Well my ride today was Hard but I did replace the Trek 7300 as the tow bike with what use to be an alu access rebuilt ;still has it's bottom bracket and frame the dog thought I was nuts comming back 4 times to repair stuff and put air in the tires ///between fixing and 20mile ride it took nearly 5 hours//I did repair a little roadmaster that after all the cussing and fumeing I think Ill give to some poor unsuspecting child to hate as much as I do/Kenneth
