Shimano tourney-to-deore
Hi, i've been mountain biking for almost a year know and when i started i bought a schwinn s-40 from my LBS. After six months i was encountering many problems and was wonder if it is worth the money to convert from all shimano tourney to all deore. And how much stonger it is. I don't really want to get a new bike because it will cost less to do the full conversion than to get a new bike.
