind of like the British Surly: Economical, Image-conscious, bombproof, but not particularly light or high tech. The sliding horizontal dropouts are cool. This bike can be built as either a geared or a singlespeed without derailleur. There is pretty good tire clearance, and a lot of standover. Unfortunately the Rock Shox Lockout knob does hit the frame, thus the piece of rubber stuck on there. This is a common 29er problem. The seatstay tubes and yoke are a cool design, although not a particularly weight efficient one. The bike has Avid Juicy 7 hydraulic disc brakes, a Rock Shox Reba 80mm fork, and XT Hubs laced to WTB Trail 29er rims. Traction is controlled by Maxxis Ignitor 2.1 29er tires. The rest of the parts are reasonably light components. Gearing is a 32×20, which on a 29er is 47.2 gear inches.

Bike #2: Curtlo Single Speed. I bought this bike cheap and used at VeloSwap two years ago. I don’t even know the year or the model. This bike was hand made by a small builder in Washington State. It has True Temper Platinum OX steel tubing, butted and ovalized at the bottom bracket. The S bend seatstays have monster tire clearance, 2.5’s are no problem. I love this bike; it is very smooth and very stiff. It still steers pretty quickly even with the 120mm Fox Talas Fork I have on the front. It has Paul’s Components V-brakes, which are the best V-Brakes that I have ever used. The brakes grab ceramic rim surfaces on my 1st generation Bontrager Race Light wheelset with Chris King Hubs. Ceramic rims make a huge improvement for rim brakes. They are a whole level of performance increase over regular machined surfaces. The front tire is a WTB 2.5 Weirwolf and the rear tire is a WTB 2.4 Motoraptor. The rest of the parts are a small bit lighter than the On-One, but the spec is similar. Gear is a 34×19, which on a 26er is 47.4 gear inches, which is almost identical to the On-One gearing.
