Updated 8-05-06 Some shots of a
major modification.
Full left view
the addition of Tandem crossover chain system
for the sync chains.
Shimano Deore XT Tandem 170
mm Cranks.
This bike had tapered square crank shafts so to keep
the cost down on this modification I kept them rather than changing to a
splined bottom bracket. I had an old right hand Shimano 3 chain ring
crank so I bought 2 captains Shimano Deore
XT Tandem 170 mm Cranks I used one complete set up front for the
captains cranks and the left crank with the sync gear for the stokers
and used my old Shimano GT 170mm crank for the strokes side.
This saved me a lot of money I
picked up the 2 Shimano Deore
XT Tandem 170 mm Cranks on eBay for $150.00 |

Close up view of
the stokers crank and homebuilt chain
Idler tensioner made from a rear derailleur
and the addition of 3 chain rings on the
opposite right crank. |
 |
Spring loaded idler
made from a old Shimano rear derailleur to keep the sync chain tight with light
pressure.
The H & L adjusting screws are used to fine tune alignment to the
sprocket. |

Next
modifications are the replacement of the front
and rear derailleur thanks to Brian (co-worker
& friend) who
was kind enough to give me some old parts he
had
to do the swap with they are much better
units but brackets
need to be made for this mod. will be done
soon...
|
|
Update: This original rear
derailleur was a cheep one that had the hanger on it the frame
needed a way to mount the Shimano 600 derailleur.
I found a adaptor that attached to a frame, the
frame did not have a built-in derailleur mount on the right dropout.
This adapter is threaded so you can use any derailleur with it.
$3.95
This bracket was bought at Harris Cyclery
http://sheldonbrown.com/harris/
Harris Cyclery sells other parts also.
My experience with them was good with fast delivery. + |

Pedal Upgrade
2 sets of Forté Campus Pedals
This set of pedals has a platform on one side
so you can use your normal shoes, flip it over
and it has clips that are compatible with
Shimano SPD cleats so it can be used with or
without toe clips, with or without cleats.
I also wanted straps for my street shoes so
I also use a set of Winwood Instep Pedal
Inserts
which are clipped into the toe clips.
If you are going to use biking shoes the
Winwood Instep Pedal Inserts are removed and you
clip straight into the pedal.
Both Captain and stoker are equipped with
the same setup.

The old stoker stem was replaced
the seat bar is a little of an odd diameter
being an old bike so I found this front stem at a
local bike shop and picked it up cheap.
I made a shim for it so it fit.
Its actually an adjustable stem with built in shock
with tension adjustments worked out well.
UNO Adjustable Stem $12.00 |

Kids stoker crank set installed.
This allows the smaller kids to join in on riding
as the stoker.
They really like the thought of peddling
on some short rides.
It is installed with 2 Allen bolts that clamp onto
the stoker seat post, so installation and removal
is fast, remove the chain and ready to go with out it. |

Upgraded from a 6 to 7 speed freewheel using a
Shimano non "Alpine" version of the Mega 7 freewheel
substituting a 28 tooth sprocket for the 34.
This freewheel has 11-13-15-18-21-24-28 setup.
Because of its unusual design, the larger sprockets have to use a larger
spline pattern than other Shimano freewheels. Therefore, it is not
possible to customize the gearing on this freewheel.
Harris Cyclery $19.95
Tandem now has 21 speeds
I added a 1mm shim to get the proper clearance
for the frame for the 7 speed freewheel.
