one by eleven

While I have original flavor SRAM Red on my road bike now, I am mainly a Shimano guy.  XT is my "Go To" on a mountain bike, I have used 105 on a road bike and drool over DI2 for either.  Even so I covet that SRAM 10 to 42 tooth cog.  My 9 speed is getting a little long in the tooth sic, the last chain I put on had to be "Ridden in" some before all the gears worked.  I recently tried to repeat this feat and she was just not having it.  Well it has been two years (I have ridden my single speed and road bike a fair amount of that time).  I have ridden my 9 speed straight through the existence of 10 speed.  The last chain that rode in was around when XTR released 11 speed and SRAM was introducing a second level, all boo koo bucks.  Fast forward to today,,, Finally durable, affordable, raceable XT was came along and now that I need it, it is high demand of course.

I am concerned that 32/42 will not be low enough in the the long High mountains of Durango,  I have been practicing using a similar low gear, which showed promise.  On the flip side I am wondering if I will miss that high gear inch that the 42/11 rolled out.  I am from the old school when the standard CR was 48-38-28 with at 12-28 6 speed cassette, but I never road that in the actual mountains.

I finally sourced all the parts, but had to get an XTR shifter, due to availability.  I hope the pretty carbon parts hold up to my abuse.  First ride tomorrow, here are some pics of the parts old and new.

Out with the Old

In with the New and Uncluttered
Trio of Shimano goodies
Add in the Ablolute Black Oval Chain Ring
Shifter
Derailleur, Good in a clutch!
Big as my 160 brake rotor
The Oval Office
Hope it makes up for that low gear I will not have
All Shiny and ready to Rock


Doing this on the cheap meant using my perfectly good old 104 BCD XT 175mm crank.
I am running a SRAM 1190 chain, until it wares out, then will probably switch to KMC as they seem to take for ever to stretch out.

Dialed in the chain length and B tension and everything seems ready for a real world test.

I like the threaded chain ring bosses on the Absolute Black, time will tell if it holds up.  But I got to go back to steel bolts.  I used the long ones from the old granny ring.  I was using aluminum CR bolts and nuts so I could use an Allen wrench on both sides.  Mute point now.

The Derailleur cage is stiff with that clutch on, I have been drooling over that since I got my 9 speed shadow derailleur just before the clutch came out.  We will see if the clutch and the Narrow Wide CR actually keep the chain and reduce chain stay slap, on in the conditions that I ride in, rough and rigid.  That 11t is still really close to the chain stay.

I am so looking forward to not having a front derailleur.  I can not move up my rear wheel in the sliders and not drag rocks across a derailleur.  And of course you loose the weight, the shifting and the shifter. 

I took this opportunity to use a lock in to limit the inward movement of my grips.  Even wire tied they migrate in, I hope this solves this problem.  Lock ons are to thin in the cushion department and not work on my bars anyway.
