take this w a grain of salt as this is the interwebs.
- road bikes are sized more specifically to you than a mtn bike, so if you get a road, get sized first or youll hate riding and most likely wont do it = waste of budget
- road slicks and 60psi = fast. o yea dont forget a decent standing tire pump for home, in addition to your 'on the road' pump. (on a mtn bike riding on street w knobbies is for noobies)
- if you dont already know, test out a few styles (mtn road crossover) to see what riding position feels best for you.
- long hours on the bike means sore butt, invest in a good seat.
- whatever bike you end up with...i would focus on buying the best FRAME/Fork combo i could get and w the idea you can upgrade the components later.....
many years ago i was in a similar situation w a similar budget.
i ended up getting a mtn bike so i could have 2 sets of wheels. 1 w road slicks. 1 w offroad tires. so easy to change up and less $$ and space than 2 bikes.
the mtn bike came w those starter front shocks but was better than not having any for my wrists/forearms, while i got used to being on a bike 18+ miles / 6 days a week.
searched the local bike shops with the idea i wanted:
- to support local business.
- to have them do the maintenance for 1 year. shops usually offer 6mon or 1 year w purchase.
i happened to be shopping when the new models were coming in.
bought a year old model and saved even more$ as the upgrades on the new bikes were things i was planning to upgrade on the one i got but w better parts than what was on the newer model.
good luck and knowledge to you on your decision.
