I am looking at lower end Tourney or TourneyTX since it will not be ridden much.
I am looking at Shimano literature and wondering why they have different RD for 3x7 versus 1x7. Also, the right shifters are different.
I assume I can keep my front same but someone correct me if I'm wrong, and is it worth it to step up to Altus? My son has Tourney on his Trek and it has held up fine.
Thanks in advance.
If it is a sealed bearing Suntour hub it's likely a Sansin. They are prized hubs that unlike Shimano cup/cone hubs will last forever. Specialized even branded the Suntour/Sansin hubs as their own house hubs for a bit. Suntour/Sansin sealed bearing hubs are prized by those BOBish cyclists in the know.
