The reach to the handlebars is so important because of the static nature of cycling for the upper body, so it’s one of the few sports where there’s such a difference between upper and lower body. The majority of the time you’re in the same position bent over essentially for massive, massive periods, and very static. So if you get that reach wrong, over that amount time it can add up to discomfort and at worst, pain and injuries. Most people’s default position is on the brake levers, obviously that’s where the gear changes doing, that needs to be in people’s comfort.
Zone, if that’s too far away they generally overreach. Most people will bend forward people will have a small bend in their midback and they’ll take up the slack with their shoulders so if the reach is too far away the shoulders bow round, they’re always using their pecs slightly to hold themselves out, very straightarmed, and it means that the connecting muscles, the rhomboids in the shoulder blades are always being stretched and not being used, so over a period of time they get weak, get very tight, and people end up like this. If you’re too far away.
And you’re overreaching, there’s a lack of stability and strength. If you’re going to do something dextrous, for example when you chop an onion at home you do it close in where you’ve got the most control and strength, you don’t do it way out, and it’s the same on the bike, you want to have control and strength so you can handle the bike, change gear, adapt, make small changes descending, this needs always to be close and in your comfort zone. If you’re set in a natural seat position, so we’re talking about having the front of the knee.
How To Perform A Bike Fit Reach And Stem Length For Road Cycling
Over the pedal axle, so that standard position, most people a good balance between aerodynamics and comfort for your average sportive rider is that 45 degree angle. Some people who might be able to move forward more are guys who have more natural flexibility in the chain, which is the hamstrings, glutes and lower back. So part of that is work so flexibility, stretching, and part of it is just a natural ability really, some people are naturally more flexible that others. Occupation is a big factor as well, so people who spend a lot of.
Time in that seated position are more likely to be quite stiff in the hamstrings and also quite stiff it the hip flexors. So we’re talking about back angle of about 40 to 50 degrees on the top of the levers is a good compromise between comfort and aerodynamics. Like I say, Si being expro and being able to handle those lower tolerances from years of riding a bike he’s at the lower end at ‘.3 for his back angle. So what we’re looking at here with Si is keeping that upper arm angle.
At less than 80 degrees, so it stops that rotation of the shoulder blade. So about 90 degrees. Like I say, Si is on the edge of that limit but coming from an expro background he’s got that extreme position but with Si it’s sustainable. So he was at ‘ degrees before, we’re looking to 4050 as a good balance, and Si is getting a little old now and winding it down so actually he does need a bit more comfort going into his older age! So actually going up from ‘ degrees to 43 actually suits the relaxed position,.
It now suits his relaxed style of riding. At 80 degrees, we’ve now brought him to a far more comfortable 76, so taking a little bit of stress off his shoulder blades by bringing that arm back a little bit and also visually you can see that the shoulder blades now the arms have gone back a little bit so we’ve taken a bit of slack off the lower back by coming up a touch and a bit of slack by bringing the shoulders back, but that was quite an extreme change 2cm off the stem,.
