Road bikes for tall guys I'm looking to find out about any beginner road bikes for tall, and somewhat larger guys. I am currently 6'8" and 305lbs. Been losing weight a lot, so I plan to be somewhere between 250 to 265 sometime soon. I'm curious as to if there are any good bikes for a guy of my size, or if I need to have one custom made.

My previous experience on bikes have been mountain bikes, but nothing too serious (difficult to sprint on those). If anyone could be of some help I'd appreciate it. 

Thank you.
I'm 6 foot 5 or 195cm tall, with a weight of ~93 kg.

The most important thing is to find a frame that fits you - if you try to up-size a small frame, it means long seatposts with lots of leverage into the frame.  I've cracked two frames over time by doing this, and bent seatposts too.

So at its most basic, you need to get the right distance from your saddle-top down to your BB axle.  For me that is 840mm +-10mm.  If I can't get that set on a frame, its too small for me.  Note, I have proportionally longer legs than torso.

Once that's right, reach to the bars is next.  That is set via trial and error, I don't even know what my measurement there is.

At a guess, you're looking for a 60cm frame size or larger.  Rare and expensive, so you may have to take whatever's available.  Start with a used bike and see how it works for you before commissioning a custom bike.

And do let us know how you get on.
