been racing unattached for around 3 years now, and I'm getting close to upgrading to cat 2. It's probably time to join a team and seek some mentorship from those more experienced than me. luckily, the area I currently live in is filled with teams, and a lot of them show up to the weekly group rides. I'm trying to weigh the pros/cons, and things I should consider, and I'm wondering if others can pitch in.

pros:
mentorship
carpooling
working with teammates, and strategies
paid race entrance fees (maybe?)
discounts on parts (maybe)


cons:
time commitment
working for someone else on my own dime


priorities list:
experience on the team
serious about racing
potential to graduate to an elite team
sponsorship support

what am I missing? how should I approach the teams?
