Chainring alignment
Interesting for all those of you who struggle with uneven chain tension.
I put a 50T TA standard 1/8 track chainring on my Planet X the other day ( with the Euro-Asia gold sprocket) and could I get good tension? No way. I change to a Sugino and wow! problem solved. Later I tested 3 TA chainrings on the same bike and they were all hopeless and unusable. Indeed the 50T - if it had been ridden - would have thrown the chain off. I contacted TA and this was their reply:
""This model of chainring (Competition track chainring) has been producing for a long time (the ones on the pictures have been produced in 2000 and in 2004). It is a TA entry-level product, and the default you have noticed is “normal”. The appreciation of this kind of chainring depends on the final user’s requirements. Most of the time it is acceptable for the final users, but we fully understand that it could not be acceptable for people who have high requirements.""
I will say that though they are a bit old, they've been in the cupboard, virtually unused. Why on earth produce chainrings that are not round**********??

A lot of lower end rings aren't as round as they should be. If you're paying 50 bucks for a chain ring, it should be an FSA.
