    Lakeside bro and you get to ride on the Dartford tunnel....

  • What's a good bike shop in SE?

    Need to get them to bleed a hydraulic brake for me...

  • I'd stick it in the car and take it to:

    Brixton Cycles (guess)
    Cadence (Crystal Palace)
    Blue Door (Crystal Palace)

    Cadence or Blue Door are going to be closer, and you can park in Sainsbury, whereas parking near Brixton is a bit of a pain sometimes.

    What is the issue?

    Trapped air or fluid refresh?

  • I'd second Brixton Cycles - one of the few LBSes that I've ever actually enjoyed going into. Dunno whether they do hydraulics, but they have loads of MTBs around the shop.

  • Pretty sure they do.

  • they do hydraulics

  • and are utterly lovely people

    Got new brake setup (TRP Hylex) and the rear is going to be run internally... So it will need bled when at the same time.

  • and are utterly lovely people

    Apart from that ginger bearded one, he's an arse.

  • Congrats on the new set up.

    Are you doing the fitting yourself? As bleeding is not a issue, if you need it done quickly.

    Also wouldn't mind some feed back, as in how good it is as I'm tempted to build my super galaxy as a disc braked tourer with bar end shifters.

    I think I'm just going to get Brixton to do it for me. Less hassle.

  • Which thread could do with this GIF?

  • Which thread forum could do with this GIF?

    Hmmm...

  • The bike porn thread.

  • am I correct in asuming that adding a single half link to the chain will position the wheel just about 5-7mm further back? gearing is 42x18

  • thanks.
    don't get the sheldon link btw. no answer to my question there...

  • Most newer frames made for derailer use have vertical dropouts. This is convenient when you're actually using a derailer, but causes a complication when you wish to simplify your drive train, either to singlespeed, fixed-gear or an internal-geared hub. The simplest way around this is to install a chain-tensioning pulley of some sort. This is not an option for fixed gears or coaster brakes, but is the easiest solution for freewheeling bikes. Even for singlespeeds, though, it is nicer to be able to do without a klugy and inelegant chain tensioner.

    Fortunately, most "vertical" dropouts are not exactly vertical: they usually have a bit of a slant. As a result, it is sometimes possible to use this type of frame. To make it work, you may have to play games with chainwheel sizes. One of my fixed-gear bicycles is based on a Cannondale touring frame. It happens that there is just enough adjustment to make it work with my preferred 42/15 combination. If the chainstays were a bit different in length, I could replace the 42 with a 41 or 43.

    Adding or subtracting a link in the chain will move the axle 1/2". Changing either sprocket size by one tooth is the equivalent of moving the axle 1/8" (4 mm). Thus, if I wanted a 5.75 gain ratio (75" / 6 meter gear), I might first try a 42/15, this gives a gain ratio of 5.77 (75.6" / 6.05 m gear). If the chain was too loose, I could take up 1/8" (4 mm) of axle movement by replacing the 42 with a 43. This 43/15 combination would raise my gain ratio to 5.91 (77.4" / 6.19 m). Alternately, I could get the same axle position with a 42/16 --5.41 (70.9" / 5.67 m).

    If I was not happy with these choices, I could add a link to the chain and switch to a 45/17 --5.45 (71.5" / 5.72 m) If I added two links to the chain, I could get the same axle position with a 48/18 --5.49 (72.0" / 5.76 m)

    Another possibility would be to do a little bit of filing at the back of the dropout to let the axle move back just a bit.

    It is also possible to grind or file a flat on each end of the axle to allow a bit more adjustment, like this:

    This bit I guess.

    You've covered the actual answer with your range. It's actually 6.35mm, plus a few microns depending on chainstay length and difference between chainring and sprocket.

  • ^ktx
    and I take this as a yes:

  • I failed miserably trying to get the number before the passenger knock the phone off my hand, can anyone figure out the number please?
