So I don’t know what I’m missing out on.
Or maybe it’s just a case of “If it ain’t broke, don’t fix it”.
Plus it's much easier to use one cleat system across multiple bikes.
I’ve ridden with many others using roadie pedals who have:-
- Had major problems clipping in/out.
- Exacerbated the above problems after a short walk through some mud or dirt.
- Incurred pedal or cleat wear much faster than my SPD’s, resulting in their cleat not locking in properly.
I weigh 70kg and have done a few long road rides of around 300km using SPD’s and standard Shimano road shoes.
It’s always been ok, apart from the expected sore bum/legs/feet, which I think would occur no matter what cleat system was used.

I'll take the full 3D sphere of angles thanks. Like I've said previously your application of stress(pressure) distribution has validity through a uniform material. But we aren't dealing with that here are we?richbee wrote:If you don't like a simple 45 degrees, pick any angle you fancy, I'm sure there's a range for every material you and I can think of.
Throw it all into your favorite FEA software of you choice and with materials of difference stiffnesses and of varied geometry and you angle argument quickly disappears from view.
Likewise treat it as a structure as discussed and you angle argument quickly disappears.
Exactly. Better yet draw the 45degree line from the pedal spinal. And suddenly the argument regarding the differences between SPD and SPD-SL disappears.Trevtassie wrote:Is pretty simple, trying to pedal a bike with your bare foot using a surface area the size of an SPD cleat plus the additional surface area subtended by a 45 degree line from the edge of the cleat to the top of the sole would be very uncomfortable. So bugger me if the sole isn't acting as a beam, what with the fibre, moulded box beams and stuff.
A little bit of common sense goes a long way. That and riding on SPD pedals in dunlop volleys. Also I'm damn glad my seat also doesn't behave like the previously described 45degree rule!
Of course like I've stated there is a basis for richbee's claims. But it is being incorrectly applied.

I just bought PD-A600 pedals and they are quite stiff, we'll see how they go after a few KMs.

My only issue is I probably look a little silly with grippy shoes on my race bike lol.
Though in reality, on my road rides I have had comments about my pedals but never the shoes.
I guess people check out my bike more than they do me ha ha.

I can see I'm not going to get a civil response from the likes of you and your self important ego. If your only desire is to belittle others then I see what sort of a person you are. I'd love to enlighten you on the principles of contact stress and pressure distribution as you are clearly lacking in this area, but I can see that you will only respond with glib statements and hide behind your own ignorance.human909 wrote: Of course like I've stated there is a basis for richbee's claims.

Good day, I have nothing more to say to you.

I believe I have been quite civil and this certainly has nothing to do with ego. I would readily discussed this further in a civil manner. I will continue to refrain from making things personal, I'd appreciate if you respond in kind.richbee wrote:I can see I'm not going to get a civil response from the likes of you and your self important ego.
I'm sorry if you have felt this way. I don't believe I have belittled yourself or anybody else here. I have pointed out factual inaccuracies in your statements. You should not find such responses belittling.richbee wrote:If your only desire is to belittle others then I see what sort of a person you are.
Please do enlighten me if you feel my understanding is incomplete. However before you do so I suggest you have a read through what has been written and reconsider the arguments made.richbee wrote:I'd love to enlighten you on the principles of contact stress and pressure distribution as you are clearly lacking in this area, but I can see that you will only respond with glib statements and hide behind your own ignorance.

I would say something is seriously wrong with professionals (of any sort) if they can't have a polite conversation to resolve their different professional judgments. I have no desire to belittle you nor do I have a desire to ignore a discussion. I learn from most discussions which is why I have them.
Like I have said. I could readily construct a scenario where contact stress and pressure distribution goes at all angles. A bridge is an excellent one. Using basic highschool vector force diagrams we can quickly construct examples that contradict what you've stated.

I found it so dangerous that I went back to SPD's. Is this an expected problem with new SPD-SL pedals?

There is definitely a learning curve. Some people end up being able to clip in really easily overtime others not from what I have seen.AndrewCowley wrote:I found it so dangerous that I went back to SPD's. Is this an expected problem with new SPD-SL pedals?
But I can't possibly think that it will ever be easier than spd's.

Personally I have Eggbeaters on my mountain bike and both my road bikes. They are even easier to use than SPDs.

I remember 105 pedals sometimes used to do that when brand new, but I don't remember the Ultegra ones or Dura Ace doing that. I don't really think they are dangerous. All of my bikes have one form or another of those pedals and the shoes I use have the Shimano blue cleats.AndrewCowley wrote:I tried SPD-SL's on my commute bike but found it really hard. When at rest the pedals wouldn't sit at the correct angle to make the clip-in easy. I was using new Shimano PD-R550 pedals (a step below the 105's) and the problem seemed to be that they didn't spin freely enough to allow the weighting in the pedal to do it's job.

The trick is to get clipped in with one foot (the one you start off with) and be in an appropriate gear to allow you to get some reasonable speed going and then once you are moving, clip in on the other side. If at first it doesn't work, you can just rest your shoe on top of the pedal and pedal like that until you have more time to properly clip in or flip the pedal over. You are already clipped in with the other foot so you'll get decent power that way and if absolutely necessary you could also pedal with just one leg (which can be handy sometimes if you end up with a muscle cramp/injury).

Personally, I went for them because I didn't know anything about pedals. They were there; I bought them, used them and got used to them. Without the benefit of googling, webbing or foruming. I'd probably do things different now, but they work, and to change means an unnecessary spend. FWIW, I learned on my commute, in CBD traffic as well as paths.

A simple way to not get involved in a argument is not to respond and that's also smart as if there is discussion going back and forward its way too hard for me to judge, its way easier just to ban everyone[/mod]

Can't tell what pedals they are though.Mr Clear said his fall was only minor and occurred after his foot slipped on the bike pedal when he was about to start moving, causing him to lose his balance.

I am too retro obviously. Crank Bros on MTB and Campy on the road bikes. And toe-clips & cleats on my vintage bikes.

I never appreciated the ease of walking in that SPD shoes allow until I walked in SPD-SL's today and had to do the penguin walking on hot coals walk.
Keep and eye on the trading section for some used and very cheap Shimano road and tri shoes.

- MTB: Flats - I need to chuck the bike when I want to. I've done some longer endurance rides with cleats but I've stopped since the mud clags badly - much easier with flats.
- Commute: SPD because it's jsut easy
- Roadie: SPD-SL Only because it's lighter. If they made spd in carbon at equivalent weights, I'd be all over it.
- Track: SPD. I'd run red cleats here, but only have one pair of road shoes.

80g difference between the XT and Ultegra pedals. Not sure about the weights of the cleats however we are talking bees whiskers here.Calvin27 wrote:Me 4c:

XTR- 310g

What kind of cycling are you doing? If just general road riding I would go with the RP2 shoes (what size are you? I have an almost brand new pair here) and the standard SPD SL pedals.firemac71 wrote:Im new to road cycling and was wondering what would be the better setup for a newbie - http://www.this link is broken.au/shimano-rt82-touring-shoes/
