Hello! So... quite probably not the most unique build you'll see around here, what with the recent On One deal, but my first step back into the world of MTBs for almost a decade and I'm super excited to be back on some knobbly tires.
I have been buying a mix of second hand/bargain bits and have a few questions about the compatibility and some potential options for the brick walls I seem to have hit:
1. That 'clearance' for the chainring (32t) and crank arm looks a little err... tight?! Is that just me or do I need some spacers in the BB?

2. Brakes/Shifter. I'm wondering what the best way of mounting my new 11spd XT shifter is. It's an I-Spec B type mount and the brakes are an older XT model. Now, maybe I just need to suck it up and by a bar-type clamp shifter, fine, but I'm wondering if there's a way to get this one working as it looks strangely close to fitting or like it should. Somehow. Maybe the pictures below can explain better than I can:

As you can see there's a 'hole' in the brake lever (it's not threaded) which seems to line up perfectly with the shifter when placed on (what looks to be) a 'track' for it. Surely this is meant to work? It's a perfect fit. I've tried fitting a bolt through from the shifter side into the back of the bar clamp thread and then using a second bold for the normal bar clamp closure, however it doesn't appear this thread is long enough to accommodate two bolts.
Any ideas on this? Hacks/bodges most welcome!
Look forward to sharing a full build once the 254th Hermes delivery has been made...
Thanks
Search Scandal, there are two threads running with lots of info!
1x driveside spacer on mine (shimano FWIW)
No idea about i-spec, other than I've heard there are about 3 different versions of it
at a guess you need a boost crankset too? I bought one but not fitted yet. I also bought a 34t oval ring which.... might have been a mistake....
Type in google (I-spec b clamp) then click on bikeradar site 👍
Needs boost chain set and yes 34t ring fouls 🙁 I tried. You Could bodge with more spacers driveside I guess but it will mess up Chainline.
Excuse to buy some newer brakes the ispec b is neat 🙂
There should have been a bolt that goes through from the shifter into the brake mount. It uses a square edged nut that sits in a groove in the brake mount, you have to mount the shifter to the brake then the brake to the bar.
