I'm building a new bike (Cervelo Soloist) and I'm about to buy a Groupset (very likely Ultegra SL).
My current bike a 2001 Klein Quantum (this will become my spare bike) which I've been riding for 8yrs runs 53/39 and 12/25.
Like the rest of us I'm not getting any younger (I'm mid 40's) don't have any issues with the hills where I live (the hills are short and shallow) and have on occasion wished I had a higher gear.
So should I buy another standard and stick with 12/25 and maybe buy a spare 11/23 or be sensible, give in to the biological clock and go for a compact with 12/23.
It will be used for pleasure and the odd triathlon.
