A new Shimano Dura-Ace 9300 groupset is just around the corner – although just how far around the corner we can’t tell you – and the latest confirmation comes from a now-deleted Instagram post that shows Dura-Ace PD-R9300 pedals and a caption that suggests the stack height will be as low as just 12.5mm.

It’s pretty much common knowledge that the top-level Dura-Ace groupset is coming soon. It has been spotted at the Vuelta a España, and only last week we reported on leaked pictures that apparently show the new shifters, rear derailleur and power meter.

Now we’ve had someone sending screenshots of a since-deleted Instagram post from Dutch bike shop Handmade Weesp.
The pics show pedals and packaging marked PD-R9300 – which is exactly what we’d expect next-generation Dura-Ace pedals to be called, so that checks out.

What can we glean from the pictures? First, notice the packaging: it says ‘Dura-Ace SPD-SLR’. Does that simply indicate an update of the existing SPD-SL system – perhaps a lighter version? Or is SPD-SLR an entirely new – and possibly incompatible – system?
Remember back at this year’s Paris-Roubaix when Mathieu van der Poel, using Shimano SPD-SL cleats/pedals had a mechanical and tried to swap bikes with teammate Jasper Philipsen? He couldn’t clip in and had to abandon the idea because Philipsen was using prototype cleats/pedals. That would lend weight to the idea that the new SPD-SLR system is incompatible with existing SPD-SL.
The SPD-SLR pedals and cleats shown in these pictures certainly look very much like SPD-SL, but are they identical?

Not quite. For a start, there doesn’t seem to be any fore/aft adjustment available on the cleats. With SPD-SL, the holes in the cleats are rectangular so you can shift them forwards and backwards to get them positioned exactly where you want them on the sole of your shoe.
The cleats shown here appear to be square, suggesting that you’re not going to have any wiggle room for fine-tuning their position – or, at least, very little.
What can we tell from the pedals themselves? Not a whole lot, to be honest, other than that Shimano seems to have got rid of the central section of stainless-steel plate that protects the carbon-fibre composite pedal body, which is a feature of the current Dura-Ace PD-R9100 SPD-SL pedal (this isn’t a feature of all current SPD-SL pedals).

Beyond that, things look very similar to before. Interestingly, Google Translate suggests that the Insta caption says that the stack height of the new pedals is as low as 12.5mm. It’s 14.6mm on current Dura-Ace PD-R9100 SPD-SL pedals.
We heard a lot about pedal stack height last year when Q36.5 and SRM launched their pedal/shoe combo with a distance of 9.7mm from the centre of the pedal to the top of the cleat, claiming that this was “the most direct and efficient power transfer on the market”.
It’ll be interesting to hear Shimano’s claims when these pedals are officially launched.
When will that be? Sorry, we can’t help you with that one. The presence of these pics on Insta suggests that they’re already being delivered to retailers, but we could have misinterpreted that.
And bear in mind that Shimano won’t necessarily release Dura-Ace pedals at the same time as the rest of its new Dura-Ace components. It has already released Dura-Ace WH-R9370 wheels, for example. The various components usually come to market at the same time, but not always.
Stay tuned for more details as and when we get them.
