220 Magazine Tri Fit
Matthew Brett the editor of 220 Triathlon magazine is writing a feature on correct bike set-up for triathlon so he paid us a visit.
He underwent the full Cyclefit assessment and the picture shows how he looked at the end of the appointment.
Look out for the full feature in the next issue of 220.
Here are some general notes on triathlon position.
Matt is relaxed and comfortable and riding within his bio-mechanical parameters, the position allows him to ride efficiently and as fast a possible without compromising the transition and the first few miles of the run.
a. Leg extension
145 degrees - based on leg length and hamstring range.
b. Balance
Centre of gravity positioned just in front of bottom bracket.
c. Saddle
Sit bones positioned correctly on saddle, Matthew is not sliding forward on to the nose and de-stabilising the pelvis and reducing power delivery.
d. Cleat position
Cleats moved back on shoe as the forward knee-over-pedal position does not allow foot to dorsiflex easily over the top of the pedal stroke. Cleat position also requires the calf muscles to work less saving them for the run leg.
e. Elbow pads
Positioned just in front of the boney part of the forearm. Pad width adjusted to put elbows within Matt’s frontal profile reducing drag but not too far to create tension in shoulders and inhibit breathing. Bike handling and stability is also considered.
f. Arm position
Upper arm positioned at 90 degrees to torso, so the strong Latissimus Dorsi muscles support the body. Foreams horizontal. Gear levers easily within reach.
Shoulders and upper body relaxed to facilitate efficient breathing.
g. Neck
No hyper extension and therefore tension when holding the head up. Head position can be maintained easily throughout the bike leg. Helmet sits neatly on the back.
h. Open hip angle
Reduces tension in lower back for easier run transition and smooth pedal stroke utilising the glutes as much as possible.
Next installment we will be looking at his pelvic stability and asymmetry.
