Here is the story...
I just bought a full suspension frame and I am currently missing the following to complete my build:
Crankset & BB (sorta)
I currently have a hardtail and I am going to make it a single speed after my full suspension is build up. The hardtail currently has a set of complete XT 8spd system (M740). A friend mine suggested to buy complete new parts on my new full suspension instead of transferring my 8spd system over is it is old. I am considering if I should do that or just or buy new parts. He said I might run into problems later if I use the 8spd.
If new parts, I am going for complete 2008 Shimano XT M770 Series. It will cost $500 tax included for crankset, bottom bracket, rear dérailleur, cassette, and shifter pods.
Of course budget is an issue here. But $500 isn't too much and I am debating if I should go with new parts or use old parts. I also have an old RaceFace Turbine LP which I can put on my new bike. But my new XT purchase must be in bulk (including the crankset) at that price or is a no deal at all.
What do you guys think...all new or go with old parts?
