Hi. I have 2 questions.

I run a 10s Deore drivetrain. My cogs are 11-42 and chainring is 30T round. My current chain length is 108 links which works fine. I am upgrading my chainring to a 32T oval. I want to know what will be the required chain length I must use? If it was 32T round, I would use 110 links based on a chain length calculator. But now, it's oval. I don't see any calculator including oval chainring which is a different design. So, I cannot determine what will be the required number of links. Will it be 110 links as I would use for a round chainring?

Second question on bike washing. I used Decathlon bike cleaner. But I see I'm wasting money. I used bathing soap in water before to wash my bike. It worked great. So, do you think any bathing soap or dish washing detergent are good to clean bike?

EDITED: I run x1 drivetrain.

Thank you.
