General Cycling Discussion - What size bike do I need?

Hi,

So I'm going to get a road bike soon for commuting and errands, but I don't know what size I need. I'm not sure what stats one needs to size a bike so here goes. I'm 6'1", 210lbs, male, 28yrs, I like moonlit strolls on the beach and I'm looking for a long relationship with the right bike. Can you help me find the right sized bike for me?

Thanks

Punch bicycle sizing into your search engine and you will get many sites like the one above . Bicycle companies sometime measure their frames differently so it's best to pick a bike and get sizing done by your LBS.

I am sure each person will tell you something different, I was told that when straddling my bike I should have 1" between the top tube and my crotch. I am 5'11" with a 32" inseam and ride a 59cm Bianchi .
I would suggest you go to your LBS and have the dealer show you a couple of bikes that he thinks should be in your size with in a cm or two of eachother, I would ride them and see what is more comfortable for you.
I have a Bianchi that is 59cm that has been fitted for me and its very comfortable, But I also have a 61 cm Bianchi that has been fitted for me and I am just as comfortable on that bike aswell tho I dont have the clearance between the top tube and my crotch on the 61cm I still have room if I so need it.
I have seen taller riders on shorter bikes, with a higher seat post, yet i have seen shorter riders on bikes that I am sure they could barely touch the ground if standing on their toes.
I think the keys words you need to know are: What feels good for you, and having the bike adjusted and fitted for you so that the riding doesn't cause discomfort and injury.
Be sure to have the bike professionally fitted. Fitted meaning: everything from your seat adjustment, height, handlebars, pedals etc. You LBS should be able to do this for you for a small fee, but it is definately worth it...
Ride safe and good luck

really, the easiest way way to really figure it out is have someone fit you. You can go to your LBS and have them fit you. For a rough guess, i would say 58-61 but no bigger than a 61.

Good luck!!

You can check out a more general-purpose fitting guide at Peter White Cycles.

For commuting and errands, you may want to consider a road bike with some touring-style features; not neccessarily an expedition touring bike, but one which can accept rack and fenders, and has tyre clearance for 28mm rubber. This usually means a frame designed for longer caliper brakes, rather than short racing ones.
