Mountain Bikes

Custom Built Steel Frames

O’Leary mountain bikes are built for all day comfort and performance – in the dirt. Currently all frames are 100%  brazed, using a 44 millimeter headtube, and 73 millimeter standard English threaded bottom bracket. Drop-outs come in a variety of styles but typically we use thru-axle styles. The geometry of our mountain bikes are tuned to the rider’s preferences and use a range of 67-71.5 degree head angle and 72-74 degree seat-angle. O’Leary mountain bikes utilize decades of off road designs with attention to modern advancements in front suspension, disk brakes, dropper-seat posts, tire designs and drivetrains. Let us build your next ride with 100% True Temper steel tubes – while they still are producing tubes (thru the end of 2017 only!) –  and honor America’s only steel company still producing tubes for cycling with a made-in-America mountain bike!
