I finally bit the bullet and moved from my road bike to a new tri bike. My innaugural ride was 45 miles through rolling hills. Prior to the ride, I pictured myself tearing through the streets of rural NJ like a Tour rider on time trial course. Not so fast . . . I probably road 25 of the 45 miles on the bullhorn bars because I lacked nerve (i) on descents (not hair-raising descents, mind you, but 28-35 MPH descents on rolling hills), (ii) where grooves in the road and other minor obstacles made me edgy, and (iii) where I had to really slow down going uphill. That said, I loved my bike -- a Trek Speed Concept -- and can't wait to get it out on the road again. Did it take others awhile to get used to the aero position (with no brakes in the aero position)?
