Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Why do

Road cranks have 5 bolts and Mountain cranks only have 4?

Mountain bike chainrings aren't near as big as road chainrings and they don't need that 1 extra arm for stiffness.

older MTB cranks had 5. I'll play the cynic role - they changed so they could sell more parts to people who had to have the latest candy. Same as adding one more cog into the rear cassette every few years (Campy is going 11 sp in 2009!). The correct term is Planned
Obsolescence.

^^^^ I have heard a rumor that some of the more competitive cyclists out there prefer their components to be lighter and perform better. Apparently, they are willing to pay more for these 'features,' and companies are willing to fill this 'demand' in the 'marketplace.'

smaller chain rings don't need as many fingers for support as Smashy noted, plus they're lighter...
