Shifting

[Mark]

Oky folks, I need some help here. I have just "graduated" from a 1989 Trek
1200 to a 2006 Trek 1200. The new bike has the shifters incorporated into
the brake lever. How the heck do you shift these things? I was going to a
parking lot to get familair with the bike and pushed the lever on the right
hand side until it was on the smallest cog. But now when I push the lever
it won't do anything. I do not know how to shift to the bigger cogs. This
also has three chainrings in the front and I pushed the lever on the left
hand side until it shifted to the smaller ring but now it wont move back. I
just got this bike tuned up and I am sure the bike shop wouldnt have
released it if it wasnt shifting right. Help!!

You push inward on the small lever to shift to a smaller gear. Push inward
on the larger lever (the brake lever) to shift to a larger gear.

go back to the bike shop and ask their "dummy specialist" to show
you how to shift gears.

sheesh.

Mounting them on the downtube might be a bit of a challenge.

Physically speaking:

The brake-lever-shift works the cable against the derallieur spring by
winding the cable with a ratchet mechanism. The left brake lever moves
the front derallieur to the right and the right brake lever moves the
rear derallieur to the left. Shifts from inner to center ring requires a
lot more and firmer movement than from any other ring because of the
geometry of the chain and the derallieur cage.

The small/release-lever releases the cable ratchet mechanism in the
shifter mechanism one shift, so the left lever moves the front derallieur
to the left and the right lever moves the rear derallieur to the right.

You may experience a 'stutter' shift to-and-from the center front chain
ring from the inner ring. It's used to slightly change the front cage
position but doesn't actually force the chain to shift to another ring.
It's there to enhance derallieur/chainline compliance from front to back
cogs (keep the chain from rubbing on the front derallieur cage) caused by
shifting the chain from the extreme inner cog/outer cog limits on the
rear cluster. It can be felt as an 'almost' shift from inner to center
or from center to inner chain rings, usually by not fully depressing
either the brake lever shifter or the smaller release lever.

Unfortunately, only practice will make this second-nature since the left
and right shifters are alike in physical operation, but opposite in
actual gear ration effect.

Bar-end shifters would likely work [1].

[1] Do the newer carbon fiber composite handlebars with ovoid
cross-sections have a circular cross-section with standard I.D. so
bar-end shifters [2] and normal end plugs will work?
[2] The combination of carbon fiber composite handlebars and bar-end
shifters does seem rather odd.

I've never thought to look.

IMO, carbon fiber-reinforced-plastic handlebars seem rather odd.
Along with CFRP stems, seatposts, seatstays, etc.

Probably.

FWIW, carbon fiber aerobars are designed to work with bar-end shifters.
