Two big end bearings
On the pjme website they offer a standard big end bearing or you can upgrade to a tz big end bearing for an extra £10 what's the difference

The TZ is the full GP race bike.
I doubt you will need it. I buy wossner forged rods which come with big ends and you'd like to think they are good quality.
I personally would say just get the normal one or OEM. Really rods and big ends should be replaced as a pair.
