Road verses MTB pedals????(11 posts)

Road verses MTB pedals????Greek Bastard
Jul 15, 2002 6:21 AM
Just purchased a used road bike with Time Equipe pedals. I have been using mtb pedals on my old road bike and am wondering if I should purchase shoes and cleats to use on the new setup. The thought of walking on plastic cleats sort of annoys me but maybe it's worth if from a performance standpoint? Thanks for your guidance.
what sort of performance gains are you expecting?SteveO

Stick with the MTB if thats what you have.

To most people there will not be a noticable difference between MTB and road pedals.

+Road shoes tend to be stiffer than most MTB shoes
+Many prefer the larger platform of most road pedals
-Road pedals usually clip from one side only - MTB both

I think you should just ride what you are comfortable with. If your clipped in and spinning properly you are getting the job done no matter what pedal you're using. I would just recommend getting a shoe that has a nice stiff soul.

Otherwise just use the MTB...The road pedals will likely be a largerplatform and have more cornering clearance which can be important for crits. Probably also better retention which is a big plus for sprints. Not much fun coming out of a pedal at 40MPH.
How heavy are your MTB pedals?Kristin

This was a big difference to me. Shedded nearly a pound from my pedals. As a weak rider, I've been trying to figure out why .75 pounds would make such a big difference. I think its because I wasn't just turning the cranks, I was dragging that heavy pedal through the upstroke.
MTB pedals often cheaper - and lighteroff roadie

Its easy to find cheap ($30-$40) MTB pedals that weigh less than 350 grams. My impresion is that average road pedals start at $50 ands usually weigh close to 400 grams. I think this is mostly because a double sided entry isn't any harder to make than single sided, and because the large / aero "platform" on a road pedal requires more metal.

That heavy pedal is counter weighted by an equally heavy pedal diametrically opposed so spinning a steady cadence in theory it won't matter. The reason is rotational inertia is a significant factor in bicycle acceleration. Lighter rims are the biggest win, the next are pedals. And since cadence amongst most riders is rarely steady lightening the pedals yields a noticeable energy savings.

Rotational inertia is NOT a significant factor in bicycle acceleration. The acceleration that is seen on a bike is really very low. You can test this by putting the bike on a stand or upside down and spinning the cranks in the highest gear. You will be able to accelerate the rear wheel up to 40-50 mph with just a few quick turns of the crank. The resistance to this acceleration, which probably at least 10 times the acceleration that you will see on the bike, is minimal. That should be convincing... If not let me, do a google groups search for "acceleration rotating mass jobst".

My first clipless pedals were SPD mountain pedals, which I got so I could wear mountain bike shoes and walk with cleats on. I switched to Looks about a year later because the larger platform is more comfortable on longer rides. However, I recently reinstalled the SPDs on a long, multi-day tour for the convenience of walking. I was surprised at how well the SPDs worked and it was certainly more convenient than my Looks. SPDs w/ mountain bike shoes is a very convenient combination when you are on tours -- making a lot of stops, walking around at lunch time, etc. The main advantage of the Looks, to me, is that they are much easier to clip in and out of than the SPDs, with which I often have to hunt around to properly click-in after stopping at lights, etc. I am glad I hung onto my SPDs, though, and will probably continue to use them on tours.
Thanks very much for your thoughts.....Greek Bastard

I am more of a mountain bike enthusiast and your input really helps. I frequent a mountain bike website where a question like mine would have been totally flamed with smart ass responses. Refreshing to see constructive posts via this road bike forum.
how much walking?KenS

MTB cleats are recessed under the lugs on the shoes while road pedal cleats are exposed, and more likely to suffer damage when walking about. I stuck with using ATACs.
