The Magene PES P515 is a spider-based power meter crankset that offers excellent value at around €220-300, with generally accurate power data (typically within 1-2% of reference sources after calibration), easy installation on Shimano 24mm bottom brackets, and long battery life. However, owners report recurring issues with creaking at the crank-to-spider interface, a left crank arm that can work loose, and occasional firmware problems, while the heavy aluminium crankset and proprietary crank interface limit its appeal for weight-conscious or multi-bike users.

Reviews & Ratings
04:40The reviewer tested the Magene PES P515 Base Power Meter Crankset for a month and found it to be a well-manufactured, accurate budget option. It is an aluminum CNC machined crankset with a 24mm spindle, available in crank lengths from 165mm to 175mm. The power meter can be paired with either the PES aluminum crankset or the Magene KO carbon crankset, and it accepts four-bolt chainrings, including Shimano and other standard chainrings. Priced at $299 USD for the power meter alone, or around $350 with chainrings, it offers good value. The reviewer noted that it reads about 4% higher than Garmin Vector 3 pedals and a Wahoo Kickr Core V2, but after offsetting, the data is quite close. Installation is straightforward but requires careful attention to torque settings to avoid stripping screws. The reviewer recommends it for those who leave their power meter on the bike, not for those who switch often.
16:20The reviewer presents the Magene PES P515 Base Power Meter Crankset as a successor to the P505, which he used for years without issues. He praises its improved design, lighter weight, longer battery life, higher accuracy, and exceptional value for money at €299. He highlights its compatibility with Shimano 24mm bottom brackets and 11-12 speed groupsets, and notes it can be paired with Magene CAD chainrings. He plans to install it on his bike and expects excellent performance.
09:59The reviewer discusses the Magene PES P515 Base Power Meter Crankset after using it for 100-2000 km on a Quota K1 bike. He praises its excellent quality-price ratio, calling it the cheapest power meter crankset on the market at €299, with improved accuracy of around 1% error, lightweight aluminum 7075 construction at 600-620g, and battery life updated to about 320-330 hours. He notes it is reliable, stiff, and widely available in Italy, but mentions the chainrings are only available in Shimano ratios (53/39, 52/36, 50/34) and not yet in 54/40. He recommends it for its performance and value.
13:16The reviewer tested the Magene PES P515 Powermeter-Set, a crank-based power meter that is a more affordable alternative to the pedal-based P715. They found it to be a good power meter that provides accurate and consistent data at a reasonable price, with performance comparable to the more expensive P715 and a smart trainer. The installation process was detailed, and the reviewer highlighted the need for careful handling of plastic parts and proper torque specifications.
17:32The reviewer chose the Magene PES Crank P515 Power Meter after extensive research, comparing it to other power meters like Favero pedals and smart trainers. They highlight its accuracy, dual-sided measurement, and affordability at around €300. The reviewer installed it on their own bike, noting the process is straightforward with basic tools. After 4,500 km of use, they report no issues, no creaking, and improved comfort due to the shorter crank length (170 mm vs. previous 175 mm). They recommend it for cyclists with a single bike who want an accurate, cost-effective power meter.
22:30The reviewer mentions the Magene PES P515 Power Meter Set briefly as part of Magene's product lineup, noting it's an entry-level power meter with an attractive price point.
16:07The reviewer tests and reviews the Magene PES515 power meter, which is a spider-based power meter that comes with a PES crankset. They detail the unboxing, installation on a bike with a Shimano groupset, and extensive testing against other power meters. The reviewer notes the initial accuracy was off by 4-5% compared to their reference pedals, but after applying a calibration offset in the app, it showed excellent precision and repeatability. They conclude it is a very affordable option that requires some user calibration to achieve accuracy.
09:15The reviewer purchased the Magene PES P515 power meter crankset from AliExpress for £225 to improve their winter training. They were greatly impressed with the results and found no downsides. The reviewer found installation straightforward as a direct replacement for their Shimano Ultegra crankset. They tested the power meter's performance against Wahoo Powrlink dual-sided pedals and found the data to be accurate, consistent, and reliable, though it read slightly higher. The crank stiffness was comparable to Ultegra, and the shifting performance of the chainrings was very good, nearly matching Shimano's gold standard. The reviewer concludes it scores really well, especially considering its significantly lower price compared to competitors.
14:02The reviewer discusses the Magene PES Crank P515 Power Meter extensively, highlighting its updates from the previous PES505 model. They mention its compatibility with Shimano standards, improved accuracy, lighter weight, longer battery life, and support for T47 and BB 386 bottom bracket standards. The reviewer compares its data accuracy against their indoor smart trainer and finds it to be reliable, especially during sustained efforts. They also note the importance of proper installation to avoid loose play issues.
A user reports that updating the Magene PES P515 power meter to firmware v0.118 caused it to get stuck at 0W and fail calibration. Magene support provided a force reset method using nRF Connect to send a 'reset' command via the Nordic UART Service. The fix resolved the issue for the original poster, but other users report persistent connectivity problems and bricked units even after the reset. Some users advise against updating, and there are complaints about poor support and app limitations.

The Magene PES P515 is a spider-based power meter on an aluminium 24 mm Shimano-standard crankset with a 110 BCD spider. Owners in the rennrad-news thread rate it as very good value and mostly accurate, typically within a few watts of trainers such as the Tacx Neo. The recurring weakness is the left crank arm, which is held by a single clamp design and works loose for some riders even with threadlocker; one owner gave up and switched to the rebadged GeoID PM500, whose left arm clamps with two bolts. Chainring choice matters: standard Shimano road rings fit and shift best, GRX rings do not fit, and third-party rings can shift worse. The TEO P515 uses the same electronics on carbon arms with a 29 mm DUB spindle (about 425 g vs 625 g). Firmware updates come through the Magene app. Street prices are around 220-240 EUR from AliExpress EU warehouses.
AI Summary
Pros
- Very good value; AliExpress EU-warehouse prices of roughly 220-240 EUR are common, well below Shimano or SRAM power meters.
- Accurate for the price; most owners see readings within 1-2% or a few watts of trainers such as the Tacx Neo.
- Straightforward installation on standard Shimano 24 mm (Hollowtech II) bottom brackets.
more pros in the review
Cons
- The left crank arm can work loose over time; most fix it with correct torque and threadlocker, but at least one owner sold his because it kept loosening despite every tip.
- GRX chainrings do not fit: the 31T inner ring is too small for 110 BCD and the GRX outer ring is bolted from the other side.
- Shifting can suffer with third-party chainrings such as Alugear or Pass Quest; Pass Quest advises not to mix their rings with others.
more cons in the review
Key Points
- Spider-based power meter measuring combined power at the spider, with cadence.
- PES P515: aluminium crank arms, 24 mm Shimano-standard spindle, about 625 g.
- TEO P515: carbon crank arms, 29 mm SRAM DUB spindle, about 425 g; same power electronics as the PES.

The Magene PES P515 is a spider-based power meter crankset (24 mm steel spindle, 110 BCD 4-bolt), the successor to the P505: about 25 g lighter, rated at 1% instead of 1.5%, with active temperature compensation and better T47 compatibility; the carbon TEO version uses a 29 mm spindle. It costs around EUR 250 and is bought from Magene's AliExpress store in Europe or Magene's site in the US, avoiding region-locked Chinese units. Owners find it accurate when calibrated (also with oval rings, thanks to continuous angular velocity measurement), easy to install with a 44 mm 16-notch lockring tool, and compatible with Shimano 105/Ultegra chainrings, GRX and many aftermarket rings; firmware updates (v0.118/v0.119) improved behaviour, though one user saw spikes after updating. The recurring problem is creaking or clicking under load that returns after a few thousand km. Magene says it comes from the crank-to-spider interface, replaced one unit under warranty, and owners silenced it by greasing that interface generously and torquing it fully; others report 4,000 miles without noise. Other niggles: a proprietary crank interface (Magene arms only), early one-piece preload bolts that got lost or stuck, an occasional lockring thread defect, narrow chainring bolt holes that make GRX chainring nuts awkward (Alugear bolts work), lost crank bolt O-rings, spacers needed on some frames, and patchy Bluetooth and customer support. A revised drive-side-bolt crankset was shown in Shanghai.
AI Summary
Pros
- Good value around EUR 250 with 1% claimed accuracy and temperature compensation
- Accurate when calibrated, also with oval chainrings
- Easy installation with standard tools and a 44 mm 16-notch lockring tool
more pros in the review
Cons
- Creaking or clicking under load after a few thousand km, which regreasing only fixes temporarily for some; Magene points to the crank-to-spider interface
- Proprietary crank interface: only Magene arms fit
- Early preload bolts were one-piece and got lost or stuck; replacements are hard to source
more cons in the review
Key Points
- 24 mm steel spindle; 110 BCD 4-bolt spider; TEO carbon version with 29 mm spindle
- About 25 g lighter than P505; claimed 1% accuracy; active temperature compensation
- Compatible with T47 (68 and 86 mm) and Shimano BSA BBs; spacers needed on some frames

Magene P515 : a nice powermeter, works well on my Wahoo Bolt and my Coros Pace. 250€ with coupons
My short experience with P515.
Sale via Ali from the EU shop went very well, delivery took 3-4 days more then expected. Crank looks very good, marginal heavier than the 105. Assembly was also no problem, I ordered it with the QED chainrings. Installation on my Lightcarbon LCR017 was not a big problem, I did however have to add a spacer on the drive side because otherwise there would have been play between the two arms. First 100k tour was also problem-free, recording in. Compared to the power meter pedals seems to be lower in the numbers, maybe still needs to be calibrated. What I also noticed is that the QED chainrings are louder than my 105 crank.
I hope this can help you a little.
Best regards.
