I'm the king of buying gear that doesn't provide material gains.
The bike frame is one of the lowest on the Benefits/Cost ratio scale. Down there with ceramic bearings almost.
That being said, if it makes you feel good, makes you feel fast, and keeps you engaged and interested in the sport, that's worth a helluva lot.
The brain is an important component to the training and performance mix. It's often overlooked.
I just bought a new Felt TK FRD. I'm pretty much hoping that it scares people into submission on the track and I don't even ever have to get out of the saddle...that's the plan, anyway
