· Check when the brake blocks hit the rim. If this ‘bite point’ comes after just a short movement of the levers, you’ll have to
adjust the cable if you want to adjust lever reach (see page 23). Otherwise, the brakes may rub on the rims after the reach
adjustment. If, however, the brakes only bite after the levers are halfway to the bars, you have some ‘play’ with which to
adjust lever reach.
· There’s a small adjuster screw just near where the cable goes into the lever housing (see arrow on diagram). Screw this
adjuster in, and observe how the lever position changes.
· When you’ve reached the desired position, you must check that there’s still enough available motion so that there’s a little
lever movement before the brakes ‘bite’.
Danger
: You shouldn’t be able to pull the levers all the way to the handlebar! Maximum braking power should be reached before
this!
Adjusting angle of handlebars, bar ends and brake levers
The handlebars ends on the Frog bend at a slight angle. Adjust the handlebars so that your wrist joints and hands are relaxed and
are not too sharply angled outwards. To adjust the handlebar position by turning the handlebar:
· Open the hex bolt on the front of the stem.
· Turn the handlebar until it reaches the desired position.
· Check that the stem clamp is exactly in the middle of the handlebars.
· Re-tighten the hex bolt with a torque of 12-14Nm.
Once you’ve adjusted the handlebar angle, you need to adjust the brake lever position.
· Loosen the hex-key bolt on the lever housing clamps.
· Turn the lever on the handlebar. Sit on the saddle and grip the levers with your fingers. Check that your hand makes a
straight line with your forearm.
· Re-tighten the bolts and check that the brake lever housings don’t twist!
Danger
: Always be sure that securing bolts on stem, handlebars, bar ends and brakes are tightened with the appropriate
tightening torque. The appropriate values are listed on page 41. Otherwise, it’s possible that parts may come loose or break. This can
lead to serious accidents.

Changing the rear elastomer
The Frog is fitted as standard with a red elastomer, which is suitable for a very wide range of conditions. It can, however,
sometimes make sense to fine-tune the riding qualities to your personal taste by changing the rear elastomer to reflect your
particular weight, riding style and the state of your local roads. A softer yellow elastomer and a harder, green one are available. To
change it over, move the rear swing-arm clear and pull the elastomer off with your hand. The following table may help you select
the correct elastomer. Please note that elastomers get ‘harder’ at low temperatures. It could therefore be a good idea to change to
a ‘softer’ elastomer in winter.

Changing the front elastomer
The front elastomer can also be exchanged for a harder version. The standard version is hollow, while the harder version is solid.
The elastomer can be pushed out of the spring with a screwdriver.
PAGE 17, How do I use a quick-release?
Quick-releases hold both seatposts and the height-adjustable stem in position.
Danger
: an incompletely or improperly closed quick-release can result in parts coming loose, and hence in a crash, possibly
resulting in serious injury!
A quick-release consists of two basic parts:
· The lever on one side of the hub – this provides the clamping force.
· The adjusting nut on the other side: by adjusting this on the screw thread, the clamping tension can be adjusted.
· Open the quick-release. The inscription ‘Open’ should be visible on the lever.
· To close the quick-release, move the lever inverse. At the start of the lever’s motion, for, say, half of its movement, the lever
should move very easily, without any clamping action.
· In the second half of the lever’s movement, the force on the lever should rise considerably. At the end, it should be hard to
move. Use the ball of your hand. In its final position the lever should lie parallel with the bike, and should not stick out to
one side.
· Check the security of the lever by attempting to twist the lever. Press on the end of the lever from above.
