Q-ring/front derailleur issue

[castlerobber]

I would order the Pedro's equivalent asap and wait til you have it to try re-doing your Yaw.

I went by the LBS this afternoon to see whether, perchance, they had a fourth-hand cable puller for sale (they didn't). I told my usual mechanic about the chain rub, and how I planned to tackle the problem. "No, no, no, you don't need a cable puller. Just do it by hand, and then use your barrel adjuster. We never use a cable puller except to pull zip-ties tight." When I mentioned that several fellow CB owners used the Yaw FD without chain rub, and said something about how the Yaw angle changes, both he and the other mechanic looked at me blankly. "That's what the trim function is for on your shifter. Just go to that first click to trim the derailleur when you get to the cogs where it's rubbing." Which tells me they have no experience with SRAM Yaw, and have set the FD up wrong from the start.

So I checked in with the owner of a new LBS a few miles down the road. They don't use or sell the cable puller either. "It's too easy to overtighten the cable. We just do it by hand and use the barrel adjuster." As we talked, he admitted that they sell only Shimano-equipped bikes, and neither he nor his current mechanic is at all familiar with SRAM. However, he's adding a young mechanic this week who supposedly does know how to adjust SRAM mechs. If I totally bungle this, at least I have a fallback option.

Off to Amazon...

It's been a while since I last went through the Yaw setup, so my memory is hazy, but I did it without a cable puller and came out with no chain rub (Silvio 2.0, 50/34 chainrings, 11-32 cassette).

None of the instructions (included SRAM instructions or recommended online videos) worked well for me.

As I recall, what I did was:

- Dial the barrel adjuster on the Silvio most of the way in (so it can be tightened later)
- Start with the lower limit adjustment dialed way in so that the derailleur is stuck in the upper chainring position (as shipped). Follow the procedure to position the derrailleur and set the upper limit screw, but do not hook up the cable.
- Dial the lower limit adjustment screw out until the derailleur is in the small chainring position. Then, pull the cable tight by hand (I use needle nose pliers) and hook it up to the derailleur.
- Continue to test gear combinations, adjusting the limit screws and barrell adjuster as you would with any derailleur.

I guess this is basically what Kline tried that left him with chain rub, but somehow it worked out for me. Maybe because we have different gears.

That in a nutshell is what I do. On the Silvio I have two barrel adjusters, one close to the brifters (so I can adjust while riding) and one close to the RD. This is one of the things I never understood why road shifter brifters do not have an adjustment at the shifters, like everything else. It was so nice to make those small fine tuning adjustments on the fly while riding. The thing I miss most about mtb'ing and bar end shifters. Otherwise I love brifters.

Two other fallback options:
1) I'll take a look at it. After all I'm now an expert since I've adjusted all of one
2) Quick trip to Minnesota to visit the Rubber Mallet Master.

Option 2 is your best bet

The Redding CA office has better weather; so that has to be factored in.

True dat. OTOH, I know where ReklinedRider lives, and it's a whole lot closer.

1) I'll take a look at it. After all I'm now an expert since I've adjusted all of one

Which is one more than I've done. Therefore, you're an expert--compared to me, at least.

Redding CA office is experiencing extreme heatwave over the next week...but better weather to follow!

Ok I'm going to quit get a van; and I'll just drive around the country from owner to owner to offer tune-ups from the back of my truck and then go ride with everyone. Think my PluckyBlond will let me?

 

[mzweili]

get a van

my latest acquisition allows me to go different places.
Just installed the bike rack this afternoon.
Even if it's at the end of the world, maybe one day I will show up in the Redding area.

Wow,, looks like you are preparing to migrate south in search of snow free roads and trails this winter.
If so ,,, all I can say is "Welcome snowbird"!
check out traillink so you can plan to visit the best? longest ?trails.
later,,, bye

Young Mechanic (Matt) really does know how to adjust SRAM Yaw derailleurs! The Silvio finally shifts properly for the first time in the year-plus I've had it. Up and down the entire 12-36 cassette with no chain rub on the FD while in the 50T Q-ring. No overshifts when moving to the big ring, no matter what cog I'm in. Woohoo!

Yay Matt! Good to know I too might now have a back-up. Which LBS is he with, if it's not top-secret?

Bike Crossing in Flowood. They closed the Baton Rouge store and moved the merchandise to Dogwood, behind the Hilton Garden Inn on Lakeland. Much smaller than the Ridgeland store. Matt says he saw a lot more SRAM and Campy down there, where it's almost exclusively Shimano up here.

 

[ReklinedRider]

Good to know, thanks! Shimano is great stuff but i LOVE my SRAM.

 

[super slim]

I have always been a three ring man, so Shimano is in my blood!!!

Good on ya, mate

I can barely adjust a double. A triple?? Nah.....

 

[Rick Youngblood]

I was too, until I got my Silvio and then Vendetta. Of course the 42t (granny cog) makes that possible for me. Maintenance on a double is so much better than triple...if I lived in reasonably flattish area, a single chainring would be wunderful ?

Now get one of those new 42T-10T SRAMs and you can got 34/50 or smaller on the nose and still go fast

My dream! And for SRAM to make an etap that supports those big cogs

That's where the in line adjuster is SOOOOO good!
