There is an isofix bracket for the mk2 Focus that looks identical to one I fitted to a Volvo S40. The one I got was a genuine Volvo part from a main dealer and it bolted into pre-existing holes designed for that purpose.
Not sure I would have felt safe using something off Amazon.

The 0C looks like a batch number or similar. It sounds like the picture is of the left-hand crank. I think the right would say FC-M7000-11 for non boost or FC-M7000-11-B for boost.

Bottom bracket is 118/73. If they did a longer axle I’ve not seen one. It’s marked 68 etype, 73 std no spacer.  I tried a 2.5mm spacer and whilst there’s more clearance, the nds cup has to screw in a long way to support the nds bearing. Everything should fit fine, chainring to centre is on spec. It’s just odd how the chainstay curves out towards the crank arm where it joins the cast yoke.

It’s a 32t boost. Centre of BB shell to centre chainring is 53mm.

The cranks in the photo are NX powerspline so no spacers or adjustment. Same crank to chainstay dimension as the GX/SX Dub cranks the full bikes come with. Gap measures 1mm. I can’t see them shipping bikes with clearances that tight but I’ll see what Planet X say tomorrow.

Anyone had a problem with the drive side crank almost touching the chainstay? I’ve tried boost and non boost, Shimano and SRAM and they’re all within 2mm. This is a boost NX crank.
