Really nice pedals. Used SPD-SLs for years and they don't disappoint. These do make the bike feel like an extention of me. Which is nice.Not sure if there is much difference between this and the Ultegra, I went for it for the ability to be slightly closer to the crank, they were on a deal and it was Christmas. In truth I am not nearly good enough to need Dura Ace.

Attention! Possible counterfei

The shape of the rear body and of the metal inserts in the photo above does not match any version of Shimano Dura-Ace - and certainly not the R9100. Buyer beware!

Be aware of the 4 mm extension.

These are Shimano's top of the line clipless pedals. They have the 4 mm extension which is intended for larger frame riders with broad pelvis structure. Unfortunately, I'm not one of those riders. I bought these pedals out of ignorance, but they are very comfortable and sturdy. I'm going back to the regular Dura-Ace pedals, but I'll probably hang on to these, at least for a while.

Different class from other shimano products

These shimano peddles are definitely a different class from other shimano peddles . With other shimano pedles you get movement from side to side , but dura ace range is lighter more engineered , for a more efficient pedal.

Dura Ace 9100 SPD 4mm longer axle Road Pedals

After a recent Bike Fit I was advised my Time RXS pedals Q-factor not correct for my leg / pelvis and had to change pedals to bring out the Q-factor from cranks and recommended Shimano Dura Ace and went for the 4mm longer axle version to achieve a better Q-factor. The pedals are of exceptional build quality, ultra smooth triple bearings and very easy to adjust the cleat tension. The pedals come with standard Blue 2 degrees float cleats and plenty adequate for most cyclists' over the optional 6 degree yellow cleats available. The pedal / cleat platform gives you plenty of stability and Shimano have lowered the cleat to pedal spindle further from previous SPD versions. The triple Cleat Allen bolts are exceptional quality and chrome / hardened finish means tighten ... MoreAfter a recent Bike Fit I was advised my Time RXS pedals Q-factor not correct for my leg / pelvis and had to change pedals to bring out the Q-factor from cranks and recommended Shimano Dura Ace and went for the 4mm longer axle version to achieve a better Q-factor.

The triple Cleat Allen bolts are exceptional quality and chrome / hardened finish means tighten beautifully without any slippage / rounding of heads, compared to other pedal manufacturers fixing bolts. I would highly recommend the Dura Ace 9100 4mm longer pedals and the price was very good to match the exceptional high build quality.

Expect them to last forever

Like most things Dura Ace, these "just work". They are light, they provide a big platform for pedaling, and I expect will be the last pedals I will ever buy. I replaced my original Dura ace pedals, which still worked perfectly, which I gave to an aspiring young racer.

Light, smooth, solid pedal.

Like all Shimano products, they’re very well made and reliable - they work perfectly every time. Are they worth trading up to from Ultegra - probably not, but it’s nice to have them! Lightweight. Strong. The Best Pedal in the market!

Shimano R9100 + 4mm longer axel

My new Shimano R9100 pedals I've only ridden once since it's been very windy. But installing the new R9100 saved me 40 grams from my old Dura-Ace Road SPD pedals. I opted for the 4mm longer axle to stop the inside of my right show from hitting my crank. The R9100 felt lighter from the beginning when I started pedaling and I can feel the difference my pedaling power moves the bike quicker. It maybe pricey for some but the long term ownership of the R9100 will pay for itself.

Smooth and sleek

Wonderfully smooth running pedals. However, the main reason for spending twice what I would normally on pedals was to see how durable dura-ace actually is. Time will tell, but in the meantime I will enjoy these stealthy looking pedals. One note to mention; these come set up tight out of the box so you will probably want to reduce the tension by at least a full 360 turn.

The extra width make excellent pedals perfect for me!

My pelvic structure isnt wide but my feet are! And the extended axles are perfect. Some bike fitters also claim that very narrow pedal Q can cause foot issues for some people.
