Is it 8 speed?

Bought a bike second hand and it has an 8 speed cassette but looking at the cassette it appears to be from a different cassette. ? The gaps look different. ? Any idea how to check if the sora flightdeck changers are 7.8.or 9 speed?

    Count the clicks and add one.

    That doesn't make sense.

    For the levers, if you fold back the rubber hoods you should find a model number, e.g. ST-3200, ST-3300 etc. Google it and find out what you have. (or disconnect the cable and count the clicks...)

    Sorry about making sence.. the cassette is made of a large block of six gears plus 2 individual single gears... the two don't interface properly with the main block and to me it looks like a marriage of two different cassettes.

    Thanks for the info about the hoods.

    Not sure if this is relevant but..
    I had an old bike with narrow spacing at the dropouts. I used S/H 9 speed shifters and used a 9 speed cassette, but used an old freewheel and dropped a cog off to fit it in the space. This worked fine (but one click spare), but an 8 speed cassette wouldn't have shifted properly.

    Previous owner may have mixed a block from (say) 9 speed setup with loose cogs from something else, hence spacing mismatch?

    Probably best post a picture. It sounds like, exactly what you're saying. Maybe someone has miss matched a cassette. That would be fine if the miss matching was done and it's all from an 8 speed cassette. If it's tight and shifts ok, then it's probably fine though.

    From the exploded views here Sora 8 speed cassettes would appear to have the first 6 sprockets bolted together then the 2 smallest loose and with built in spacers
