The Field of Dreams
it all looks "gay" to the outside world whether its a scooter, bmx, skateboard or mountain bike just "push bikes",no matter how obsessed some of us become about our bike riding, and the bikes....

Ask Pinkbike: Rim Width, Angle Headsets, and Carbon Cranks
I've seen a good number of broken SRAM XO CF cranksets, usually the pedal boss ripped out or the end of the crank arm fractured from rock impact. Also seen a good number of bent aluminium alloy cranksets from Shimano, RF, SRAM / truvativ and other smaller brands, but very few that have failed completely - I've seen more broken cromoly steel cranks from Profile when I rode BMX for many years - seeing something skating across the floor of the skatepark and its a Profile race crank arm with pedal, the arm has sheared off at the axle boss where the weld has failed. Bending is a good safe mode of failure for the rider, a sudden failure can easily cause a broken ankle, broken leg or other serious injury if the rider is thrown off the bicycle at high speed. The CF cranks seem to be the ones with the catastophic failure, probably from previous impact damage compromising the CF structure. Alloy cranks seem to take a regular beating with little consequence. Of course, its wise to always inspect your equipment before riding. The tricky thing with CF is you cannot really determine what the previous impact did to the structure, unless you have access to NDT equipment which is beyond the cost and availability to most riders, let alone companies.

Ask Pinkbike: Rim Width, Angle Headsets, and Carbon Cranks
I've done 100's of warranty inspections for customers the past couple of years - for both carbon fibre and aluminium alloy components including frames, bars and cranks Most of the carbon fibre I have seen with 'catastrophic failure' has been involved in an impact way beyond a reasonable engineering scenario like riding square into a tree at 30mph, driving into a garage with bike on roof of automobile, or the cyclist being run over by an automobile on the highway. The carbon fibre I have seen with some mode of failure but not catastrophic (i.e. slowly propagating crack in frame) has been determined to be from issues with design/engineering (you see the same issue on repeated units of the same model), quality control during manufacturing (bad layup, issues with handling damage to cloth) or historical legacy (metallic elements moulded into carbon fibre i.e. BB shell causing galvanic corrosion over several seasons) I've seen a lot of broken CF and Aluminum alloy parts. I happily run a road bike and mountain bike both with CF frames, CF seatposts, CF bars. I would not use CF crankset because there seems to be no real advantage, and a huge cost penalty. Several years back, Shimano (easily the leading producer of cranksets) brought a CF "Dura Ace" road crankset to market. Then withdrew the crankset as there was no advantage over their duraluminium model, a big cost penalty and rumours had surfaced of failures with the CF crank.

Doing it Our Way: Trek Factory Visit
Good article and its always a good thing to see bike brands doing some domestic manufacturing However, the bulk of Trek's production both CF and Aluminium Alloy is built off-shore by Giant, and Giant are the leading composite manufacturing company in the World for bicycles, interesting to see how much "knowledge" Trek have provided Giant compared to what Giant have provided to Trek ;)

Riding FOX's RAD Suspension
Early 40s were crazy rigid really liked that fork for confidence during extreme freeride I was doing, but found it a little too rigid when doing tree roots off camber during the odd DH race I did on that fork. Found 32 boxxers a little more controllable on that same track
