Prepping for the TDPS, & the first 15 - 20 mile part of the ride is up hill.
Sirrus carbon elite disc.
These old legs needed a little help on the hills. Sirrus had 9 speed 11-30
I put a used 11-34 on the Sirrus to try it for fit.
Maxed out the deraileur when on 34 & 34 going to 50 on the crank.
Yea... DON"T DO THAT, but have yet to stop shifting until the shifter stops working.
Researched chain length, was 112 link , math formula says I need 114 link.
ordered a KMS x9SL (116 link) (& a park chain tool)
popped off 2 links & it fit & shifts OK.
even though I'm 2 teeth over the RDR 32 teeth max. (Medium cage Shimano Sora)
Have a new cassette (11-34) on the way, old one using for testing had 1200 miles on it
off the skye mtb which now has a 11-30 off the sirrus) .
If I could've gone to a 36, I would've.
Don't want to give up the 50 - 11 down hill speed so don't want to change the crank.
(Unless down from the 34 to a 32 or 30, which gets into the derailuer
not keep the chain tight on the Low/Low gear. (& not sure what happens on the front derailleur)
Now 4 tubes (2 for spares in the saddle bag) & slime & another water bottle holder
new pedals (Shimanop A320s) multi tool , chain links, pump patch kit.
+ box up the bike & oversize airline baggage fee
New to cycling, ( less than a year)
(What I've learned in less than a year, bikes are black holes to throw money into ) LOL
