Single speed MTB but with gears...

If you do ‘conventional’ dinglespeed you get a forever-straight chain. And you can use a tough chain, singlespeed rings and cogs. Stainless steel stuff even. It’s goofy having a little fiddle with the qr at the trailhead but the bike is easy to clean and difficult to break. And zombie proof. I like it.

I’ve never done it with vertical dropouts though.

Looks like a reet barrel o’ laffs.

Just needs some smoked salmon wrapped round the grips and scrambled egg instead of sealant.

Breakfast pasty ideas gratefully recieved.

@cake any chance you had a rummage for that two speed FW?

Argh! What did you do to my Killer V!?

Kona forks! You heathen

@Skülly I have not but thank you for reminding me. Hopefully will be at my house next week.

Lol. Lockdown boredom twisting me melon, man

boom you beautiful man

Ah, @picco’s bikes are nearly as shittily conceived as mine. So that was yours huh? Cool name ‘Killer V’- in the great tradition of bikes with Boy Words. In the words of the philosopher Sting, ‘If you love that old bike but can’t find the room for it, set them free’

My bikes are easily as Shittily as yours, if not more, and I have way more shit bikes than you too.

Nah nah nah nah nah

Well I’ve built a two speed. It’s fun! Sort of either one or the other. Up/Down, Road/Offroad.

Second hand middleburn double, in fairly minty nick. Worn out but fine topswing XTR FD picked up from the seller of the frame. Single ancient Deore thumb shifter, got the other one ready to fit to the New Success RD.

Obvs pointless having a RD on with the single (I’ve added a huge limiter screw to keep it in place), I could have left the surly tensioner. Thought I’d fit it ready for a double FW. Then found out I missed the one I want at Bikemonger by a few days ... gahhh ... I did ask them to save it but hey ho, snooze=lose. @cake I’m now begging for your one!

Might need another link in that chain really.

nice that

Very good daft project

Would be interesting to see how extreme you could make a rear derailleur when it only needs to move one cog and take up a minimal difference in cog size

I'm baffled.

If you shift the FD does it force the RD to move as well?

Would love to see more pics.

I can't figure out of this is a joke or not.

Only one cog on the freewheel, trying to obtain a double, ie 2x1 at the mo, 2x2 intended.

Rear mechs do two things, ie the bottom pulley moves forward when I shift to the big ring. L-R movement will be triggered by a right shifter.

Ah OK. So you'll eventually have two shifters. Now it makes sense.

I’d be surprised if it did at all and absolutely shocked if it did it well.

It’s fine. Works nicely. As smooth as any friction shifting with non-angled teeth and non-ramped cogs, that is. It’s actually quite a joy.

Only prob is I keep overshifting down into the spokes, keep scratching the black ano behind the fw (I hate black parts, here’s a good reason why), as I can’t make the limiters limt enough on this particular mech (even with extra long limiter screw, reason is the bit of metal stopper that meets the screw is really short, the long screw clears it now).

I think 16/19 would give me a bigger ‘difference’ in the pedal resistance as I shift down, I’m not really noticing that I’ve done the shift (slowing down as I shift) and carrying on moving the shifter past the cog. Bleurgh.

Using @cake ’s DOS (thanks buddy!) that’s 17/19, so I’m getting these ratios, not quite as even spread as 16/19 would give but it seems good.

Schooled. Glad it’s working out.

Could you set it up so that in the top cog was the max throw off the shifter then only rely on the limit screw to stop you coming off the bottom of the fw?

That’s exactly what I’ve been trying to achieve, yes. Unfortunately Deore thumb shifter has this weird lever thing (for switching between 7sp index and friction) that gets pushed out of friction mode when you push the lever right out (max cable pull). It sort of means that the ‘end’ of the pull does something I don’t want it to do instead of just stopping.

Aha, typing that out has made me realise: instead of worrying about the mech, maybe I need to change the shifter!

Schooled. Glad it’s working out.

Thanks btw! it’s tons o funs

Still haven’t worked out if this comment was drug-induced or what

The very first 700c I ever bought was set up like this, 52,42 + 18. Was actually loads of fun to ride.

Maybe a Sturmey, friction only thumb shifter?
