Hi, my Ultegra 67000 front chainrings are worn out and need to be replaced. I could not find the exact model anywhere for sale, but came up with those options:
- SHIMANO 105 5750 - both chainrings are about $50;
- Praxis - a new set can be had for about $120;
- Wickwerks - about $150;
- A new take off 6800 crankset off of ebay - $130.

Being a weekend warrior, I do not necessarily need to squeeze every gram and per-cent for a sake of performance, so trying to figure if it worth paying x2-x3 for premium rings. Also are 105 rings much different from my older ultegra in terms of weight/shifting/durability?
Thanks!
