Question: Is this for one or a pair?
Document: I put a pair of these on my bike because the old pedals broke. About a month and a half in (roughly 10-20 miles per week), one of the pedals makes a clicking sound when turned and the petals don't rotate as well as the should. I suspect poor quality ball bearings; only fix is new petals, unfortunately.
I've got a box full of bike parts. Lots of pedals in there, where one of the pair wore out. I guess I'm rough on my pedals, as I like to ride in high gears, which can put a lot of stress on them.I've had these pedals on a bike for 2 years, and those years have been filled with lots of hill-climbing. They are solid as they day I bought them.
The difference between plastic pedals and metal pedals is unbelievable. I used to go through regular pedals a pair every two months. Not only the cast pedals are more resistant but also the shoe does not slip on them. They are also a little wider and longer than regular pedals. The one thing to be aware is the bolt size: I got the  inch and needed to find an extension fit to connect to the arm. That small addition makes the pedal stick out one inch.
Really like these platform pedals! Inexpensive and light. Had a $50 pair and these are just as nice. Would recommend these to anyone
pros: adjustable pins, wide, cool shape, and reflectionscon: need re-grease, seriously. but after it this pair of pedals are perfect and run fluently
I put these on a beach cruiser I use to ride to work. Really like how they feel. Sprayed a lot of grease inside them before putting them on my bike. (a wd40 type of product) Because I read some reviews saying they can sieze. The pair I have are fine, not anticipating any problems.
I had a pair of old "standard" metal pedals that were falling apart that I needed to replace. I wanted a new pair that would be tough and durable for my road bike, since I ride a few miles everyday on city streets. Ive had these for over a month and so far they have been amazing.
Large, sturdy metal platforms for your feet.They turn easily.Threads are machined well and they screwed in with no problems.I really like them, and I doubt I will ever have to buy a pair of pedals for this bike again as its just used for neighborhood commuting.Quite certain these pedals will outlive me. Big difference between these and those plastic cheapies some bikes come with.
Excellent pedals. I have the same kind made by Specialized which have taken 4 years of hard city riding in heat and cold, rain and snow, and are still going strong. This set is for an overhaul of a '98 Diamondback hybrid to replace a pair of cheap plastic pedals. I ordered these in the 1/2" size accidentally, which Amazon generously refunded.
I have a mountain bike that had plastic pedals and they were falling apart. I needed an inexpensive pair of pedals that I can rely on. I done my research and these pedals are the best for me. They are well built and easy to install. When I first used the pedals, I noticed that my cycling power improved because my feet gripped the pedals better than the old ones. These pedals will last for years for my purpose of commuting to work and back.
Answer: yes
