    There's a keen cyclist I know who tried to do it on a fixed gear bike a few years ago, but - topical to the thread - his chain snapped.

    Personally I think they look wrong with the huge cassette on the back.
    I agree and had thought similar with earlier posts. Surely some of the wear would be on the extremes of the cassette to the front derailleur? Without that, does more wear happen on the chainring? Either way, it's wear to the chain.
    I did look at putting a single chain ring on my 29er as I already have a dinner plate of a gear on the back. However I've max'd out the gears on a couple of times so dropping the large chain ring in favour of something in the middle is not going to work. And of course, it just looks wrong!

    Something new sells, yes but only to people with more money than sense.

    I did the Polaris 2 day events (similar to KIMM) on a tandem a few times

    We did talk about doing the PPPCX.... but that was as far as it got

    I did fancy the PPPCX on a fixed

    This single front ring and huge cassette combo seems to be de-rigeur on e-MTBs. Maybe this is where the trend is coming from?

    So continuing with my daft questions, and having now spent getting on for 500 miles 'gaining' experience on my new gravel bike, I'm now thinking of adding to my biking repertoire with an alternative, gnarlier wheel/tyre/rear cassette set up that I can pop on and off, depending on my intended route for the day. To be fair the bike is already pretty gnarly, but I like the idea of being able to mod/twat about with the bike at my whim.

    I appreciate that most of you guys are more geared up for pure road biking stuff but any steerage you can give me would be great either way. I don't want a mountain bike by the way (at least not yet anyway) but do like the idea of making my existing bike more flexible

    My new set up would be with 650b wheels (27.5 inch), wider tyres and maybe a lower set of of rear wheel cogs

    My bike frame is 'medium' and with the 700c wheels attached I'm just tall enough to fit comfortably and stand over the crossbar without knackering myself. I've got everything set up well and am really comfortable in the saddle. I am quite small though, at 5 ft 7, so I figure that the 650b wheels will seem a super fit for me, giving me small drop in height and making for a more compact unit. With their smaller circumference they'll also effectively act as a lower gearing I'd guess. I have quick release wheel fittings so I'll need to make sure the new wheels are compatible with this (and maybe need some kind of QR conversion kit?)

    My existing tyres are 40mm but, with the new wheel size, I'm thinking of some 42mm gravel bike tyres. I think the bike will have sufficient clearance for these (the spec says up to 50mm on the front and 44mm on the back) but I understand that tyres can come up wider than their spec so I may have to be careful with tyre choice

    I now understand a point that had originally appeared complete gobbledygook to me in that I can fit a new lower rear set of cogs to my new back wheel, using a CS-HG50-10 Shimano cassette, which gives me a 36-tooth sprocket - two extra sprockets than what I have at the minute I'm thinking/guessing which can only come in handy around here

    Having done a shed load of internet searching, I've found a possible set up of what might fit the bill:

    Shimano CS-HG50-10 11-36t cassette
    Fulcrum Rapid Red C24 gravel wheelset
    WTB Resolute TCS Light Fast tyres

    Tell me why I'm being stupid and what if anything I've missed

    Thanks

    Wheels and tyres can be quite a personal choice but your new cassette will need to compatible with your chainset.
    You mention extra sprockets - so that won't work with your shifters which will be indexed for how may you have now. Not sure what derailleur you have but you may need to check that will handle the large sprocket too.

    Iím probably using the word sprocket when I mean teeth. I understand that the cassette is compatible but youíre giving me doubts now

    That's probably ok then.
    One other thought is that you will need rotors on your wheels so need to make sure you can fit correct ones for your calipers on the new hubs.
