Having a gearing problem with my Giant Full E+1 (2018)

[Toneee]

Hi All,

I hope someone can help, I’ve been having a couple of issues toward the end of my last ride with the chain jumping when peddling in the highest (smallest gear). I decided to fix it today and got my bike out to see what the problem was, only to notice the teeth on the cassette were a bit weird, weird shapes and looks like some were worn but then others had really nice sharp edges and looked brand new.

Does anyone have a picture of the teeth on their giant full e to compare against. (I’ll be honest I didn’t pay much attention when the bike was new to how they looked, just set it up and rode)

Ill try and get a clear picture tomorrow with the rear wheel removed.

Thanks

How many miles? The teeth have a measure of shapes to assist shifting. Its very hard to gauge a cassette for wear by looking at it. At least I can't.

Skipping, can be caused when I new chain is installed on a worn cassette, but it can also be a host of other things, like a bent derailleur hanger, poor derailleur adjustment, or shift cable adjustment.

I once installed a quick link upside down- I think is was a SRAM 12 speed chain- that caused a skip everytime the quick link hit the small cog.

Less than 500km I would say.

I found the original part number of the cassette and found a closeup of the exact same one and the teeth are weird on that too so guess it’s as you said that it’s supposed to be like that
Ill have to check the alignment + adjustments again from scratch tomorrow and see if it makes any difference.

Depending on conditions and use, it is certainly possible to wear out both a cassette and chain, in 500 miles.

In the winter, my chain, if one without hardened pins, will show 5% elongation as low as 300 miles. Winter in Kentucky is wet sticky clay- mandatory cleaning every ride.
