I used a different system before but the SPD-SL are superior. They allow for a more natural feet movement, so I don't feel any strain after long rides. The platform is large and thus the force is not applied just to a single point in the middle of the foot. I could even ride in regular shoes, if I need to hop on my bike to run an errand. I just have to flip the pedals over.
Clipping in is more difficult than with my previous system - sometimes I can't find the right position quickly when starting from a traffic light. But that is a minor inconvenience and something I will probably get better at with time.
I swapped these in on my commuter bike this winter to replace some nice Crank Brother Eggbeaters. I thought those mountain pedals would be easier to get in and out of, but I think the 105 road pedals are better. I like they way they're always positioned for clipping in.
These compare just fine to the Dura Ace pedals on my road bike. Maybe not quite as light but great for the price and knowing that I'll have them out in rougher daily commuting conditions.
Perfect pedal for the price.
All components on my gravel-beater commuter bike are Ultegra but 105's are good alternatives that don't add much weight and still quite a bit less than Ultegra. Also, given how much the pedals get beat up, it seemed like the right call.
Honestly, the difference is pretty small. Main difference I see is the steel vs stainless spindle and a few more grams. They are a little stiff out of the box-but 100 miles or so in and they spin as nice as my Ultegras
Bought this pedal to upgrade my triathlon bike didn't want to break the bank so I didn't go all carbon. I felt the pedal was a high performer at a great value, and I feel like I'm getting more power output from my bike.
Being relatively new to cycling i was looking for quality components without breaking the bank. These pedals fit the bill. I put them on my new Trek Domane myself. They were easy to adjust. I am well pleased with them.
