Chain Suck

Postby NoyzSource » Sat Aug 28, 2010 11:59 am

I got some chain suck again the other day. This time I wasn't pedaling hard so the chain didn't get a 90deg twist in it. It happened once on the trail while I was trying to get my feet in the pedals and another time when I shifted from the middle ring to the small ring but wasn't just spinning to get it to shift.

Does this mean I need to get a new middle chain ring up front?

Probably not. Possibly a new chain though. Or possibly just some lube. I said lube. Huh huh.

That was a brand new chain. Only had a few dirt rides on it since Steve fixed it up from the last chain suck.

Then I don't know why it's happening. Some bike / chainring / chain combos are just prone to chainsuck from what I remember when I rode bikes that have those shifter thingies on them. I seem to remember when I ran a shimano chain with my race face crank on my stumpjumper, I was more likely to have chain suck issues. Not sure what you're using for lube either. That could be the issue.

Do you mean you were shifting under load? That will cause it to happen, also is it only in your middle ring shifting to the little, or big to middle as well? I guess it could be the middle ring.

I wasn't shifting under load at that time. I was just spinning the pedals to get it to shift to the lower gear. I had enough momentum to keep moving without pedal power.

It sucks because if I can't trust the bike, I won't ride. Its a mental thing.

Looks like it may be a 6 pack in the stand inspection kinda deal.

Yeah it need looked and and probably taken apart, maybe you have one or two teeth on the chainring that are either bent slightly or have some metal sticking out in a funny way that it will catch the chain and grab on to it and result in chain suck.
