Just replaced the drivetrain on my converted singlespeed bike - new chain, chainring, cog, tensioner and freehub, alignment seems to be spot on but it seems to be slipping when I put any real force on the peddles. It runs smoothly when the bike is upside-down, and everything seems to be bedding down nicely.
I got the kit from Charlie the Bikemonger > [url= http://www.charliethebikemonger.com/userimages/procart2.htm ]the first one on the page[/url] and a half decent Surley chain ring
I've run out of ideas. Has anyone had any experience of this / any suggestions?
cheers,
Jon
Check the alignment of everything (including the tensioner), then check if again.
Loose chainring bolts are also a possibility, or a chainring which isn't straight? Is the lockring on the spacers set tightened up enough?
Clutches at straws a bit here!
Can you remove a link from the chain to get a bit more tension?
Worked for me when I had the same symptoms.....
Stiff link or two maybe?
thanks pixelmix - I'll double check. The chainring bolts seem tight - there is no play at all, although they only tighten up so much before the whole thing moves around inside the hole - I probably need a tool to hold the nut while I tighten the Alan bolt.
benz - the chain seems pretty tense already, and it's a sprung tensioner, but I may give that a try and see if it helps.
Knackered pawls in the freewheel?

it's a shimano freehub which I got replaced today, but it did make any difference - I must admit that was my first thought, as I had similar problems before and that sorted it out.
not enough chain contact with the rear sprocket? try losing a link to create more.
thanks guys. Definitely worth trying to remove a link - see if that helps.
