OK I give in

So whats the difference in Shimano SL comopsite pedals and the new composite Ultegra pedals, apart from the logo I cant tell any difference.............apart from the Ultegra pedals Wiggle have for sale look like they have had a sticker placed over the white bit on SLs...............weight is same, everything is the same, so just why the price difference.

The reason I am asking is, when I bought my bike I needed pedals and I was looking at some 105s at 70ish quid, the guy then pointed me to the newer lighter SLs which were £10 dearer but because I had bought the bike a discount would apply, this puts my SL pedals into the Ultegra SL price range but without the sticker now even I am confused...........SLs or Ultegra Sls............over to you.

Don't worry it's just the marketing men at Shimano taking us for fools!

35g IIRC (17.5g per pedal).

So it looks like the axle or the steel footplate then, I have noticed there is more metal on the SL plate than on the Ultegra's

I bought plain SPD-SL for £25 iirc from the Planet X salee and looked at some of the others costing up to £200 more and the wieght savings were only around 35g per pair!

In MTB standards there are rarely any outwardly visible differences, which in itself is a marketing strategy. However, axle quality, and quite often the cheaper versions have plastic bushings instead of bearings, so the more expensive versions are more serviceable and therefore last longer. I suspect the same will be true of road pedals.
