OVERVIEW Assioma PRO RS is the lightest road power meter pedal available with just 123.5g per pedal. Compatible with Shimano® SPD-SL® cleats, it delivers pro-level performance and over 60 hours of use per charge—no power dropouts. The power spindle, which safely houses all the important electronic parts and battery, is completely sealed and independent from the pedal body. This so-called “split approach” makes it durable, and extremely easy to maintain. Its sleek design, with a q-factor of just +53mm and a stack-height of 10.5mm, makes it perfect to improve performance and achieve results on your road training. The Assioma PRO RS power meter offers ±1% accuracy thanks to the IAV Power System, and the most complete power data reading available with a wealth of advanced metrics. A modular design lets you switch between road and MTB bodies while keeping the same power sensor. The best power meter pedal to train with precision and ride with confidence.

Great service, awesome pedals

Great service from the 360 Cycling team, I ordered the pedals online, best price I could find, and collected them the same day from the Bury store. The pedals were easy to install (the same process as any SPDs), I haven't needed to change my existing Shimano cleats, they were easy to setup and connect to my Garmin head unit. They also measure cadence, so I no longer need the cadence sensor on the crank arm. They 'wake-up' and connect to the head unit as soon as the cranks are rotated, fantastic pedals.

I recommend this product.

Great Service

Great service from 360 Cycling and best price I could find, ordered these pedals online and collected from the store in Bury. Pedals were easy to install and setup and connect to my Garmin head unit. As they measure cadence as well as power, I no longer need the cadence sensor on the crank arm so an added bonus.

I recommend this product.

Excellent power meter pedals

The power meter pedals have been excellent in use. They were easy to setup and sync with my Garmin head unit (Edge 850). There is lots of data to work with. I recommend you either: 1/ analyse this with a coach; 2/ buy a reputable book on power meter training; or 3/ both of the above, in order to get maximum benefit from the pedals. They are very light weight, which is a positive. On first use the pedal does not swing into a helpful clip-in position, but after a few hours of use I am clipping in just like with my old Dura Ace pedals. The only minor issue was the Bluetooth connection to my phone and the Favero app, which was not very stable for registering the pedals. It took 2-3 attempts. The Bluetooth connection does not connect as seamlessly as the Ant+ connection, in my experience, but I predominantly use Ant+ with a Garmin head unit.

I recommend this product.

Excellent quality, used most cx races last year (in the warmup), and a lot of road races this year as well. Also found them quite warm and comfy for just training in.

I recommend this product.

Favero pedal body

Following a crash had to replace the Favero Assioma pedal body and 360cycling had it in stock and at a competitive price. Quick delivery, pedal included new bearings as well. Lots of videos on line to follow to change pedal over - less than 10 minutes. Highly recommend.

I recommend this product.

Technic blue bib shorts

Early days but so far very happy - material of these bibs feel very plush - super comfy pad and the pockets are a nice touch for longer rides. Never had blue bibs before (always black) and I think they look the part. Size xl and true to size. Great customer service as well. For the price will be getting a second pair!

I recommend this product.

Goodbye to restricting chest bands

Big improvement on a chest band , no tight band round your lungs, easier to put on and you don't have to take layers off when you've forgotten to wear it . Easy to operate and switch on / off while on your arm.. Accurate as any chest band.

I recommend this product.

Superb power meter pedals and great value

I shopped around where to buy these in the UK and 360 cycling offer the best deal. Good to support the cause as well. Calibrated the pedals and getting my power reading and left / right %. Helpful after a fracture on one side couple of years ago. Delivered quickly and in perfect condition. Thank you.
