For a bit of Fun over the next few weeks I will be posting an incident from the Workshop.

They will range from builds, to customer fixes and the odd mess up from elsewhere.

Oh and the odd trip to seen new bikes.


Bike specs and brake positions will be different to UK bikes

    Today's instalment.

    a Dad droped off 4 bikes and a wheel today.

    generally it was just for fixing punctures.

    here was one.

    Other issues that will be raised with Dad were the dead headset and the Fubared forks.

    Not to mention the seat post shims.

    Looking forward to seeing more of these, thanks Nick.

    Must remember to turn my seatclamp through 90 degrees in the morning.
    I've added a signature to prove it is still possible.
  • I'm loving that seat tube adapter, very neat!

    Is the drive-side chainstay held together by a bit of hosepipe as well?

    Todays instalment.

    Credit where it is due the lad had done his best to fit a headset but using a hammer is not the best way.

    anyway back it came for a new headset and i spotted a few oddities.

    that start nut was a bit high.

    and the steerer a bit low.

    and a rather odd caliper set up.

    img0409l.jpg

    the pads were only working on the outer half of the braking surface.

    :lol:
    did he think that moving the calliper outwards was going to have the same effect as running a bigger disk?

    See, IF those were teh only calliper bolts I had, then what I'd have done is cut them down, or (if I didn't have a hacksaw) use the nuts on the OTHER side of the calliper.
    So it would have gone, brake mount, calliper, nut done up tight locking it all down onto the bolts.

    But the brake is an avid so it needs the adjustment washers.

    ah, right. I thought it was a hayes or something.
  • I love bodges. You can almost picture someone trying to figure a way of making the caliper work or getting the stem to fit, then standing back, smiling smuggly and thinking "job done".
  • lol, great thread! you must see some pretty interesting "engineering solutions" in your line of work.

    He booked the bikes in to get punctures fixed?! Is that all?

    And anyway, how the hell did you end up with a bike business in Sweden in the first place?

    nothing much today, lots of services, drivetrain replacements and a this.

    img0410f.jpg

    Yes it has brakes and gears!

    but how many?

    1 gear
    I win? :D

    Btw, it's a nice rear suspension bike.

    1 brake, 3 gears?
  • nicklousenicklouse Posts: 50,675 Lives Here
    one brake and 2 gears and no cables.

    2 gears?
    Is that by design, or failure? (I take it it's a geared hub with a coaster brake)
  • nicklousenicklouse Posts: 50,675 Lives Here
    nope does not need any cables.

  • Interesting ride, that chainring looks a bit flimsy, also is that some kind of generator on the seat stay next to the rim?

  • that sram hub gear which is fixed free at the turn of an allen key?

    I'm damned intruiged now!

    I'm gonna say a Sachs Duomatic. It shifts gears when you backpedal and also has a coaster brake. Someone abandoned a step-through with one of these near my apartment complex: been thinking of doing it up, but it'll probably turn out to have been reported stolen or something.

    The thing on the seat stay is a lock, you turn your key and then rotate the thing 90 degrees so it goes through the spokes and stops the wheel from turning.

    ah that makes sense, thought it might have been a dynamo for a light or something.

  • Taking advantage of the elderly. How can you stoop so low?! :(
  • nicklousenicklouse Posts: 50,675 Lives Here
    Today was fun.

    Dynamos and customers bodged wiring. arrrghhhhh.

    thats better.

    so it was a few services and then an insurance replacement build.

    img2824.jpg

    yes thats right this is an insurance replacement.

    then it was a fork extension on a Tora Solo air from 100mm to 130mm for another build which should be finished tomorrow.

    then it was round to a mates to press in some pivot bushes in a Klien.

    Well today was a tad slow.

    but I had a build to finish. most of it was done last night but i Fing hate shimano low level brakes as the suck, also as the discs are not round they were catching on the caliper, also the hoses were way too long and needed shortening. Also i was sure i had seen some Juicys in the shop somewhere and they are easier to space out with out it looking like they are.

    Found them but on piston was rattling about. Mmm ok the hoses are the right length, shimano back into stock and sort the avids. a bit of grease and put the piston back in reassemble the caliper and bleed. sorted.
    Fit do the gears and test ride.

    img0413vx.jpg

    then it was onto put a bike together for as little as possible for a teacher with 5 kids

    Take one 26" wheeled "MTB" that has been in the scrap pile out side for a year or 2. and some 28" wheels with internal gears.

    Done.

    rides Ok.
