Great advice!!!!!!! Such a positive attitude You will do great Long term outlook. Not feeling sorry for yourself You are a very positive influence Thank you
With the same power/speed, a larger chainring means a larger sprocket. SRAM default large chainring is 48, which max out at about 55km/h. With more teeth on the front, you will use a larger sprocket (=less friction in the chain because it has to move a smaller angle), and you have a straight chainline. And of course, you can ride 70km/h+ downhill while pedaling. The gains seem marginal, but everything counts 😊
@@ralfmimoun2826 I know all this as a cycling coach and engineer ( sorry dont want to sound cocky) but I wonder what changed for Matti. Was the drivetrain misaligned a lot before? Where did this massive gain come from, in research I cannot find it, except maybe some ceramic speed docu. Interesting!
@@gengar678 He might be less cross chaining because he can keep the chain more in a straight line. I think you lose something like 0.8W every ring you go off the "ideal" chain line. Don't quote me on that though but that's what I was told when aero testing by a pro tour rider.
Keep it up! Awesome journey so far! :)
Good luck ! Welcome to the US! :) Enjoy watching your videos and journey!
Good luck. Oceanside is very beautiful, hope you get a chance to relax on the beach some!
Great advice!!!!!!!
Such a positive attitude
You will do great
Long term outlook.
Not feeling sorry for yourself
You are a very positive influence
Thank you
Good luck to US! Will be awesome to follow 😎
Good luck from Germany Matti 👍
Good job ! Thanks for sharing, very inspiring ! Winner attitude !Good luck for both races !
Can you tell us where the Bottle holder for your cockpit is from?
Good luck - think you’ll do very well
Good luck, lets gooo
Good luck bud
Thanks for taking us along! Is the rear bottle holder still legal after the Ironman rule changes though?
Yes got a green light from Ironman so far, but the local race officals in check in will do the final say I hear.🙏🏻
I wish you all the best.
Thank you!
why is it such a game changer?
Can generate much more speed with a bigger chainring 🙏
@@MattiWeitz do you have any physical explanation for this? I assume the gear ratio does not differ from what you could do before?
