I agree, be up front with your size and own it. I was probably pushing 290 (& 5'10") at the time I bought mine. I, like my husband, have OCD when it comes to researching a product that I want. I OVERLY did my homework. Kind of have an idea of what you want, go in and talk to them, be open to suggestions, but don't be afraid to question why they are making that suggestion.

Ride the bikes, and don't be afraid to tell them if it doesn't feel right. They should try to make it either fit right or fine another option. At two of the shops I felt like I was squished into an open air sardine can and pretty much left in tears because I felt like a stupid cow. The 3rd shop I went to, was the one my brother used to work at, they had the bike I'd gone to look at (and really wanted) but it was the wrong size, so I tested the same one, a couple of models up, and loved it. It felt right, fit right, felt stable and well made and I felt like even if I never lost a drop of weight, that I wouldn't have to worry about my bike falling apart under me.

Even though I spent twice as much as I had set out to do, I'm happy I did, and I know I have a bike that if I do decide to get more adventurous once I've finished with my back treatments I won't have a bike I've outgrown. I've yet to break any spokes...yet. My husband is 6'5" and not a little guy and has broken many, they are fairly easy to fix and a good shop should have a bike maintenance 101 class.

It is a big step, and I'm excited for you. I still remember the nerves and butterflies I had going into that first shop.

I ride a Specialized Myka Expert, and I LOVE it!
