  • Didn't look but just assuming it's just flat bits, apparently it's too difficult to just use a wrench though, I've not fucked about with one before so it could work but if it's anything like that seatpost we'll need all the help we can get.

  • USED THIS SHELDON TRICK BEFORE.. WORKS WELL


    If you don't have a bench vise, or if the vise technique happens to not work well on your bike, you can make a universal fixed cup tool for less than a dollar (assuming you have access to a couple of large wrenches).

    The tool is an imitation of a $40 shop tool that fits into the fixed  cup as a crank spindle would, and pinches the cup. You apply unscrewing  force to the tool, and it transfers this force to the cup with this  tight friction fit. 
    
    The tool consists of a large bolt, a nut or two, and a few washers.  The size of the bolt is not particularly critical, as long as the bolt  is strong enough not to break, but small enough to fit through the hole  in the cup. I used to use an ordinary 1/2-inch, 13 TPI hex bolt (also  called a "cap screw"), which served me well for quite a while. It  finally met its match on friend's Schwinn that had an unusually tight  fixed cup; the bolt snapped in two before I could remove the cup. 
    
    Now I use a 5/8-inch 18 TPI hex bolt 1 1/2inches long, with a nut, a  flat washer, and four lockwashers. The 5/8-inch size is the largest  standard size that will fit through the hole in the cup. This bolt and  nut both take a 15/16-inch wrench. With my 1/2 inch drive Craftsman  six-point socket set, the 15/16-inch socket is also the largest size  that will fit into a normal bottom bracket shell. 
    If you have some other brand of socket, check the fit before you buy  the bolt and nut-you might need the next size down (9/16-inch). 
    

    The bolt is put through the cup from the inside of the bottom bracket, and the nut screws onto it from the outside. There should be washers on both sides of the cup. You will need a socket wrench and a short extension to tighten the bolt from inside the bottom bracket, and a box wrench for the nut. A large socket wrench will not fit into the cup, so you will need some small-diameter washers to space the head of the bolt out so that the socket wrench can reach it. This is what I use the four split lockwashers for. I didn't need lockwashers as such, but the readily available flat washers were too large in outside diameter to fit into the cup.

    To remove a right-threaded fixed cup (French or Italian), tighten the  bolt with the socket wrench from the inside of the bottom bracket,  holding the nut with the box wrench. Once the bolt is as tight as can  be, keep on tightening it, until the cup screws itself out. Once the cup  starts to move, turn both wrenches together.    
    To remove a left=threaded (British, Swiss or Raleigh) fixed cup, hold  the bolt with the socket wrench and turn the nut with the box wrench.    
    

    Use the same tool the opposite way to install the new fixed cup.

    You might worry about damaging the cup, but this is not likely to  happen. The washer doesn't usually come into contact with the bearing  surface. Even if it did, bearing cups are made of extraordinarily  hard,  heat-treated steel, much stronger   than  that used    to  make  washers.
    
  • That was one fucking stuck seatpost, needed about a litre of gt85, a vice, some swearing, fire and a hammer. I'll be in town later for a beer with my brother but is a bit late now.
    The 20t rear would be perfect for it although the freewheel that's on there will be a bitch to remove as the axles been spaced out a bit so the tool won't fit without removing bits off it. I'll bring stuff to polo tomorrow to have a go.

    Finally the solution was hold the seat post with this:

    What the name of this?

    And then turn the bike from one size to the other while doing outward force.

    After all things rob said and a litre of gt85.

    Nice work!

  • Vice^

    Mine ain't quite that fancy looking.

    I was reading about the Sheldon tool earlier, do you have one or the bits to make one?

  • Victor, i have 2 Schwalbe Marathon plus tyres, 26x1.75 £20 for the pair if your looking for cheap slick tyres

    I can be interested, but it seem not to be a cheap price, I've seen on ebay the same ones new for 17£ delivery included

    are the same ones?

  • No, Ste is selling Marathon **PLUS **tyres, which are about £50 a pair I think.

  • ^ That's for one tyre only. £20 for a pair is well cheap.

  • ok cool, can we see it on thursday Ste?

  • Rob I've not got the bits, last time I got them from the hardware store on Dickinson road..

  • I can be interested, but it seem not to be a cheap price, I've seen on ebay the same ones new for 17£ delivery included
    are the same ones?

    on that link there £13.99+£2.79 postage = £16.78
    thats £34 for 2

    im selling them for £10 each

  • ok cool, can we see it on thursday Ste?

    yeh il bring them out on thursday

  • Slow maths

  • yes I get confused with the main photo where appeared 2 tyres... thanks anyway!

    Another thing, I would like to buy two 2′x4′ sheet of corrugated plastic to keep safe the spokes. Do you know any shop where I can buy it? or if there are any place where buy it already done for a reasonable price I don't mind.

  • 'For Sale' signs seem to be perfect for the job. I found an old advertising board from the election a while back that's not quite big enough unless I get creative and also find a way to cover up the Labour party logos.

  • +1 for For Sale signs....

    sure somebdy will have a cover knocking around, i might have one at home...

  • jaja ok cool!

  • +1 to jaja

    Manchester bike polo has its own Rik.....!

    (No offence victor, i'll explain when i see you)

  • +1 to jaja

    (No offence victor, i'll explain when i see you)

    I can't offence I don't know what is Rik...! jaja

    I use to say when chatting jaja in spanish in stead of haha or lol

  • With a 20t rear you'll want no more than 32 at the front for polo.

    thats what i run, perfect for gettting to polo and playing,

    rather run 20/30 but getting about was a big effort

  • Victor, London used to have player called Rik who was from Spain, he used Jaja, and then so did all of London polo.......!
