You change gears by swapping the front and rear wheels. ---

Mostly finished up the 8yo’s new bike (need to get some different grips) It was pretty fun as both kids helped put it all together. ![IMG_8229](https://cdn.tarck.cc/original/3X/7/1/71f5522b73e59e468612cba0a0f9da11fe4bb05c.jpeg) ---

shift with a stick (to hold up the rest of the bike while you remove and swap the wheels) ---

Remember when people were running two cogs and two chainrings for four ultra-manual gear ratios? Anything to not use a derder and continue to impress your aging single speeds pals. ---

Yea I do and I considered it. I’ve run two different freewheels or cogs on rim brake bikes with flip flop hubs and kept a 15mm in my fanny pack. But now I’m going back to disc brakes and can no longer flip flop to avoid using a derailleur and shifter. ---

Sounds like it’s derder and shifter time 4 u. I have some if you can’t find any to buy. ---

Wait why can’t you just put two cogs on a disc wheel and split the chain line? I’m sure you can get it close enough. ---

But now I’m going back to disc brakes and can no longer flip flop to avoid using a derailleur and shifter. I have/do run double cogs and chainrings on my SS mtb so that I can choose between two distinct gearings with perfect chainline (34/19 and 32/21) by dropping the rear wheel without adjusting chain or stay length. I don’t change during rides, but it saves a fair chunk of time stuffing around with chain whips etc in between rides on varying terrain. Definitely doesn’t look as nice as 1x1 though ---

I left the cassette side cogs on as a flip-flop bail out in case I really hated fixie mode, but didn’t end up bothering with it Milk crate basket strapped to the handlebars/fork crown was rock solid and rode really well over bumpy 4wd tracks as sprung mass with 160mm of squish working below ---

Despite pears’s hateration in this dancerie, 2x2 (as pictured on my Jones) works really well and is easy to change quickly. You’re worth it. ---

> [@Face](#): > > I’ve been trying to figure out how I can have a disc brake single speed with two possible gear ratios. Not gonna run a 135 spaced fork to do it tho, we’ll not yet anyways. Run a dingle speed. Just match the total teeth count on both combos. Or within a couple of teeth. I’ve done a couple. Easy as. My current one has gone back to a 3x1 tho with a locked out dangler and toe/finger change on the front. ---
