Yunki, thats Chris Jones, he races at Gawton and Tavistock woods when he is able to.
Top fella, bit of a surfer too, also in the process of developing a XC and DH hand cranked trikes.
The photo appears to be Tavistock woods, he is most looking forward to running larger wheels, over the 20″ wheeled rigid trike he is running now, he also knocked out a charity 26mile run over Dartmoor last year on it as well.
Was Lynx now changed to Merici ( i think, maybe spelt that wrong) oh and in that photo he is using the single brake (Magura HS33)as he has to take a hand off the crank/steering to grab the lever, also note below his left hand braking, is the gear shifter for the right hand.
This is not one of his bikes, he bought it, decided he could do better and has set about designing and doing his own thing, but the rigid steel framed 20″ is pretty Niche, he dosen’t have a beard 🙂
