Magene PES P505/P515 Power Meter Crankset - ±1% Accuracy, 625g Lightweight, 330H Battery, 110BCD, ANT+/Bluetooth, IPX7 Waterproof for Cycling

I've been using this close to a year now and it works flawlessly. Installation was easy enough for an amateur home mechanic to do. It is accurate and consistent. Battery lasts a LONG time; I have charged it maybe 2-3 times in the past year and it's never died on me. Fits Shimano 105 chainrings perfectly. I can absolutely recommend this product.

Competitively priced and amazing quality. +1- accuracy. No complaints and seamless fit with Shimano 24mm spindle. Swap and play!

I received it yesterday , i have Scott addict with shimano 105 drivetrain . My bike mechanic installed it for me without any problems , he used the original shimano chainrings . I charged the meter , downloaded the app and requested the code several times without receiving a response . Finally i checked the junk mail folder and found the code. After a few attempts the app found the power meter . I took it on one ride , it updated quite rapidly , I hit 400 watts going up hills but only for a few seconds before i started to slow down . Now i will ride the watts to keep my rides intense . I also have a very accurate estimate of the calories burned . So far I love it . I will be updating . Too bad I can’t figure out how to get a few extra charging cords . I may have to call Magene . Magene responded to my email with a link showing where to buy extra charging cables, I ordered 2 for my piece of mind , it will be shipped from china . I think they should ship the power meter with an extra charging cable . I did my second ride today with the power meter , it functioned flawlessly , it updated quickly , it showed 100-150 watts on level roads , 250-300 watts with the slightest hills . My Cyclemeter app paired easily with the power meter , it shows that battery level is still 100% after 2 rides . The power meter paired easily with my Garmin edge 830 , I created a data screen showing watts and cadence , along with radar and wind data . I hate clutter . So far so good .

The design, construction and performance of this power meter are on par with products 100% or more expensive. We now have to wait and see how it stands to everyday use. If it lasts 3 to 5 years, this is an excellent choice, especially if there is a need for various power meters for different bikes. Assembles with no fuss, connects immediately with your cycle computer. If you have Shimano GRX, you may have to order a 110 bcd for the smaller ring. Usually GRX has a 30 tooth smaller chain ring which is a 96 bcd. The smallest 110 bcd that will fit in the Magene spider is a 34 tooth chain ring.

4mo update. I’ve tested this against my Favero pedals, Kickr and power is dead on with the other power sources, I’ve also had zero issues or drops. This powermeter is amazing, best value out there I switched from a Quarq to this and I’m blown away at how good it is. Power matches my 2 Quarqs perfectly. Zero offset is stable with no drift. The only recommendation I have is to pay close attention to the install instructions, while it looks like a standard shimano crank install there are 3 specific steps for tightening down the crankset that need to be followed closley

Thus far I’ve put on around 600 miles with these cranks and all is going well. As I already had a Shimano bottom bracket and crankset the move to the Magene PES P505 power meter was simple: remove the old Shimano crank, assemble the PES crankset, move over the chainrings (with their Shimano bolts), tighten everything to proper torque specifications, and go! After approximately 100 miles of riding, re-check torque - all good! I used a known-good set of Favero Assioma power meter pedals to compare readings and the Magene unit was within 0.5-1 percent in terms of power readings - so basically a 1:1 equivalent. You will need a flat interface, open-ended external bottom bracket wrench to install the power meter spider on the crankarms - worth buying at the same time as the cranks if one isn’t in the tool kit already. And if you need chainrings the Magene ones are good, tho Shimano 4-bolt 110mm BCD units for recent vintage 105/Ultegra/Dura-Ace work well and probably shift better - you’ll need Shimano’s bolts if not moving them from an existing Shimano crankset. Also: be sure to use blue thread locking compound on the chainring bolts and the power meter spider, and lightly grease the left crankarm to crank axle interface (or use nickel-based anti-seize fluid). The bolt on the left crankarm has blue thread locker pre-applied. And be sure to double-check torque values after around 100 miles of “bed in” as things can loosen with use. Otherwise: it is a solid crankset for a bargain price, easily as good as a SRAM/Quarq unit.

Lasted 8 months. Worked great and then the crank started to wobble. Went to the bike shop multiple times and no matter how much they tried to tighten the crank it kept loosening on every ride until the shifting became impossible. Went online and apparently other people have had this issue. Will contact Magene and see if there is a way to resolve this issue. Will update if I hear back from them.

Misuratore molto facile da montare e le corone Shimano si adattano alla perfezione. Montato in meno di 20 minuti, molto rigide le pedivelle, misuratore preciso e scaricando i percorsi sul Bryton si notano molti dati in più riguardo la potenza. Unico accorgimento stringere bene la brugola della pedivella e non riesco ad associare il conta pedalate della guarnitura. Comunque sia qualità prezzo imbattibile.

Der Magene PES P505 hat meine Erwartungen absolut übertroffen. Die Montage war überraschend einfach – auch ohne Profi-Werkstatt ließ sich das Powermeter problemlos anbringen. Alle Teile passen perfekt, und die beiliegende Anleitung ist klar verständlich. Was mich besonders überzeugt hat, ist die stabile und schnelle Konnektivität. Sowohl mit meinem Radcomputer (ANT+) als auch mit der Trainings-App auf dem Smartphone (Bluetooth) gab es keinerlei Verbindungsprobleme. Die Datenübertragung ist zuverlässig und präzise – genau das, was man sich für effektives Training wünscht. Auch optisch macht das Powermeter einen hochwertigen Eindruck, und bei den ersten Ausfahrten hat es sich direkt bewährt. Wer ein zuverlässiges und preislich faires Powermeter sucht, ist mit dem Magene P505 bestens beraten. Klare Empfehlung für ambitionierte Hobbysportler und Trainings-Enthusiasten!

13年選手のMADONE4に装着しましたが問題なく使用できています。 固定ローラーのパワーともほぼ同一の数値が出ており精度も良いようです。 取り付けも自分でやりましたが、ネット上の動画やマニュアルを見ながらできました。BBレンチとトルクレンチは必須です。

Molto felice di questo acquisto. Acquistata x sostituire una shimano ultegra. Compatibilità perfetta con il movimento centrale, avendo perno da 24 mm. Le corone shimano ultegra sono compatibili perché hanno girobulloni da 110 e 4 viti . Si installa in breve tempo con pochi attrezzi. Potrebbe servire una chiave specifica per i movimenti centrali per avvitare la ghiera interna che regge lo spider ma volendo si può avvitare con un altro attrezzo perché viene fornita con un adattatore proprio per quella ghiera. Io l’ho montata senza dinamometrica seguendo le istruzioni fornite. Basta un po di esperienza. Va attivata attraverso la sua app che serve anche per la calibrazione ed eventuali impostazioni. Fornisce dati di potenza, cadenza e bilanciamento destro sinistro.

Werkt zoals het hoort. Nauwkeurige weergave, simpele installatie. 1 tip, gebruik op iedere draad eigen Loctite. De vooraf aangebrachte verkruimelde bij monteren al.
