Shimano PD-M324 — Specs & Analysis
Manufacturer specifications, compared against every other pedals in our database. We do not test gear in the field — we measure, verify, and compare.
The long-running dual-sided touring pedal: SPD one side, a wide flat cage the other, 533 g the pair. It is the heaviest pedal on this site and the one that has been quietly doing this job on touring bikes for decades.
The M324 has been on touring bikes for a very long time, and it earns that by being the least clever pedal in this category. SPD on one side, a broad flat cage on the other, and no attempt to be light.
At 533 g the pair it is the heaviest pedal we list, by a margin — 150 g more than Shimano's own EH500 and 178 g more than the OneUp Composite. On a bike carrying camping kit that is not the number that decides anything, but it should be said plainly rather than buried, because it is the one specification where this pedal is clearly last.
What you get for it is a genuinely usable flat side. The cage is wider than the EH500's platform face, which is the difference between a flat side you can ride all day in trainers and one you use to get through a rough section. For a rider whose trip is half road miles and half walking around towns, that is the trade the format exists to make.
It shares the EH500's real advantage: SPD cleats are the most findable small part in cycling. On a long route, the failure mode that matters is the one you cannot fix, and a worn cleat is fixable almost anywhere.
Weight is per pair, from retailer listings, and there is a disagreement worth knowing about: most retailers list 533 g and one lists 515 g. We hold the figure the majority carry. Shimano publishes neither weight on their own storefront. The $80 price is Shimano's own, which for once is what retailers list as MSRP too.
Who Is the Shimano PD-M324 Best For?
Touring riders who want a real flat side and do not care what the pedal weighs. If that describes your riding style, the PD-M324 should be at the top of your shortlist. It sits in the Pedals category alongside 6 other products we track.
How It Compares
At 533g and $80, the PD-M324 is 178g heavier than the lightest option in this category (the OneUp Components Composite Pedal at 355g). The most budget-friendly option is the OneUp Components Composite Pedal at $49.99.
The price-to-weight ratio comes in at $15 per 100g — a reasonable middle ground between performance and value.
What We Like
- +Wide flat cage is genuinely usable in ordinary shoes
- +SPD cleats findable almost anywhere on a long route
- +Long-running design with decades of touring use behind it
- +Manufacturer and retailer agree on the price
Watch Out For
- −The heaviest pedal listed here at 533 g the pair
- −Retailers do not all list the same weight for it
- −Shimano publish no weight themselves
- −Flat cage has no pins, so grip is nothing like a pinned platform
The Bottom Line
We haven't scored the Shimano PD-M324, and neither has anyone else we can cite. It's here for its verified specifications and dimensions, which is what the fit tools run on — a score is an editorial judgement, and we don't hand one out until someone has a basis for it. What this page can tell you is measured: 533g, $80, and how both sit against every other pedals product we track.

How it compares
Against the 7 pedals we hold published specs for.
At 533g the PD-M324 is the heaviest in the category we track, against a category median of 383g.
At $80 it undercuts 4 of 6 of them, against a median of $85. That works out at $15 per 100g — below the $22 median for pedals.
Weight and price come from published specifications. Cost per 100g is a blunt measure — it rewards light gear and says nothing about durability or whether the thing works — so treat it as one input, not a verdict.
