Hybrid, Limestone Trail, Tires
This subject came up a few times. I spend some money for new wheels and like to share my experience.
My Treck Hybrid 7700 is very good for these Limestone Trails. They are bumpy in places from tractors crossing and various critters digging holes. I like to go fast and therefore will hit these holes at full speed.
I have biked on these trails for many years using 80 PSI 700 x 38 tires. Works great but takes a lot of effort to do 50 miles in 3 hours. Well, it is mid summer and the trail is hard and dry. So I go and buy two new wheels with 120 PSI 700 x 28 tires.
The Hybrid shocks soften the 120 PSI hard tire action. The 120 PSI and 28 mm are noticeably more efficient so that the 50 miles in 3 hours become much more doable.
I should also mention that a Hybrid bike has better sealed bearings than a road-bike.
