How do you sprint while standing? I just can't seem to make a fluid motion on the cranks. When standing, I always end up with the cranks in almost at 6 o'clock position and will have to exert a greater effort to push the upper crank down everytime. I use platform pedals by the way.

sway that bike , brad. let it lean when you pedal and then pull up the leaning side with your corresponding arm You need to pullup and push out on the handle bars so the bike will sway the other way as you pedal . then the counter then pedal then counter then pedal its like a dance. I can sprint standing up but as the word implies only for short distances read more about it in Brian Lopes' and LM's Mastering Mountain Bike Skills book

also learn to spin at higher gear

what gear are you in when sprinting?

also take into consideration that it saps energy..

also note that there is: Sprinting- which is done at the end of a race or to win points during a race (or at the start of a 4X or dual slalom race) and is always done standing up for short bursts... Climbing off the saddle- which I use to actually rest a little bit or stretch while climbing but does not take any more energy than climbing seated. As a matter of fact, I prefer to climb off the saddle most of the time...

the reason you're having to exert more effort on the pedal at the start of the downstroke may be that you're still putting a lot of weight on the rear pedal. lean forward and put more weight on the bars when you're standing to take weight off the trailing leg. a longer stem helps because if you have a short one, there's a chance you'll slam your knee on the bar, shifter or brake lever clamp (ouch!).

-So is off the saddle more efficient when climbing long ascends??

-So is off the saddle more efficient when climbing long ascends?? no, sitting down and pushing a small gear is the most efficient for most people. for steeper climbs, it's typically easier to climb off the saddle as you can use your body weight to put some weight on the pedals.

How do you sprint while standing? I just can't seem to make a fluid motion on the cranks. When standing, I always end up with the cranks in almost at 6 o'clock position and will have to exert a greater effort to push the upper crank down everytime. I use platform pedals by the way. @ Boybi, pardon me. I don't actually get what you mean. Are you saying that when you sprint standing up, the front foot stops at the 6 o'clock position & the back foot has a hard time pedalling forward?

Ferds, I think his problem is ...he s like climbing stairs when he pedals standing up..tumutokod at dehins bilog (not biosphere ;D) It happens when the bike is upright and he doesnt go forward on the cockpit; or wrong size (too tall for him) ; wrong pedal style I suggested that he leans his bike and sway back and forth while he pedals

Oh, okay. Yep, you're right, Alpha. He's not spinning, ergo di nga bilog.
@ Boybi, Alphabolt's right. Let the bike sway from side to side. When you're sprinting, you're upper body needs to actually work with your legs. You will be pulling on the bars a bit but not so much that you're pulling the front wheel up high. You're just countering the pedal stroke to keep the rear tire digging in for traction.
But I think you might want to work on keeping your pedalling in a circular motion. Like what Alpha said, you might be pedalling like you're walking up the stairs. Your leg's pedal stroke shouldn't end when the foot is at 6 o'clock. It should go past 6 o'clock - like a follow through - to also help the other leg initiate its pedal stroke.

At a steady pace up a climb, I usually spin a bit, when I need to stand, I drop my gearing by one cog and then stand up. Just before the all out sprint, I build up speed and drop another cog, and another if the situation warrants it. I can't spin too fast while standing, I'd rather mash all the way to the finish.

Use Clipless pedals or toe clips? ;D

It's been awhile since I've used platforms Sa clipless , I've learned to focus on pulling up on the pedals and let my weight do the pushing down It lessens the load on my weak knees and makes the pedaling motion more fluid I dont pull on the bars but ley the smooth pedaling action sway the bike naks! Dont know if it works on mtbs and healthy knees Wach Lance on youtube climb the Alps while pedaling smoothly
edit -I'm taking about standing above. I've also noticed pulling up sa pedals when standing lessens the bob sa fs bikes for me
