Thank you!
I am glowing with achievement today, despite the bike not leaving the garage. I phoned the LBS to ask about the shifter and the pedals. He talked me through how to move the shifter to get a better angle, and suggested that I try swapping the pedals between bikes if I prefer the Marin pedals. I'd wondered about that but wasn't sure about asking in case it would invalidate the warranty. He said he'd be more than happy to do it, but talked me through how to do it so that I wouldn't need to drive the bike in. So I have swapped pedals between my bikes, adjusted the shifter position and also removed the bell for good measure (calling out to people seems to work better). Next task is to learn how to change a tube. Now that I have two bikes I can do the learning things on the Marin without taking the Spesh out of use.

I just have to ask Mr Hebe to check that the pedals are on as tight as possible, then I'll get out on the bike again on Friday and check my work! I'm still a little sore from yesterday's ride to take it out again today.
