right so i have a felt55 with a 53/39 ultegra chainset. just moved to very mountainous region with massive hills and virtually no flats. went for a few rides and definitely could do with a few lighter gears. so i just bought a 105 compact chainset. The only problems is i will have to change the chainset all by myself. i am technically inclined and don't mind doing it but am quite inexperienced - my questions are:
- do i need any special tools?
- is there any step-by-step guide somewhere maybe with pictures that i can follow?
- any advice, tips, tricks, stuff i should be aware of?
