I was over with Mark on Tue getting the bike serviced along with a few other jobs and saw the transplant job up close - very interesting indeed.
Can I say he did a top job on my bike and really went out of his way to resolve a particularly stubborn broken spoke end which I hadn't been able to remove. First class! It's great that he's OK with you seeing what's going on with the bike compared to it disappearing behind closed doors. Nice spin on the courtesy bike too. Ta.
