General Bike Geometry Help.

When looking for a road bike that is a little more relaxed and upright riding what would you look for before riding?
I know I will need to ride them but hoping to narrow it down a bit first.
Thanks

It depends. If you're looking at nice, brand name bikes they'll often be described as "race" or "comfort." Comfort bikes will be more upright. If you want the ultimate mix of "upright" and "road bike" you'll want to look at hybrids. They're essentially comfortable road bikes.

"Endurance" bikes are built to be comfortable. "Race" and "aero" bikes not so much.
Look at this page on felt bikes to see a visual comparison of different types of bikes.
Road - Felt Bicycles

If you want something even MORE comfortable, consider going for a "lifestyle" bike or even a cruiser. Felt's "adventure" bike series also looks "upright" and comfortable.

I'd imagine that the other name brands have similar bike designations.

Basically stay away from "race" and "aero" geometries.

ISTM that comes close to the definition of a touring bike. Touring bikes also have fatter tires than flat-out road bikes, if you don't mind your teeth not rattling while you ride.

I am looking for that type of bike (Touring) I do run wider tires.

My lbs has a Ritchey Cross frame they could build up for me, could this be built into a touring style bike? I am looking for something that can support a heavy rider.

You really want rack and fender eyelets which that's lacking.

Racks with panniers make commuting with laptop/work clothes/cold weather cycling clothes/rain gear much more pleasant. Fenders will keep rain spray out of your shoes and chamois.

Randonneuring frames are another option - they're setup to cover long distances at reasonable speed which implies clearance for larger shock-absorbing tires and less aggressive positions.

It does sound like a touring bike will fit the bill nicely. oh and speaking of 'the bill' ...saying how much you can spend will do much to narrow your search

Hoping to be around $2500 or less with a good group set.

The basic difference is distance between wheel axles. Like a stretched out limo. Touring bikes should have a rear wheel that's spaced around 2-1/2" from seat tube. Rear dropouts should have eyelets for attaching a rack. Extra spacing keeps your heels from banging into panniers. Front wheel will also have greater frame clearance. Some of the best touring bikes were made pre-1990's before lawyers began straightening forks & raising pedal clearances.

I agree with most of your post, but I didn't know that forks became straight because of legal concerns.

Soooo ... what's wrong with the touring bike you already have -- Specialized AWOL?

It says you already have a Specialized AWOL. That would mean you would rent, depending on your location, a road bike that's radically different than that AWOL. Otherwise, I think you would end up narrowing down to something just like the AWOL.

I love my AWOL, looking for something a little lighter for longer rides. When I lost 100# I rewarded myself with a Trek Emonde S with some custom built wheels. I either need to upgrade the group set or trade it for something a little more relaxed. At 300# I am not sure if I should be on carbon or not.

Apologies if I sound obtuse, but I'm still not getting it. If indeed you have an Emonda (I don't know what a "Trek Emonde S" is), well ... there: you have a "lighter [bike] for longer rides". That is what an Emonda is for.

You also have an AWOL, a bike that you say you like, that is not all that heavy to begin with, that is steel, that has a more relaxed 'touring' geometry, that can easily swallow wide(r) tires, and that you could easily 'upgrade' if you thought it necessary in order to shed a little more weight from it and/or just make it that bit nicer to ride -- if that matters. If indeed you do weigh 300lbs or so -- and no, this is not snark -- then I would have thought the AWOL is the perfect sort of bike to be going on with for now.

The Emonde is more of a race bike and not as comfortable as my AWOL. Looking for something in between the two.

So, not a touring bike then, but something more like a Giant Defy, Specialized Roubaix, etc. etc.: so-called 'endurance geometry' roadbikes. 'Endurance' is just a euphemism used by bike manufacturers (they all make 'em) to refer to road bikes with relaxed geometry: higher stack/shorter reach/more upright position; aka 'old guy' (like me) road bikes. Or, as @Drew Eckhardt noted early on in this thread, if you are worried about carbon you could investigate traditional -- usually steel -- randonneuring frames.

Exactly, I guess I should have used relaxed geometry rather than touring. I also like having 2 bikes in case one has to go in the shop I do not miss out on riding.

As you go up in price Cyclocross bikes are more for Competition and so a bit steeper
for all the standing up on the pedals you do to regain speed after tight corners, Etc

seat tubes 73 degree is common, relaxed is less Head tube angles Touring 71 is nice & relaxed..

but Trail is actually your steering geometry number .. combining Head tube angle and wheel size And fork offset .

Yes, look at the geometry charts for a major brand, such as Trek. For the Comfort Road type or Endurance, you should find the head tube 1 to several cm longer than for one of the Race or Performance models, size for size. The chain stays may or may not be different but th trend is right. Tire clearance is hard for the bike companies to quantify, but if you look at the tires it comes with new, you might get some insight.
