    Huzzah!

    A startling 73KGs of manly log delivered by human power and ingenuity (little of it mine!)

    I can't imagine loading the full 90kg onto this now though! :O

    I stand in awe of your manly log.

    Oo-er!

    I did have to keep it bottom gear all the way home (and I went the long way around, via Russell Rd) and had to walk up to the house at the end.

    The hub gear was really playing up. Adjust left, adjust right, I just can't seem to get it happy. Trying to decide whether to dismantle it or even send it back..

    70kg a struggle? I've heard folk say they take 100kg no problems and i've never believed them, think it was the gearing or is it just a stupid thing to try?

    Should keep you warm for a couple of days though.

    Two issues for me - low gear of just under 40" means I can't go slower than 6-7mph, which is a lot going uphill with a total weight (including rider) of 1/3rd of a mini...

    Then when going above ~20mph (there are some downhill bits!) there's a bit of a risk of the tail "wagging the dog" handling-wise. For instance if you take a big-ish speedbump, there's a sudden deceleration then the trailer pushes you forwards as it rolls down... oo-er!

    It gets much worse when trying to mount kerbs (tram diversion at Russell Rd, a bystander had to help me boost the trailer up onto the pavement, I had vertically jacknifed!).

    What are you planning to do with it?

    We picked up two sections of a tree trunk from our nursery last week. They are in my garage waiting for me to saw them up into fire wood sized peices.

    Dave, why not speak to Peter Eland at Velovision? His ancient yellow Tufftrax has had a succession of hub gears (currently a SRAM 9spd, I think) and that's what he uses for towing huge loads. Failing that, get in touch with Tulyar here on CCE - he has some experience with trailers and hub geared bikes too. Edit: Someone's ears are burning.

    If the hub gear can be fettled properly, perhaps a Schlumpf Mountain Drive would give you the low ratios you need?

    Good work, fella!

    If they came down recently I suggest leaving them in the garden for a year before burning/crafting.

    40"!?! my summer tour was about 70kg total and my lowest gear was about 22"! And I felt an extra gear wouldn't go amiss.

    I've never got my head round all this inches of gear thing. Is there a FAQ somewhere that explains what it is.

    The equivalent diameter in inches which a penny farthing's (directly-driven) front wheel would have to be to provide equivalent distance-travelled-per-pedal-revolution of a particular gearing.

    But how does one, for instance, convert the combination of, say, a 52 tooth chain ring and 16 tooth sprocket on a 700c wheel, into penny farthing inches. And can't we do it in centimetres these days?

    @instography as always, Uncle Sheldon has the answer

    OK. So that makes my single speed an 85.7 inch penny farthing. In the spirit of the thread, does that mean I've got a big one?

    That's a behemoth. You'll cause a lot of jealousy in the changing room with inches like that.

    86" - crikey!

    That's just over 15mph at 60rpm... don't fancy having to climb everything at that kind of speed! Mine was a more modest 66/72" flippable.

    Maybe I should check my sums. It's a 52 tooth chain ring and 16 on the back. It's good on the flat and you can blast up wee hills. It's a bit of a struggle on Arthur's Seat.

  18. Cripes! I had a 44 x 16 for a comfy 72".

    And I'm hankering for one again...

    72" and 63" here. With my practical hat on, the smaller is the better gear, but it limits top speed so much it's incompatible with my fun hat. I don't think I'd like to go as high as 86" unless it was a track bike, though.

    Trying Arthur's Seat on that is pretty epic. I struggle on 72" as 44 x 16. For reasons of dropout I'm going to need to change that either to 68" or 75", but I need to get a bit fitter if I'm to do Arthur's on the latter.

    Maybe you need to take a leaf out of BR's book, with a push pull configuration, a couple of trailers with a bike in front and another in the rear. Would need some practice keeping everything taught.

    More sensibly (but not all that senisble) you could put a disk brake on the trailer and substitute the rear brake lever to the trailer, might help a bit.

    I'm slightly ashamed to say i've got a rather low 64" gear on my ss...

    The tree that had fallen into Duke St Tesco's car park was gone last night.

    "at Russell Rd, a bystander had to help me boost the trailer up onto the pavement"

    The way the diversion has been routed (with kerb ramps) suggests that you are /supposed/ to cycle on the big wide bit of pavement with the line of bricks down the middle.

    This bit has always been unclear to me (i.e. pre-tram works). It kind of looked like it had been designed as a joint use path although I never used it as such.

    With the diversion in place I have started (when heading south) going onto the pavement at the entrance to the flats.

    68" on my singlespeed. I can manage Arthur's Seat on that, but it pays to be warmed up - I gained a few weeks of sore knee last year from doing a sit down lap straight from home.

    My knees hurt just contemplating Edinburgh and 86".

    A mere 66" on my single speed, which won't get me to any great speed on the flat, but keeps hills sort of manageable...

    (Sorry I've put all the trailer stuff in the correct thread now).

    I'm afraid I take the easy way out when collecting wood....
