Re: [RBW] Appaloosa 1x9 issue/question
Fantastic! That chain arm looks like a much better position in the big cog. Yowza, that’s a big cog. Grin.

Re: [RBW] Appaloosa 1x9 issue/question
I run the exact cassette you have with a Shimano XT M772 rear derailleur and it works reasonably well. I think the derailleur you're using might not have clearance for a 40t ( i know on paper it doesn't but in rear world they can work). The M772 technically doesn't either but it does clear. If that's what you've been offered up I'd recommend trying it. The 772 hangs a bit lower with it's longer bracket. On Sunday, December 9, 2018 at 7:48:16 AM UTC-8, William R. wrote: > > Ok.

Re: [RBW] Appaloosa 1x9 issue/question
Another thought, one which doesn’t offer any specific answers but is a general principle I came to in my drivetrain quest: the drivetrain takes constant pressure and even more on climbs and even more shifting while climbing. It’s well worth getting a system that isn’t jury rigged to function, but instead is being used as it was intended, if that makes sense.

To be clear, this device simply lowers the derailleurs attachment point to the bike? Does the Shimano Shadow type derailleur do this as well or does this Wolf Tooth component do it better by lowering the attachment point even more? The Road Link is intended to extend the range of a derailleur not meant or designed for such large sprockets, by lowering the attachment point. Basically, it extends the length of the derailleur hanger. Think of it as a drop-bolt for a road-type rear derailleur. According to WolfTooth documentation, the RoadLink is not intended for use on the most recent MTB rear derailleurs: WolfTooth has other products, "GoatLink and GoatLink 11 which are specifically designed for Shimano Shadow+ 10 speed rear derailleurs (clutch type ONLY) which have a Direct Mount link (including spacer, if so equipped) or B-pivot knuckle with a thickness of 7.9-8.1mm. Shimano changed to this sometime in 2013. Very early Shadow+ rear derailleurs have a thinner link and are not compatible." [from WolfTooth web site] If the question is, how do the MTB type derailleurs designed for huge sprockets do it, that I can't say. Likewise, I can't say if a Shadow rear derailleur can handle a 40T rear sprocket. That's well beyond my knowledge base. I haven't personally used a RoadLink either, but I have read a good deal about them on the Paceline & VSalon forums, where they are well regarded, with many happy satisfied users.

Re: [RBW] Appaloosa 1x9 issue/question
Yep, the RoadLink just lowers the derailleur so it is further from the cog. It works great for some, others have reported that it works but shifting to the largest cog isn't as smooth as it could be. If you are considering a new derailleur, get one that officially supports larger cogs. These derailleurs are designed for 1x setups, so as a bonus they will typically have a clutch as well (which will help make it harder to drop your chain). Not all Shadow type derailleurs support larger cogs, and generally long cage derailleurs do not (but you are running 1x so no need for a long cage anyway). I don't know of any 9 speed mech that officially supports large cogs, and I know of exactly one 10 speed mech: https://bike.shimano.com/en-EU/product/component/deore-m6000/RD-M6000-GS.html Note that the long cage (SGS) version of this derailleur does *not* support larger cogs. Only the GS version got the new large-cog-frienly cage design. William On Sunday, December 9, 2018 at 9:50:46 AM UTC-8, William R. wrote: > > Option "4.)"! Thanks Steve.

Re: [RBW] Appaloosa 1x9 issue/question
Steve’s idea looks good, Bill. Also, I learned the hard way to only use quicklinks when extending a chain, never a chain tool. With narrow chains (7-8 speed and above) it’s just too hard to get the pin back in correctly. Of course, triple check the quicklink to ensure it is fully clicked into place.

Wolf Tooth Road Link /The RoadLink™ derailleur hanger extension is a unique patented device that offsets the position of your road derailleur to make it possible to run a wide-range mountain bike style cassette. It is an ideal solution for riders looking to convert their road, gravel, cyclocross, or commuter drivetrain bike to attain the simplicity and reduced weight of a single front chainring but without giving up the gear range of a double. It is also great for riders with double chainring bikes that want lower gearing for those ultra steep climbs. It does not compromise the shifting in the smaller cogs of the cassette but yet it enables the derailleur to work with as large as a 40T cassette. -- https://www.wolftoothcomponents.com/collections/derailleur-optimization/products/roadlink / RoadLink -- Steve Palincsar Alexandria, Virginia USA -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

Re: [RBW] Appaloosa 1x9 issue/question
Good advice Patrick! I did consider going down to a 36t chainring. And if this new cassette is less than hoped I may yet. Or like you say, go back to the way I had it in the first place and just LCG it when pedaling is no longer optimal! Now that I consider it, I’m beginning to wonder what I was thinking. Oh well, as long as it’s on and all set up, I might as well try it and see how it goes ;-).

Re: [RBW] Appaloosa 1x9 issue/question
Alternatives to the excellent advice already given: — keep the old cassette (or get one that goes to 36) and switch to a 36 chainring. How much do you use the 11t? Test it by riding one gear up (lower gearing) on the downhills and see how you do. You’ll max out and coast a bit sooner is all. — keep the entire old setup and walk a bit more often as you get stronger in that low gear.
