Good price for a solid set of composite pedals.
Multiple colors, Reds are $18 which I believe is a new historic low for new items, rest of the colors are $20 (lowest ever was $19).

These are on-par to Raceface Chester & better - IMHO - to the convex Stamp 1. You won't be disappointed, unless you want a larger platform, in which case look into OneUp & PNWs composite pedals.

To each his own ofc, but these and most nylon/composite pedals are pretty strong. Not unbreakable ofc, but neither are alloy flat pedals: I am pretty sure that the vast majority of strikes or crashes that would break a nylon pedal off, would probably break a 7075 alloy one too. I've seen crashes that ended up bending/braking the CrMo spindle (or the threaded portion of it) and the nylon platform survived.

Similalry with pins, that provide all the traction: if you strike a pin hard, you might bend or brake off the relevant pin holding hole on the composite pedal, but most likely that would be the case with the alloy platform, as the steel pins are harder.

The only real disadvantage I can see with nylon is that (flat) nylon pedals are typically a bit thicker than aluminum ones (like 2-3mm), which might lead to more pedal strikes*.

That said, composite pedals dampen vibrations and strikes a bit better - if those happen, and since the color is integral to their mass, even deep scratches are harder to notice on worn examples.


*This is what I believe was what CB tried to address with the super-thin Stamp 1, but led to the spindle housing being thicker vs. the edges, which leads to - IMHO - a weird convex platform where you cannot possibly have equal purchases on the front and rear pins, as the area in the center is almost proud of the pins. The alloy Stamps (3, 7 etc) are flat throughout. CB is not a random company, they seem to be ahead of most things, I just don't like the Stamp 1s.
Thank you.
Although I would highly doubt someone looking at $20 mtb pedals should care saving a couple of grams (or 20).

But if we want to be nit-picking, this rockbros flat has 10 pins per side, the Chester has 8 pins... 25% more pins for just 20 grams, good trade IMHO (and under half the price).

I'm personally not a fan of Nylon pedals for any style of biking.... especially not MTB. An Ankle injury due to a failed pedal after a rock strike or after landing a jump is not worth the half a year to a year of downtime and thousands in medical bills.

Those spikes that grip your shoes leave gnarly scars if you hit em in a wreck. I told people it was a scratch from a bear (obviously joking but it sounded cooler than fell off my bike).

I don't have any injuries from MTBing more than a handful of years, but I do have quite a few "bear" nicks myself. And it is not from wrecks mind you: Simple pedal slips trying a new jump, hopping a new bike or being stubborn on uphill tech, all are more than enough for me.

As a total newbie to mountain biking, are these a good idea to add to my Rockhopper Sport? I don't want the "bear strikes" on my legs. However, I presume the added grips really help with riding?

Not a bad price. My Wellgo mg-1s are 360 but bearings are silky smooth

Pins tore up my gym shoes but that's expected

Good deal, but just bought chesters last week. Caught my alloy ones one the edge, it split my shin like an Easter ham.

One you get "spiked" pedals you'll never go back. Idk how durable these off brand pedals are but my OneUp composite pedals have been amazingly durable. I've broken off a couple pins and the pedal was perfectly fine.

Totally worth it. Pedal bear strikes are as rare as real life bear attacks in my experience.

I've been using a similar pedal (Race Face Chester's) with skateboard shoes for years.

As cheap as these are, it seems to be worth a try.
