Diamondback Overdrive Sport 29er Mountain Bike. If you're a member of the declining population of riders who still hasn't thrown a leg over a 29er, the Diamondback Overdrive Sport might just be the bike to push you off the fence. There's just no denying the rock-crawling, root-crushing power of a larger 29 wheel. Making the largest of obstacles the smallest of matters is a defining trait of these rigs. Throw decreased rolling resistance, increased traction when cornering, as well as improved ground clearance into the conversation and this 29er is sure to sway even the staunchest skeptic. First off, this lightweight aluminum bike is a climber and an obstacle-conqueror par excellence. At its core is a 6061-T6 aluminum Overdrive series frame boasting newly formed top and down tubes, a machined head tube, and forged drop outs for added durability. The ever-so-sloping top tube provides ample stand-over clearance while geometry-wise the frame is perfectly on target for making quick work of cross country and trail-riding endeavors with a 71 head tube angle and a 73 seat tube angle. The 390mm (15.4 inch) chainstays, too, ensure this 29er is extremely responsive and a flat-out joy to ride. The Overdrive Sport's 29 wheels give you a leg up when it comes to rolling over rocks, roots, and such but you'll surely appreciate the SR Suntour XCT-LO 29 suspension fork up front that ably delivers 100mm of travel for the perfect amount of cushion. Changing gears is a piece of cake on the 24-speed drivetrain with trusty Shimano derailleurs front and rear coupled with Shimano trigger shifters on the bars. The SR Suntour XCR SIX crankset features a tried-and-true 44/32/22t chainring selection and coupled with a wide-range 11-32t cassette on the rear wheel you've got the tools to both ascend like a mountain goat and stoke your inner speed demon on rip roaring descents. And speaking of bombing downhill, the Shimano BR-M395 hydraulic disc brakes and their astounding stopping power will let you rein things in before they get outta control. Weinmann is a renowned purveyor of quality rims and their SL-7 Doublewall aluminum model here on the Overdrive Sport provides peace of mind and trusty, predictable handling over any terrain. While wolverines are not something we recommend tangling with in the wild, we'll make an exception when it comes to WTB Wolverine tires as their slight tread profile belies its fierce bite. This fast-rolling, 2.2 width tire tackles dicey descents, flies across flats and devours steep climbs all day long. With such a bevy of awesomeness exuding from the Diamondback Overdrive Sport we wager it's a lock that this rig will boost the fun factor up to Mach 10.
