RalphVery happy with my purchase, I now have the ability to monitor the power during my ride, this enables me to base my future training around my current FTP.
Mr CrowlePower meter is brilliant, great price too! Just wanted to say what a brilliant service from Merlin Cycles. I ordered the PM for shipping to the UAE. I ordered the PM on Wednesday and it was here in Abu Dhabi on Saturday!! šŸ˜³ Amazing šŸ‘šŸ‘
Mr Smith (RSA)Super accurate! No need to spend extra money on dual measured power meters. No connection problems, seamless integration and calibration with Garmin Headunit.
AM CyclistExcellent product for getting the most out of training ...just wish Iā€™d got a power meter sooner. Easy to use and great connectivity also. As and efficient service from Merlin too.
Mr JefferiesGreat product, enjoying the extra data it provides for my rides. Easy to setup too
GingernetFinally decided to take the plunge and give myself another layer of data to analyse. Easy to fit and set up via the stages app. Linked to a polar V650 computer. Lost connection half way through the first ride but no problems since. Excellent service from Merlin as usual and competitively priced. Pleased with the purchase just don't forget to keep your head up and enjoy the riding as its easy to get too focused on the numbers..
JulesThis arrived quickly, was staightforward to install (just make sure you have a Shimano pre-tensioner tool or similar, very cheap). This was a replacement for my old pedal power meter, which wasn't robust and eventually stopped working; but this crank power meter appears completely robust - so far I'm completely happy with it.
Mr hillGreat product from stages. Got stages on 3 bikes. Work perfect. Great price and service from . Merlin cycles
Uk RoadieI have used stages before so no stranger to them.They are very simple to put on your bike and using the app is easy as well. Ive been racing for years but bought this as i always over train. Once you have your FTP you can set your garmin to link with the Stages and away you go all the data you will ever need!! Obviously this only does your left leg and splits the average for you which unless your riding the tour de france makes very little diffrence to an average rider. Anyway these seem to be popular as could not find them on line anywhere until i saw them here at Merlin great price and on my door step the next day. If your new to power meters you cant go wrong for the price and ease of use the hardest part is learning what all the data means!! good luck and enjoy your cycling.
