Three Speed with Rear Derailleur
Hey, a quick question I was wondering about.
I have an old road bike which I ride as a single speed right now, but have been adding racks for commuting and was wondering if I could make it to a three speed..but not the internal hub way.
Say I were to get a rear derailleur and this freewheel..could it work? Giving me just a litttle bit more gearing options? This would be the perfect commuting option for me I feel...
Also as far as shifters go... it has downtube shifters..could I work those in, or would it be best to just get a bar mounted shifter?

Why not this instead of a freewheel/derailleur?

You might as well use the downtube shifters. Hopefully they are friction or they are indexed with a friction mode. If the latter, you might get lucky and the indexing works with the 3 speed freewheel.
You would have to adjust the derailleur stops for the 3 speed freewheel. There is a possibility that they can't be adjusted that narrow. A 5 speed freewheel is more likely to work and it is probably cheaper than that esoteric 3 speed. The 3 speed is cool though.
Neat looking bike.

Just go for it. Friction downtube shifters are OK with any rear mech. Just make sure your frame has the proper hanger. If it does not have a hanger then you must find axle mount rear mech. And don't forget to change the chain with a longer one. (do not add links to a used chain, get a new one - or old one that have enough links from the start)

Thanks all.
I really like the idea of a three speed, and I dont want to go internal as this is the beater/grocery getter/ sees every condition/stays outside/ I dont want to put a lot if money into it bike.
Is there any reason why this 5 speed from Shimano wouldn't work?
SHIMANO SIS RD-TY15 Bike Rear Derailleur 5Spd 5 Speed Medium Cage
Paired with that 3 speed cassette and my down tube shifters (which are indexed for a 5 or 6 speed....that may be the problem?- I checked this morning)?

I'D find the freewheel remover that fits on that , first..
or you have to destroy it to take it off, again..
if you cannot find it, don't screw it on..
+1 on a AW3 .. spare parts are there.. all of them.

Exposure to the elements is the strongest reason *FOR* getting an internally geared hub! The mechanism is sheltered inside, away from the elements. The Sturmey-Archer 3-speed hub on my commuter bike is over 50 years old and still going strong. Used "AW" hubs are strong, dependable, abundant, and inexpensive.

That Shimano derailleur should be fine. Some of those are designed for a bike without a derailleur hanger and horizontal dropouts, you don't want one of those.
Can you give us a link to that 3 speed freewheel?

Eh good point on that - I didnt look super close at it.
So a wheel built up with the SA hub is about $200 - too rich for my blood.

As said seek out used AW3's, or just stick with the single speed Freewheel.
[that uses a F/W remover that is commonly available.. ]
seen some single speed F/W with no removal notch ,OEM picked for Trikes.
you put those on a piece that keyway fits on the axle, presumably then you buy
that too, if you wanted something different, tooth count wise..

This was all just a thought - not ready to put the money in. But I will keep an eye out now for used AW3

I built my own 3-speed wheel using an AW hub from ebay, a salvaged rim (from another wheel) and new spokes. In all I think it cost me less than £30 to put together. It really is a better option than a 3-speed derailleur.

Some rear derailleurs don't have enough adjustment in the limit screws to get your range of motion that narrow. I had this problem even using a rear derailleur that was designed for 7 speeds with a 5 speed freewheel. On the other hand, I also once had a bike with a 9 speed derailleur running a 5 speed freewheel no problem.
