Yeti’s first model for the world of bigger mountain bike wheels is called the Big Top 29er. They designed it to seamlessly to mend their instinctive Colorado bred handling traits that all Yeti fans live for with the benefits of better wheel flotation, momentum, and traction over their 26″ models. The end result is a highly versatile, go-all-day marathon style mountain bike that butters rough trails while keeping you strong and fresh for the last sprint back to the car at the trailhead.
The front triangle of the Big Top is designed using 7005 butted aluminum tubing to make for an ultra-precise handling bike with great power transmission when standing out of the saddle when climbing. 7005 aluminum is well known for its stiffness and being great for efficiency. But it can be a bit harsh as it transfers most trail washboards or rocky bumps directly to the rider. The bigger air volume from the 29″ wheels will help to quiet this vibration that is fatigue-inducing, but minimally it’s still there, slowly depleting the mountain biker.
The engineers have gone the full extra mile and combined a high-modulus carbon fiber rear end to their 7005 front triangle to dampen that aluminum harshness. What you end up with is a smooth ride that is very lively with some weight reduction. This will effectively make the Big Top a highly capable marathon mountain bike. Its carbon rear end also has Yeti’s iconic looped chain and seat stays which reflect the successful years of the famous Yeti FRO hardtail in past years. The frame hits the scales at a feathery 4lbs with the Yeti Chip system dropouts. Their dropout system allows for the standard quick releases, or to be converted to the newer 142 x 12mm thru axle wheels available.
The geometry is designed for a 100mm suspension fork. But they don’t limit you to that. You have two other options of a 120mm or a shorter 80mm travel fork, knowing however these change the geometry and handling. The short travel fork will make the headtube a steeper angle for quick handling while a longer fork will make the headtube with slower handling style. The Big Top frame is built with a tapered head tube for increased 29er steering precision.
The drivetrain options are numerous and fit the criteria of just about any mountain bike junky. One example is to utilize the removable ISCG mount and use an e-thirteen chain guide to run a bulletproof one by ten or one by eleven set up for miles of simpler, abuse friendly riding.
The Yeti Big Top comes in three different sizes from medium to X-Large and one great color for 2012—Black. It takes a direct mount front derailleur, a 30.9mm seat post and a standard 73mm BB. Yeti gives a fantastic five year warranty with the Big Top frame.
