How to fix a Bugaboo Handle
If you are not a handyperson type, take these instructions
to you local Bicycle Mechanic or Small engineering shop.
The bugaboo handle fault is caused either by two small
plastic pins shearing of a plastic disk that actuates two metal locking
rods. Why bugaboo uses a plastic
disk for this critical component is beyond me! Or a broken locking rod
1/.
Remove the capped star lock washer. This is the hardest part of the job. Most people try to leaver this off in
the hope of re using. First
problem with this is you will mark or damage the surrounding plastic second is
star locks are not intended for reuse and will never hold as well as when first
used, so best find a new replacement.
A hardware store should be able to source some for you. Quickest way to remove a capped washer
is to carefully cut a slot in the dome with an angle grinder and then use a
large screwdriver to carefully prize one side up so you can fit a
screwdriver. Note the walls of the
aluminum hub axel are thin and easily distorted, make sure you only lever the capped
star lock and not hub axel. Use
one screwdriver as a support and another to lift off the capped star lock.
Note it is best to open and repair one side at a time, so
your moving and flexing one side of the handle does not dislodge parts in the
other side. The hub and disks are
mirrors of each other and not interchangeable. The side with the brake lever is left The Bugaboo parts will
have an "L" after their serial numbers.
2/. The lock
mechanism is very simple; a wire rod rotates a plastic disk. Check the hubs for ware. If too badly worn or damaged you will
have too much movement in the locked position. The Frog and Chameleon use the same plastic hub find another
frame to salvage hubs from. They
are held in by a single aluminum rivet.
The disk has two plastic pins that move the locking rods in
and out of the inner hub into and out of the outer hub. You need to either repair the disk by
drilling out the pin stumps and finding a replacement metal screw you can fit /
glue in. Or (my preferred choice)
have a new metal disk fabricated that will last a lifetime.
3/. Reassemble
handle locking hub and check operation.
If wire rods seem to be in the incorrect position, loosen the top
plastic fittings where the handle extends from by removing the small
self-tapping screws and wiggle things into alignment. (I use a small amount of
the grease used for taps to give a smooth action) If all is working well fit the new capped star lock on
the hub shaft and tap home. To protect the dome finish I use a large socket
from my socket set and an old rubber washer from a toilet cistern. Repeat operation on the other side
I have parts available laser cut metal disks with stainless
steel pins, replacenment locking
rods in stainless steel and capped star lock washers you can contact me at [email protected]
