ok here i go....
i need all the help and suggestions i can get on putting together a road bike for myself.....now i say about 90% of people who ride a road bike are not very tall and are usually under 200lbs.....now i weigh about 300lbs and im 6'2" ......as far as components i know what to get ...my problem is the frame, fork and wheel set???? what do u suggest?????
It's great you found this forum and are looking here, I wish I'd known about when I was looking for my bike, a lot of good advice....
You're big, but are you in great shape already? Or are you going to lose weight, etc.?
If so, I would concentrate more on a great frame, a bit less on the drivetrain maybe, definitely less on any real light weight exotic components which you'll put strain on right now and probably upgrade in a year or so when you're in better shape, know how you ride, are more informed, know what you like.
So maybe a pretty standard bar/stem setup like Deda, TTT, ITM, Ritchey base sets; Thomson Elite or Ritchey post; whatever saddle fits (even a narrow one might work, this one is totally subjective); maybe even the mid-range component group if you're gonna grind on it for awhile.
On the wheels, I too think Dave Thomas SpeedDream are amazing and a good price for what you get, but if you're going to lose significant weight and develop technique, then start out now with a bombproof OpenPro, 32 hole, 14 gauge setup and upgrade that later...no use in straining a $500.00+ wheelset now at 300#, and you'll really appreciate the change later when you're at peak shape and ready to use the tools.
If you're already in super shape, then go after all you can get, and call Dave on the wheels.
