If the 0,75mm tip does not drop into the chain link, then the chain is not stretched so it is not worn out.
If the 0,75mm tip drops through the chain link, then the chain is stretched and should be replaced without delay to
prevent premature sprocket wear.
No matter how often you ride your e-bike, it is important to regularly lubricate the chain. When not properly lubricated, the
chain may go bad and compromise your e-bike performance.
Pantera features a Shimano RD M360 8 speed cassette sprocket. Equipped with 126 links chain.
If also the 1mm tip drops through, the it might be too late for a mere chain replacement. This chain stretch level might
mean that cogs and chainrings have been damaged. This case we recommend you see a professional bicycle service
to check it out.
Checking the chain conditions
Chain, cassette and derailleur maintenance
On one end this caliber has a hook to be inserted into a chain link, on the other end there are two tips. The first tip (0,75mm)
measures if the chain wear is equal to or higher than 75%. The second tip (1mm), located on the opposite side, measures if
the chain wear has reached 100%.

The cassette internal gear has several benefits: it allows to change gear even when stationing, which is great when you stop
without downshifting for the next restart; it grants greater cleanliness; the [maintenance] intervals are longer.
Shift gears until triggering the lowest gear so as to get the maximum chain backlash
In order to ensure a high performance, it is essential to constantly monitor your e-bike chain and derailleur.
To check the chain conditions and its possible stretch, we suggest you use a “chain wear indicator” caliber.
