I ride exclusively tight twisty singletrack with lots of roots. Very quick steep climbs (like less than 20-30') with same descents and small drops. No desire to race or become a downhill rider. Just wanting to have fun. Which Trek bike best fits this style of riding? I am 6'4" with a 36" measured inseam so an XL or XXL is a must. Was considerint Tallboy but this may be overkill for the style of riding I do. Also, I may be riding the bike 2-3 miles on pavement to get to the trail heads. Lastly, old (49) and brittle (neck issues) so full suspension is a must!!!! Thanks!!!!
