Shimano DA 7900
 

Yes it is lighter than DA 7800 but has anyone figured out, other than using axle grease on the chain, how to quieten the DA7900 drivetrain down ?? Thanks

I'd make a suggestion, but then folks would accuse me of shilling my stuff.

I'm not familiar with that expression. Please "shill your stuff" if you have a good suggestion re my DA 7900 noise problem Thx

Consider the source since I make it, but Chain-L has a good track record for quieting noisy drivetrains.

You don't have your home area in the profile, so I can't refer you to a dealer, but if you live near any shop that sells Chain-L, drop in and tell them I said they should apply some to your chain for free so you can see if it helps without having to buy first.

All I ask is that you dry wipe (do not wash) your chain first so it's free of any loose dirt and excess oil, so the shop doesn't have to lose time doing that first.

If you're not near a Chain-L dealer, I'll send you a small sample if you'll pay the $2.00 postage.

In addition to FB, what chain are you using? and if you have a Shimano, is it mounted correctly (10 speed road have symmetrical chains) as this can make a difference. Lube would be the first thing though.

I never accuse anyone of "shilling their stuff "if they can fix the problem. Kindá like "it ain't boasting if ya done it " ! I live near Calgary, Alberta, Canada. Maybe continue off forum.

Yes Shimano 7900 chain,installed correctly and I have tried several chain lubes but not Chain-L
