Do they have disk mounts? Mmm? Difficult to tell from the pics on the website. there is something back there. No mount of the fork though 🙁

Also, do 5'10" chaps really ride the size L – I ride a 56cm normally and I'm pretty long in the leg for a chap of my height. I feel a touch cramped on a 55cm frame without a stoopid long stem.

What other cheapy CX frames are there kicking about?

yes, they do, as shown on the second pic across the top row on this page:-

something liek this would give you the disc mount fork:-

i seem to remember planet x doing an alloy cross fork with disc mounts

Ah-ha!

I didn't actually open that picture … 😳

Planet X alloy fork seems no longer availible. Cheers for the suggestion.
