Hi PH - Your adventures with the oil change make me glad I've decided to outsource that (for now, anyway). My local shop, where I got my Raven delivered, has a good relationship with SJSC and is going to be sorting out oil changes for the half dozen or so ones they've received on behalf of other Londoners.
I've only done about 1200 miles so far, but I'm really very pleased. It's just so comfortable over virtually any sort of terrain - I can't imagine another single bike that would do the same. Last Sunday, for example, I rode the length of the Great North Way (otherwise known as Sustrans route 12 in Hertfordshire), which included some really muddy offroad bits, well-paved B-roads, country lanes, and hard-packed gravel paths. Of course, I was happy over all of it, which is more than I could say for the unfortunate Dawes Galaxy rider I came across at one point!
I did manage to do one more Audax ride - a 110km summer ride just north of London. This one went much smoother, and I was pleased that there was a first-timer I could take under my wing! Hope to do more this year.
Andrew
