Help me choose a derailleur
I want to replace the rear derailleur on my Diamond Back Ascent mountain bike. It is all friction shifting. The freewheel is a Shimano14-18, the chainwheels are Sugino 48-38-48. Suntour bar mount friction shifters. The way I figure it I need a 36T capacity. I am thinking about a Shimano 105, long cage, 10 speed rear derailleur. I found some attractive deals on EBAY :-) Will a 10 speed rear derailleur work OK ? I think as long as the derailleur has enough capacity then it doesn't matter if it is a derailleur for an indexed system ? Unless the derailleur pulley wheels are different ?
thanks,
Bob
