I'm happy to report that ahead of the game this year as just returned from the shed and "in the dark with a headtorch" tinkering - adjusted saddle height, changed bars, set up rear brake, fitted bottle cage, removed barends (note: I set up the bike and test rode last Sunday and all was good. But prone to more tinkering than Claudio Ranieri. Good news is that I cannot change the cassette as there isn't one).
This presence of mind should mean I can try it all out before work tomorrow.
Ch-ch-ch-ch-check me out!
