Drive train problem, need help identifing the problem
It happened this morning while riding. Standing while pedaling and suddenly it was like there was no chain, but only for a second. Then there was tension on the chain again.
This happened several times through out the ride and seems to get worse as the ride went on.
Is this a freewheel problem?
thanks for your help

This has happened to me only twice. Once when it was -5 deg outside and the pawls wouldn't engage, but it's summer now. The second time it was because of worn-to-nubs teeth on my chainring causing slippage.

ok a LBS mechanic thinks it is just a badly streched cable and worn chain. The chain only has 1,000 but we did find a link that is about to come apart.
So a new chain, new shift cable and housings. Should have the bike back midday tomorrow.

As a warning, you might need to still replace the cogset... I had a bike with 600 miles or so on the original chain and cassette, built a new wheelset with a new casseteand put another 400 or so on THAT.... Out of habit I replaced the chain since it was showing signs of wear.... It actually -caused- more problems because of the classic 'new chain, worn sprockets' problem... Especially in the case of 9 speed drivetrains, I know a lot of people who replace their chain every 800 miles or so.
