Bigass chainring?

I'm building up a recumbent and I'm trying to avoid using a jackshaft. Does anyone make a chainring in the 70 tooth range?

Come on wanders, he's trying to build up the fastest Mup rig so he can drop all of those silly roadies on their conventional bicycles.

OK then. It looks like you're going to have to fabricate it youself like this guy.





For what it's worth, "I just jackshafted a roadie" will get you more recumbent cool points.

LOL. Those teeth look like they'd wreak some havoc on a chain. But maybe the diameter mitigates that.

GO BACK to where you belong!!! We don't need your kind here, and that chainring looks like it won't be very effective with the shape of the "teeth"

Bent's are so much faster than wedgies, you'll all learn once you get droped on the Mup by one of them. 'Bent's can turn a fat, bearded granola-eating college professor into a pro bike racer.

That's why I stay off of the MUP's and on the road, where the climbs are.

They were all clogging up the Metro Parks Sat.
Bents with jingle bells,dog pulling a trike,professors,etc.
Was there a convention here or is the circus in town?

I always enjoy a visit from our recumbulator friends so I will lend a hand to Foster from Florida.
BIG chain ring for you:
Find an old Western Auto outboard.
Remove the flywheel from top of motor.
Voila,a 100+ tooth ring.
You are now the fastest mechanical beach chair in God,s Waiting Room.

I've yet to see a Bent in the parks, maybe you should stay off of the Mup?

And we hate bents because they're the Rush Limbaugh of cycling, without the oxycontin addiction.

I think the MDT rings are made by Highpath?

Paragon Machine works used to make some 60t chainrings. Maybe they could fabricate a 70t one for you.
