Right, it took a while in the end but finally have a 'bent build and ridable.
In the end it took almost 6 weeks for ParcelForce to sort themselves out and get the frame delivered. On the plus side it was in good condition and undamaged when it did finally get delivered. On the down side it was the wrong colour! At some point there had been a mix up at Velomotions end and I got a white frame and not a yellow one as ordered. Rather than messing about returning it and getting mixed up with customs and ParcelForce again Igor agreed to refund me the cost of getting it resprayed here. That took another week or so but I'm really happy with the end result. There was nothing wrong with the quality of the original paintwork, it was just the wrong colour!
Assembly was a learning curve. I used my Audax bike as a donor for running gear, wheels etc. While it was mostly straight forward there were a couple of places were the tolerances on the frame were a fraction out but a combination of very careful dremmel work and sand paper got it sorted. I very nearly cut the donor fork steerer too short but caught the detail in the instructions from Igor just in time.
I experimented with thumb shifters but just couldn't get a good setup with them on the superman bars so plumped for bar end shifters in the end. The MTB specific shifters from Microshift aren't cheap but they are really well made and work perfectly with the Deore XT rear mech from the donor bike (It had very silly gearing with an 11-50 cassette).
I started out with SPD pedals but very quickly switched to flats after flailing madly trying to get my feet in them and weaving like a drunk puppy all over the road on my first couple of tries at riding it. Flats have worked out really well and I'll be sticking with them I think. I'm still working on final details like where to mount the Garmin, lights, mudguard position etc. Debating making the seat angle a bit lower, but that will mean I have to shorten the steerer tube to see over it, so it can wait for a bit I think. Started on the highest position but found that reducing it a couple of steps actually made it easier to ride.
I've clocked up around 50km on it so far with only one fall when I messed up a gear change on a steepish hill and lost my balance. Otherwise going well so far. My only real issue atm is slow moving traffic, I still need more practice at slow speed balance, anything under 5mph and it gets very iffy and pulling away in traffic is still a bit hit and miss. Doing 30 mins a day just practicing atm, with my longest ride being today, doing an hour mostly on quiet local lanes. Looking forward to being able to get out longer and further with an eye on getting back to Audax next year.
In the mean time here is a picture of the Flying Banana as my wife has dubbed it.
