A small but essential replacement part for riders running a Magene PES spider-based power meter who need to re-secure the spider to the crank without replacing the whole power meter.

Overview

Magene's PES line of spider-based power meters uses a conversion-kit style spider that fits onto the crank's spindle interface, held in place by a dedicated lock ring - this is that lock ring, sold as a standalone spare for anyone who's lost, damaged, or simply needs a replacement for the original.

It's a small, purpose-made part rather than a generic fastener: the lock ring is what keeps the spider seated correctly against the crank during installation and under load while riding, so a worn or missing one can show up as play or inconsistent power readings even when the power meter itself is working fine.

It's worth keeping as a spare if you regularly move the spider between crank arms or bikes, or simply as insurance so a damaged or lost lock ring doesn't put your power meter out of action while you wait on a replacement.

Why You'll Like It

A Fix Without a Full Replacement
Solves a lost-or-damaged lock ring issue without needing to send back or replace the entire power meter spider.

Keeps Install Consistent
A correctly seated lock ring helps the spider sit the same way every time it's installed, which matters for consistent power readings.

Inexpensive Insurance
A cheap part to keep on hand if you ever swap the spider between cranks or bikes.

Purpose-Built Fit
Made specifically for Magene's PES spider-based power meter system rather than a generic substitute.

Who Is It For?

This is a practical pickup for anyone already running a Magene PES spider-based power meter who's misplaced the original lock ring, had one get damaged during a crank swap, or simply wants a spare on hand before it becomes a problem mid-season.

It also suits riders or mechanics who regularly move the same power meter spider between crank arms or between bikes - having a spare lock ring on hand avoids a forced pause in training if the original ever gets lost during a swap.

Good to Know

Keep the lock ring with your other small spares - chainring bolts, cleat hardware - so it's easy to find when you're reinstalling the spider.

A quick check of the spider's seating after fitting the lock ring is a good habit before your next ride, especially after any crank swap.
