is reverse 1x8 or 9 possible?

[FyrFytrRyn]

i often see (and have ran) the single gear up front and a full cassette in the rear. has any one ran 2 or three gears up front, and a single in the rear?

I have never seen this but you have a few options. You can get a flip flop rear hub and have a single speed cog on either side of the wheel. Remove it, flip it, install it. I've also have seen dual cogs so all you have to do is move the chain one over. These configs probably won't work with chain tensioners but some do get lucky in regards to chain length and slack.

I thought about doing that for my commuter. The only concern I have is with your chainline. If you run a double or triple up front, your chainline could potentially be off enough to cause your chain to jump off your cog. I guess you could run a chainguide in the rear. Maybe that would solve it.

When I ran a 1x9 for mountain biking, I had to use a bash guard and chain guide to keep the same thing from happening to my single chainring up front

I believe JamR has one of his bikes set up as a 3x1. You would still need to run some sort of tensioner or derailleur in the rear to keep the chain tensioned.

MTBMaven had, or has, a bike set up 2 front one rear. Bailout gear on a Singlespeed.

No one does it beacuse the front derailleur is notorious for not shifting when you need it to. With a 3X1 you have to keep a functioning front derailleur and shifter AND a rear derailleur to take up the huge chain slack between the front gears. With a 1x9, you end up losing about the same amount of weight have 9 gears instead of 3 with better shifting. Maybe if you can replace the RD with a YESS tensioner made for FS frames, you might save mpre weght and have a cleaner look, but your chainrings better be pretty close in gear spacing.

Soon to be seen at an STR event... a 2 x 1 Tandem Cyclocrosser!!

Why oh why? you ask... because we can!

I think JamR setup a bike like that with some good success. Maybe try to PM him?

[Rockinthecasbah]

its called a dingle setup and it only works well if you have the surly type tensoner in the back or something like it.You could cut down a regualar cassette and space it out to only 3 gears and save alot of weight and have it shift better. if you need help cutting down a cassette post up i usally run a 3 speed on my 4x bike

I have a 2 speed that I run with 2 chainrings and a single cog in the rear. I run a front derailleur with a grip shifter and a Paul's Melvin in the rear to take up the chain slack. This set-up works fine for me.

Rockin, you must be one good rider. My dingle speed sucks.

the real question is... have you upgraded to a dingleberry speed?
