Just got back after a quick blast around the block. First impressions:
Straight away there was a worrying rattle at the front end, it sounded like two skeletons shagging in a dustbin. Fortunately it turned out to be the casing on the front light, that'll have to go.
It took me a while to get used to the shifters having never used this type before. I'm finding it pretty tricky to change from the drop bars, although I do have hands like Donald Trump.
The gear change seems a little clunky to me so there may need to be an adjustment there (that's another night on YouTube!).
Also, a little advice: check how easy it is to disengage from your brand new SPD pedals before you actually pull up at a junction. That could've been embarrassing!
