I've had a quick search but can't see anything already posted although I would have thought this would be a common query.
I have a Langster with 48:16 gearing that I ride singlespeed for commuting duties. I inherited it from another rider and since I have owned it I have commuted 3,500 km and the freewheel is now feeling a bit graunchy.
A few questions:
Are these serviceable or at least is there a grease port on them? (I'm pretty certain this one is beyond serviceable but it would be useful to know for next time)
Is there a recommendation on what to replace it with and from where?
Is there a noticeable difference between a Shimano 16T single speed freewheel available from Wiggle for £26-99 and a Dicta 16T freewheel from Mango bikes for £7-99?
