Why do I keep splipping on my pedals

ageis

Hi I bought myself a norco 7.1 charger 6 weeks ago.

So I have had this bike quite some time but I find occasionally when a pedaling I can feel my foot lift off the pedal. I'm wearing brand new trainers which I've only worn a few times.

Bear in mind this is on the flat not on a rough trail. So how can I prevent myself from doing this?

I prefer not to use spd's as of yet. I'm still a beginner I don't want to have to keep in mind am strapped in.

my pedals look similar to this

What trainers are you using, those pedals won't provide much grip either

You're doing something wrong.

Try putting on a couple of stone, or carrying some old triangular weights in your camel pack.

or get a set of dmr's and some skate shoes.

Is your foot lifting of the pedal at the bottom of your down stroke when pedaling? If so I'd say your seat is set too high. There should be a slight bend in your knee when your leg is extended.

Also those pedals are not at all grippy.

Poor pedals, poor shoes and not keeping a constant pressure on the pedal.

You want pedals that look like this, http://www.superstarcomponents.com/en/delta-evo-pedals.htm

Trainers with plastic soles are no good, soft rubbery soles are.

OP says it was on flat roads. No point in spending on shoes and pedals if the technique is all wrong.

Those pedals will have little if any grip.

DMR V8 pedals will be a big improvement. Also the flatter your soles the better the grip.

That's why I said this, 'not keeping a constant pressure on the pedal.'

Think of turning the foot in circles - push the pedal forward at the top of the stroke, down through the stroke and drag it back with the foot at the bottom then let it be carried back up by the other pedal stroke - mashing them as though you are stopping through mud is inefficient and can lead to you lifting off the pedal. A running shoe and a p of s pedal wont help either but if you are on road you should be able to deal with it.

I had pedals like these on a mountain bike many years ago. You would not believe how bad they are even on the road. There is no grip, they are small and the worst possible shape for stability unless you put foot straps on them which is pointless. Swapped to some normal MTB pedals and the bike changed completely becoming stable and very manoeuvrable.

My tuppence worth is that those pedals are hopeless especially if you have big feet. Ive also found trainers no use whatsoever as they provide no grip whatsoever. Also better with a firmer stiffer sole for more efficient pedalling. Dont have to spend a fortune on proper cycling shoes either. I use Karrimor walking walking shoes from SportsDirect and have had no problems using them

Rat trap pedals are bad enough, with an alloy cage with no sharp peaks they are even worse!

That said, the Giant bikes I rent often have them and I have a pair of trainers with depp lateral groves that sit neatly on the lateral sections making them 'useable'.

Those pedals are terrible, my hybrid came with the same type and even though I only used the bike on the flat and on road but found the pedals offered little grip. Better yet they were still spiky enough make a mess of my shins on a pedal slip.

I've changed pedals which work much better in general although as you'd expect, some shoes have a tread patter which fits better with the pedals than others.

V8's aren't very good for the price. Superstar Nano's are heaps better.

I replaced my stock pedals (very similar to the ones in the photo) with DMR V12s, and the difference is astounding. I largely changed mine because the stock ones were very narrow and so my feet would ache, and also the V12s were orange and matched my paintwork, but it almost feels like a different bike. Not worrying about whether I've got enough purchase on the pedal makes everything even more enjoyable.

I had some basic Cannonade pedals when I bought my bike and found it slippy over rough terrain when pedalling hard. Upgraded to some Shimano saint MX80 flat pedals and had no more problems.

I've played around with footwear and found the flatter the better!

could be technique, if you're riding in a standing position, you should keep your feet tilted slightly backwards, it gives you some stability.
