Ever seen a chainring this big?

[Globalti]

I have just stumbled upon this picture of a bike somebody lent me in South Africa. The big ring was something like a 62 if I recall. The FD wouldn't change down to the small ring, which was something like a 36 so the very hilly ride I did was absolutely exhausting as I ended up climbing everything in the middle ring, a 50!

It went fast down hills though!

Bonkers, eh?

Looks like Halfords fitted the forks.

Guy Martin used a dual chainring system for his British record a few years back.

Neither are huge but combined the real wheel is quoted to be rotating at 1,460rpm for Guy's 97rpm cadence. Bonkers

And less chance of grounding out on speed humps than the ones upthread

That (and the small front wheel) will be so that he could ride closer to the car he was drafting.

Cantis! I guess because the frame was selected for BB height.

... then I read the article "I use a Trek carbon frame bike, and a Trek ION aluminium bike (cyclocross frame) that has wider front forks so you can unclip the brakes and keep going if you break a spoke"

That could almost be classed as a trike.

I think when turning right at speed it would be.

Pah! That's nothing, I ride a 100-50 chainset around the Welsh Valleys. I was also the second man on the moon and own a private jet.
