you save a load of weight by getting rid of the derailleurs,
Unless you are cycling competitively, I fail to see how this one is in any way significant TBH. You could achieve the same weight loss by having a decent poo before getting on your bike.
the chain works more efficiently, you don't have the chain coming off, and there is practically zero maintenance. None of that clanking either![]()
These points are certainly more sensible and I wouldn't argue with them.

My point still stands though, which is for most people the sacrifice to flexibility probably doesn't stack up against the "added value" of the plus points to a fixed ratio bike.
