    Single Speed Front Sprocket Five Speed Cassete in the Rear

    hello i was wondering if it is ok to put one gear on the front crank and use a five gear cassette in the back. the shopkeeper at my LBS said it wasn't a good idea. is this true?

    I don't really see a problem with it. Dunno if the front der. would be needed to keep the chain from jumping off.

    Sure, that's what the old 5 speeds of the 70's & 80's were. I don't where you'd find a new 5 speed
    cluster today tho?????

    Oh yes, don't forget that you'll need a shifter and derailer that work with 5's.
    My preferred bicycle brand is.......WORKSMAN CYCLES
    I dislike clipless pedals on any city bike since I feel they are unsafe.

    thanks for your help

    I use 5 speed Shimano freewheels on my commuter bike. I've bought them in the recent past for about $15 over the web. They're hardly extinct!

    I believe Giant makes a 7 speed with a single gear in the front. SO I don’t know why 5 wouldn’t work. Not sure if that is enough gears for me.

    No reason it wouldn't work.
    IF uoi have friction shifters, you could probably stivk a 6-7 speed on the back and have a little closer steps between gears. I hate that big jump between 4-5!

    If you notice the bike I ride you will see it has one sprocket at the crank, a three-speed rear hub and a seven-speed cassette giving me 21 gears. You could easily have a 5,7, or a new 8 speed with only one sprocket in the front. It would be easier or at least as easy to find a cassette with seven gears and two extra wouldn’t hurt. IMHO

    I think you need a new bike shop, or at least an explanation of why that's a bad idea. I have an old Trek that started life as a triple-crank tourer, then did five years or so as a five-speed around town (I took off all but the middle chainring), and now is a singlespeed. Unless there's something really unusual about the setup you plan to use, I can't think of a possible problem.
    If you don't have a shifter for the rear, you don't need a five-speed index shift lever. Any old thumb shifter or friction lever or barcon will work.
