Hello to everyone. I've been reading into bikes for several months now and to be honest I feel like I'm going in circles. One site says one thing, the next provides exceptions, then I hear none of it's true, then I hear ALL of it's true, then I hear only some parts are true, and then I hear I've been looking in the wrong place the entire time and apparently I'm expected to know all these shorthand phrases and technical terms when I'm just starting out... To be honest I'm quite frustrated by the whole experience.
There are probably simple answers to my questions (see below), and while I don't feel as though I haven't looked hard enough, I'm beginning to wonder if it's true that I haven't looked in the right places -- and so I come to you!
So here are my questions:
1. What EXACTLY is a fitting (versus test drive) and can I skip it/do it myself in a shop?
The fitting itself (whatever it is) seems to be unanimously advised from all I've read, if I can find the right place to do it... but to me it seems like a general run of test-riding, minute tweaks that could be done by yourself, and repairs (?), and all of this done by someone there in the shop. But then I hear that plenty of fittings aren't very comprehensive at all and before you know it you've paid loads of money for something you could have done simply by straddling a few bikes in-store anyway. So while it is advised, what exactly is it, what are some tips to ensure that it's done properly, and can I do it myself to save some cost? The closest bike shop to me is an hour drive away and may not be all that quality anyway, so I'm reluctant to drive in and dive in head-first.
2. Is it the right bike -- or the right parts?
I'm 5'2.5 but 190lbs (yikes) and biking in a teensy coastal countryside village for long miles as a means of both transportation and exercise, and speed isn't an issue I'm concerned with. The terrain is varied and contains a fairly equal amount in any direction of steep hills, dirt roads (hard and soft), paved roads, rough/jagged gravel, loose/refined gravel, straight through forestry, beaches, wooden bridges, and some flat stretches of paved roads pocked with the occasional wide crevices.
I have a Granite Peak Roadmaster but riding is excruciating on both the bum and the hands, and I've often noticed the tires going a bit flat under my weight after two or three rides... Should I be looking for a new bike, or just "upgrate" parts like the saddle and tires and purchase some nice gloves?
There seems to be emphasis placed on specialised parts rather than the bikes themselves, but is there such a thing as a bike that has everything I need already installed? Or is it going to be an endeavour of purchasing pieces here and there and assembling them together to "build" my own bike?
Is there any advice you lot can give? I'm really sorry for the tl;dr and complete newbiness of this post, but my head has been all turned around and I'm almost entirely frustrated.
