Welcome! Is 26 and 2.1 your wheel and tire sizes? If you're really new to MTBing, you could also try Huber woods. It's a little easier than Harts and a good place to learn.
thanks TimBay. not new to MTB but took a big time off from when I live in Utah till I move d to Moco. Was an XC rider - Long flowy trails..no rock roots. etc. Loving hartshorne. (cuesta, laurel and Grand tour) need to get over to Huber. Ive got a new bike on my todo list. def. can justify 29 dropper and some more suspension for these trails. my 2008 Giant X2 trace doesnt owe me a penny
