Re: End to End Build
Was at a loose end yesterday afternoon so spent an hour doing a first draft on the gears.
First issue was the chain... This is a dedicated touring frame so the chainstays are really long... Started with a 114 link chain which didn't quite meet using the big/big +2 method and was obviously out.
Out came a 116 chain which just made it. I may try to find a 118 for actual riding as the rear mech is a long cage and combined with the clutch will take care of a couple of extra links with ease so I shouldn't need to worry about chain slap. The 116 can stay on just now though.
The front mech was cabled and up and running after a couple of minutes, requiring only a tiny adjustment of the limit screws as I had done the height and alignment when it was fitted.
The rear mech took a bit more effort... There's no cable adjuster on the X0 rear derailleur, so I used a Campag inline adjuster to work with the barrel adjuster on the frame stops. A couple of trims to outer were needed until I was happy. At the other end it took about 6 trims of the outer before I was happy... And I'm still not 100%... As you can see from the pic below it's got a fairly steep curve in it.
The reason for this is the cable entry angle on the mech... I'm not used to mountain bike kit, so maybe this is normal, but I've never ever trimmed so much off a rear mech cable outer. Once it was cabled though, it took less than 5 minutes to get it indexed across all gears.
This time round, I'm using alloy-levered Centaur ergos with the SRAM rear mech and the shifting in the workstand is absolutely flawless. Once the limit screws were set and the tension dialled in it clicked up and down as if it was made to rather than a hybrid of two manufacturers.
Unfortunately, it wasn't all perfect... The right hand shifter lost its grip on the index ring causing the downshift lever to move without shifting. I'll need to strip and rebuild the shifter with new g-springs and carrier.
It's chucking it down here today so it'll be tomorrow at the earliest until the grand TAH-DA! Photoshoot.
