Compatible chain ring for Cube Reaction Hybrid One.

[airingcupboard]

I’m on the hunt for a new chainring for a Cube Reaction One 2022. The bike has a Bosch motor and 38t. Can anyone recommend a drop in replacement or know the specs for this part. Cube haven’t given me any info. I just know it needs to be 10 speed compatible and the chain was an KMC X-10 and is a whole part rather than a ring alone. There is a chain guard. The motor is 4th gen.

Otherwise if anyone knows the offsets / chainline it requires I can go from there.

Thanks.

Direct Mount
Bosch CX ( recognizable by the ISIS shaped centre )
38T
8,9,10,11 Speed
Boost ( 3mm offset/52mm chainline) or Non Boost to match whatever rear hub you have *

*A boost rear hub is 148mm. Non boost is 142mm..............there are also 135 rear hubs. No idea which you have on that bike.
A Boost rear hub is 3mm wider on each side....hence the chainring is offset by 3mm.........the aim is to get a straight chainline when the chain is on the middle rear cassette cog.

Thanks. That’s solid information and gives me an understanding of what to look out for.

It’s a Shimano Deore CS-M4100 Cassette 10-speed 11-42 teeth by the way.

The only importance with regards the cassette is that it is 10 speed. 8/9/10 speed chains are all the same width which is what matters as far as the chainring is concerned..................so for example you do not want a chainring compatible with Eagle/Shimano 12 speed.
