After having many MTB with full sus, 26 and 29 wheels, last year I went for my final
MTB build. On One summer season which is a steel double butted frame but not stickered as such so inexpensive, 26" mavic rims, hope hubs, brakes hope mono mini's 140mm rear 180mm front (nos as now discontinued) epicon 160mm front forks, sram gearing, xtr chainset, hope BB.
Its a ride all day bike and I love using it. Steel hard tail recommended
