|I have noticed that diffeent people have the outer part of their hamstring(biceps femoris) attached at differnet places on the tibia. Such as Ullrich and Armstrong. Armstrong's is attached lower and Ullrich's is higher. Is this from the development of this muscle or genetic? Mine is attached higher like Ullrich's and you can hardly tell I have a hamstring tendon there.
One more thing, do you need to incorporate hamstring training since this muscle isn't stressed too much while riding?

|Aerobars, weight-weenie downtube shifter and carbon wheels -- by most standards a total bike geek. If he weren't respected for his results I'd almost feel sorry for the guy. :-)

|Yes, Training your hamstrings helps in riding. Especially for long climbs, forthat matter, at high cadence (110-120rpm). Even when standing, good strong hams will help pull back and up on the pedal stroke. Train 'em twice a week all winter long and you'll notice on the bike in the spring.|

|your biceps femoris attaches to your fibula not your tibia and where a muscle attaches to a bone is genetic (and maybe developmental in some sense), certainly not modifiable via training. Most importantly it doesn't matter.
Differences in endurance performance are largely explained by central factors not peripheral. And the peripheral factors matter in the primary muscles, which the hamstrings are not in cycling. At most they serve to redirect/coordinate the motion of the legs, quads and hip extensors provide almost all of the force that matters for propelling your bike. I think it's a common myth that you can pull back or pull up, which would use the hamstrings, but the opposite extensors at the opposite crank will always be more powerful and therefore be applying the power to the crank.

|The hamstrings are essential to a good round pedal stroke. They may not do much between the 11 and 5 o'clock postions but the rest of the stroke certainly uses them.
Spend some time riding one legged on the trainer (1-2 minute int., each leg) or just concentrate on the upward portion of the pedal stroke. Those hammies will be on fire in no time. You'll notice a much more powerfull spin in those pedals.

|One thing a lot of people have a tendency to do is point their toes down during the pedal stroke and although at certain points this is definitely important it lessens the hamstring activation dramatically. In my spin classes I make sure to tell my participants to keep their heels as flat to the floor as possible. It is biomechanically impossible not to ankle during the pedal stroke but while pulling up this emphasizes the use of the hamstrings. Its something I've really been working on as well.
