The 29er advantages are as follows: Larger wheels roll over obstacles more easily due to decrease in approach angle.

 

The 29er bikes tend to offer taller riders a more natural frame geometry. The Speedone M8 29er is built of a Reynolds 853 seamless air-hardening steel tube set, the ultimate tensile strength of which is 1250~1400 MPa. Stiffness and strength are improved by heat treatment.

 

With a Reynolds 853 frame designed to optimize the trail-riding advantages of the larger 29-inch wheels and PF30 shell, the M8 29er flows through the rough stuff and devours the climbs.
