Our 4iiii Dura Ace R9100 Power Meter Prices

Our aim is to make it as simple as possible to get the best 4iiii Shimano Dura Ace R9100 power meter prices, without having to spend hours trawling the internet. Most comparison sites use data feeds to update their tables automatically, but these aren’t widely available in the cycling world. So where we can’t automate price changes we check sites manually.

Most of our prices are updated on a daily basis, but where we’re performing manual checks there can be delays. If any of our Dura Ace R9100 power meter prices are out of date please let us know in the comments below and we’ll get right on it.

When you click through on one of our 4iiii Dura Ace R9100 power meter deals, and then make a purchase, we sometimes get a commission from the retailer. Not all cycling shops do this, but where they do it has no affect the price you pay for your R9100 power meter and it helps to fund the upkeep of powermeters.cc so that we can continue offering the best power meter price comparison in the UK.
