How To Get The Ideal Bike Position | Ask GTN Anything With Magnus Bäckstedt

Published on December 16th 2017


I'm joined by Magnus Backstedt, ex-pro cyclist and former IRONMAN triathlete. Magnus, I gather you now specialise in bike fits. So we've got some great questions from you, the viewers, that we're gonna ask you. We're gonna start off with one that Stan Cauler has sent in on Facebook and Stan is asking: How can one improve the bike fit when changing upgrading parts on the bike? So, changing the parts on the bike, I think the only thing you can really look forward to improve on your fit then is getting more customizable handlebars. Handlebars can move and change in many different ways. Saddles, yes they can be an upgrade in terms of your fit, I also think at that point you need to see someone professional with the right softwares to help you decide whether that actually helps your position so if your pelvic rotation is in the right way, if you actually can take the pressure from that saddle in the right way and maintain a stable position. Next one we have here from Peter York on Twitter: How do you know if your seat is too high? A lot of the time you'll see that your pelvis is rocking on the bike from left to right and if you're gonna go for a very very simple basic measurement of understanding whether your seat is roughly in the right position, just put your heel on the pedal, get someone to hold the bike so you're not standing with your foot on the ground and sort of trying to do it because then you're not actually level on the bike. You need to sit on the bike properly, put both your heels on the bike on the pedals and see if you can just about reach it when it's at it's lowest point. Shawn Farley on Twitter: Does fitting the bike with a shorter stem to better fit your reach measurement negatively impact the handling? That is, is a tri bike with a shorter stem harder to control than one with a longer stem? No, not really. The tri bike tends to be the extension on the skis and where your elbows are placed on the pads that changes how the bike handles. Yes, the longer the stem is, the more stable the bike will be. The harder it is turn it in as far as you need to, you can basically force the bike into a corner and most of the bikes like the one that you have here is on an all integrated sort of system these days so it doesn't make too big a difference. On a road bike, massive difference. Stegin on Twitter saying: How to determine the position where to put the plate of the pedal on your shoes? Now, the easiest way to do this is basically place your foot on a normal sheet of paper, draw a line around the outside of your foot, take and mark the joint of the ball of your foot by your big toe and the same thing on the outside of the- Your fifth metatarsal, your little toe. Yeah, the little toe, yeah. Draw a line between the two and then draw a line from your big toe to the back of your heel and that is the centre the cross that you're getting on that piece of paper is where the centre of the pedal spindle should be underneath your foot basically.
