26 tooth inner chainring - With the chainset removed, use a 5mm hex key to remove the 5 bolts that hold the
inner chainring in place. Note if there is a recessed hole (for the bolt or nut head) in the chainring where the
bolts are fitted; the new ring will have to be re-fitted in the same way. Remove the ring, and replace it with
the 26 tooth ring, and then replace the bolts. Tighten them evenly in a pattern, working on one bolt, then
one opposite. Replace the chainset on the trike.

55 tooth outer chainring. To gain proper access to the chainring bolts, it will be necessary to remover the
inner chainring first, following the instructions above. Remove the 5 bolts that hold the middle and outer
chainrings onto the crank arm. You will need to hold onto the nut (the part against the middle chainring)
using either a large flat screwdriver, or special chainring tool (available inexpensively from most good bike
shops or ICE). Note how the bolts fit onto the rings. Swap the large chainring for the optional 55 tooth one,
and reassemble. Be certain to tighten the bolts up evenly before riding the trike.
If you have changed either chainring, you need check the chain lengths again (as shown in section 2) to ensure
that the trike has the correct length of chain.
4.12 Chainring guard
The chainring guard is fitted onto the bottom
bracket shell. If the chainset has been installed,
you will need to obtain a crank extractor in order to
remove it. With the chainset removed, slacken
the single bolt on the chainring guard, and slip the
guard onto the bottom bracket shell, ensuring that
the guard does not touch the front derailleur.
Replace the chainset and tighten. To adjust the position of
the guard, slacken the bolt and rotate the guard until the
top edge is close to, but not touching, the front derailleur.
While turning the pedals, check that there is clearance for
the chain when it is running on, and shifting between, all
three rings.
