~58cm do-it-all gravel/touring/road/CX frame; CdF, Arkose, Jamis Renegade, Salsa Vaya, etc.

I'm looking for a frame to replace my road frame. Am a tiny bit over 5'11", looking for something with about 58cm effective top tube, stack around 600mm (or a bit over), reach just under 400mm.

My list of ideal features goes as follows:

• Clearance for 622 x 40mm
  
• Cable disk brakes
  
• Some luggage on the front fork; at least two bottle cage mounts
  
• Full rear rack (some cheap/decent CX frames ruled out...)
  
• 3 cages on the frame
  
• Steel (I'm fine with something like an Arkose though)
  
• 135mm QR rear, and 100 x 15mm axle front - so I can swap wheels with my 29er
  
• Sliding dropouts if possible, so I can shorten the wheelbase/chainstay length for road days, or go SS
  
• Combo of "sporty" carbon fork and sturdy full-rack steel (or similar) fork available, ideally easy to swap the two, cheap-ish
  
  

Obviously I don't expect to get all of these features.

Example frames that fulfil many of my criteria :

• Sonder Camino Al
  
• Pinnacle Arkose
  
• Octane One KODE
  
• Jamis Renegade
  
• Surly Straggler
  
• Soma Wolverine
  
• Soma Double Cross Disk
  
• Genesis CdF
  
• Genesis Vagabond
  
• All-city Macho Man
  
• All-city Space Horse Disk
  
• Light Blue Darwin
  
• Salsa Marrakesh
  
• Salsa Vaya
  
  

If it's a full bike I will probably swap the groupset for my 2x10 SRAM Rival/Apex groupset that I have already. So bikes with cable disk calipers are preferred.

Budget-wise I'm looking around £500 for a full (used) bike; could maybe go a bit higher for something fairly new; less than £500 for just a frameset.

I'm in Edinburgh but visit Durham, other parts of Scotland often and could also get to Birmingham on a weekend. If it's not near any of those places (or on the way from one to another) I'd need postage.

Feel free to crush my dreams and tell me I'm deluded
