View Full Version : Component Compatibility?

I need advice.

I have the following components, all new.

1 SH-SLBS77 Shimano Dura Ace Bar End 9 speed Shifters /Set/ DA cables and bosses

1 SH-CNHG73 Shimano LX, 105 Hyperglide Chain for 9 speed

1 SH-RDM510S Shimano Deore Long Cage Rear Derailleur, 9sp

I need to match them up with an 11-34 9spd Ti cassette on my road frame.

I was told by two mechanics that this will work. However, the Shifter specs in the box say that they will only work with DuraAce components. Shimano does not have them in their compatibility charts, and I can't find any Support email for them.

The chainring is 39/53 Shimano 105 crank. If it will accept smaller rings, I'd be happy to go down to 34/50 or whatever. However, I'd just as soon leave it as is.

Will this work? Will the DA shifters index with the 9spd cassette? Will they only work in the Friction mode? I don't want to simply use Friction, and need them to index, as it will be my hill-climbing bike.


Suggestions??

I'm not familiar with the part numbers, but if the shifter really is 9-speed you'll have no problem with the indexing.

The Dura-ace 9-speed shifters will work with *any* Shimano SIS rear derailer. I installed them on my bike and laughed when I saw the "only with Dura-ace" note since the SLBS77 is the *only* 9-speed bar-end shifter Shimano makes and it is used for 9-speed triathlon and touring bikes whether they have Deore, Tiagra, 105, Ultegra, or Dura-ace drive-trains.

The 105 crank can't take an inner ring smaller than 38T.

Yes that setup is fine. Everything is designed to work in the manner you wish it to, regardless of Shimano's marketing jazz.

Btw, it sounds like you have made some nice choices for a touring/climbing road bike

Thank you! I got this old Specialized Allez Epic as an orphan out of a friend's garage. It's kinda old, but it's really pretty. It's just a joy to ride, and theres a lot of really nice climbing as well as long rides. I guess I'm getting pretty attached to it.

I'm putting it all together right now.
