I have a 2005 modifieded canondale jekyll I have spent about 1200 upgrading it ( i ended up riding more than i thought 80 miles a week) Is upgrading the crank a worthy upgrade so far I have upgraded the cables, fork, brake lever, tires, chain and rear derailer. Would this be a good next up grade ? I was thinking a Truvativ Holzfeller since i ride pretty hard and do some drops up to 7 feet. Im light about 125 pounds so I am able to get away with out braking many things due to weight. What are some good bottem bracket choices? for around for up to $100?
