|Anyone know any differences between the Dura-Ace and Ultegra versions, apart from a tiny weight diff? (I assume diff spindle material?). Same bearing design? Shimano web-site doesn't give away too much, and here in the UK, price (at least that I've found) for the DA is about double Ultegra. Comments on the cheaper version?|

|other than the axle and bearings in the DA's, the other differences are very minor, these being, colour, the DA's are a matt finish, the Ultegra's are polished, the only other noticeable one is the DA's have a small lip on the axle housing, whereas the Ultegra's do not.
For your money the Ultegra's are a wiser option, 2 for 1 so to speak, that's what I've done, although there is now a a back order in the UK for them, approx. 2 - 3 weeks before the next delivery to Madison's, so I've been told, good job I got'em when I did!!
Hope this helps.

|Wacky - .....and you like 'em? I'm on bottom-of-the-range Look's and am getting bored with the "vagueness" that comes when the ridiculously soft look cleats start wearing (about 10 miles after replacement!). The SPD-SL cleats are made of slightly harder plastic, aren't they? also, is whatever float there is fairly friction-free?

|Like 'em, no I luv 'em!!..........I've had Look's, creaked too much when climbing/sprinting and yes the cleats wear very quickly, Time's, OK, but kept releasing my feet to often, Pro-Fit's, glorified Look's and the cleats cost too much to replace, not tried the Impact though, although one of my M8's has them, and the cleats look too fragile to me if u're gonna do some cafe stops, SPD's far too small and so caused cramp in the ball of my feet, SPD-R's very good, no complaints really, SPD-SL's, fantastic!, nice large surface area on the polates and pedals, but bring your feet a lot closer to the pedal axle, for better pedalling action.
Technical info below:-)
Distance foot-centre of spindle: 14.4 mm
Adjustment options: fixed (SH10) or 3 degrees of free float either side (SH11, supplied as standard with pedals)
Contact cleat/shoe: 60 mm2
Contact cleat/pedal: 45.1mm2
Cleat material: nylon with rubber stabiliser pad
Re-cleats themselves, very similar to Look's style wise, (yippee, they don't creak when climbing unlike Look's)but have the rubberised stablbiliser pads on the corners and end peices for walking, I've had mine for approx. 3 weeks now, and have had a few, too many, cafe stops, see image below, there's hardly any wear at all, and I'm no tap dancer believe me,i.e. light on my feet, lol.
With regards to float and friction, I've not encountered any problems with regards to the lateral movement, very smooth movement really, at first they feel very slack/loose, i.e. your feet do a side to side dance now and again, but as with everything these days you become accustomed to it.
The standard cleats that are supplied with the pedals, SH11's offer 3 degrees of free float, either side, and if you want Shimano also offer the SH10 fixed cleats, which have red rubber stabilisers for walking on, but I've yet to see them in the UK, not that I'll be wanting them anyway, unless I fit them onto my track iron.
10/10 and that's coming from a Campy fanatic!!
Hope this helps.

|The DA versions must be installed with an 8mm hex wrench, as there are no pedal flats; the Ult. version does have pedal flats. Performance diff? None.|
|Best price on SPD-SL ? ebay or Totalcycling||Maartin|

|Anybody know others ? I worry about Ebay and www.Totalcycling.com is $137 + $16 = $153 which is not bad.|

|Need longer screws than the ones that come with the pedals for use with Sidi shoes. I have to use the phillips head screws that come with the Sidi's but would prefer the Shimano ones with the Allen key head if they were longer.|| |
