Disk brake mounts on frame and fork

13.5 inches, having looked on the Trek site for Marlin 5. ( This is 7)

Quite a few places where the paint is worn,

the frame is sound with no dings. Wear on stays is shown,

probably  a chain jump at some past point.

Good classic model.

Included are the headset and stem, also the seat post with clamp.

Hanger for derailleur is included.

Shell threads are good. 

Forks are RockShox ( I had misnamed them) XC30

Will send by Parcelforce 48 hour  service.

If needing to take off fork to fit in the box, I shall.

i.e you may need to put the fork / headset back together if posted.

Local collection an option.
