well my commute is somewhat different. I get dressed ready for work but pack a rucksack with what I need plus my cycling clothes. Put on cycling shoes get on bike and ride for 40 seconds to the small harbour and catch a little ferry across the fjord. Get off and cycle 600m to office. Have shoes in my office. At end of day change in to cycle gear and pack office clothes in to rucksack and cycle the 30km round the fjord back home. 50 % off road.
its been there since i built up the bike about 6 years ago and works grand. the big ring is for pottling to the local trails and the mid and granny for the actual trail riding
ive got an old 853 battleship grey BFe and its brilliant. I bought it instead of a soul at the time to be my hard as nails trail bike. 5 or 6 years later and its still my main trail bike. Cant fault it for the style of riding round here
