Frequently Asked Questions
Q: Are the PROMEND M29 and R27 bike pedals compatible with all bicycles?
A: Both the M29 and R27 pedals feature a standard 9/16" threaded axle, making them compatible with the vast majority of road bikes, mountain bikes (MTB), and folding bikes. Always verify your bike's crank arm thread size before purchasing.
Q: Why do my new R27 DU bearing pedals feel stiff or hard to spin?
A: This is completely normal for DU bearing pedals. The R27 uses DU (sleeve) bearings which can feel firm when brand new. After a short break-in riding period, the bearings will loosen up and rotation will become noticeably smoother. This is a characteristic of DU-type bearings and not a defect.
Q: What is the difference between the M29 and R27 models?
A: The M29 is slightly larger (123 × 110 mm) and heavier (~310g/pair) with a Chrome Molybdenum steel axle, making it well-suited for more demanding MTB and trail use. The R27 is more compact (105 × 94 mm) and lighter (~260g/pair) with a DU bearing system, designed for daily leisure and road riding.
Q: How do I install PROMEND flat bike pedals?
A: Installation is straightforward using a standard pedal wrench or 8mm hex key. The right pedal threads clockwise (standard) and the left pedal threads counter-clockwise. Apply a small amount of grease to the threads before installation for best results.
