Lets have a look at my latest bike. My Intense Primer I've built for everyday trail riding. I got the frame out of Defcon Cycles here in Australia and have built it up with a variety of parts from my old Canfield Riot and new parts specifically for the build. The goal was a relatively lightweight trail bike that wasn't going to compromise me when the going gets tough.
As most of my rides are less than 30kms I've tried to follow the 'pack-less' philosophy. Quick link taped to the front brake line. Samurai Tyre plug kit in each bar end and a Backcountry Rapid strap that holds a tube, 2x CO2 cannisters and a couple of tyre levers. All I've got to bring with me is a multitool in my pocket. I'll be looking at eventually migrating the multitool to the bike somewhere.
Both the Raceface Next SL cranks and Shimano XTR pedals have been with me for many years now. Both still going strong. The pedals have been serviced a few times in that time period.
The bike as it sits, weighs 12.7kg with pedals. I'm really happy with the way its riding, both up and down. The only planned mods is to possibly bling it up a bit with some titanium and aluminum bolts. The setup will change with the seasons and depending on where I'm going to be riding. Mostly just tyre swaps so I'm not caught out.
