Thanks for all the replies folks. A lot of great info and ideas.
I’m building the bike for a guy who’s keen amateur rider and an amazing athlete. He’s transformed himself into an accomplished cyclist/time triallist over the last few years and the hobby has become an obsession.
He rides sportives and finishes at the front and also won his local time trial handicap league in his first year so he’s pretty handy – as well as being very good on an MTB.
He knows that spending £20k or whatever won’t make him any quicker but he just likes a bit of style and has more cash than he ever needs so enjoys spending it on cycling. (He already has four Cervelos).
He decided to do an Ironman last year so installed an endless pool in his house so he could swim a mile before breakfast every day. That’s his level of commitment.
Anyway, I’ll sift through all the info. Thanks.
Bruce – I like your ideas btw.
Oh, I know this is an MTB forum but you always get a more enjoyable stream of answers/abuse on here 😆
Beej/SBrock – Yeah I do operate on a tight budget personally but people I build bikes for usually don’t. (Except for the Hardrock guy!).
