One of the key components to what makes Airborne Bicycles a good value are the parts that are selected for the complete bike build. The highlights are the RockShox Reba RL fork with lockout, the RockShox Monarch RL shock with lockout, SRAM X7 2×10 drivetrain, ELIXIR 3 hydraulic brakes and the WTB SpeedDisc I-19 rims. To help cut costs, Airborne uses their own house brand handlebar, stem and seatpost. All of the house brand components worked fine and we had no problems with any of them, other than wishing for a wider handlebar (the stock bar is 25″ wide). Some might want to add a dropper post, however this will add weight to an already not light bike. The quick release seatpost collar worked fine for our uses. Also to keep prices low, the hubs on the standard HobGoblin are generic, but functioned fine during our testing. The one part that we would definitely change would be the tires. The Geax AKA 2.2″ 29er tires hold back the HobGoblin on the downhills and corners. Fortunately upgrading your tires is cheap and easy. The SRAM X7 drivetrain worked adequately, as did the Avid Elixir 3 brakes. The only thing we noted was the black aluminum brake levers had a decidedly plasticky feel compared to what we are use to.
Here is a complete product spec list:
Although listed as a 15″ on their website, the HobGoblin we rode was marked as a 15.5″ model and fit more like a 15.5″. All frame sizes have a 74 degree seat tube angle (with sagged fork) and a 71 degree head tube angle (with sagged fork) according to Airborne. The wheelbase is 44 inches and the bottom bracket height is 13.3 inches according to our own real world measurements. The chainstays are a bit on the long side, they measured 17.8″. The overall geometry and feel of the bike is more slack than a lot of XC-oriented bikes out there and this applies even more so for me. At 5’5″ on a small 29er, my fitment on the bike means my riding position adds to the slacker geometry. There was no toe overlap on this 29er.
Here are the geometry measurements from Airborne:
