The F.I.T. system makes it easyfor a rider to adjust the height ofthe handlebars. An integratedgroove in the stem keeps thehandlebars in the correct positionperpendicular to the frame of the

bike. Distance marks on the stemitself let the rider know to exactlywhat height he has adjusted hishandlebars.

WARNING: If you are inany way unsure of how to

make these adjustments, takeyour bike to a qualied bicycletechnician for professionaladjustment.

WARNING: Do not loosen thetop cap.

The newly developed Axis stemmakes it easy for a rider toadjust the height and angle ofthe handlebars. An integratedgroove in the stem keeps thehandlebars in the correct position

perpendicular to the frame of thebike while an adjustment jointin the middle of the stem allowsfor angle adjustments. Distancemarks on the stem itself letthe rider know to exactly whatheight the handlebars have beenadjusted.

Additionally, a second groovein the stem makes it possible to

take off the stem and handlebar,reposition it 90 degrees and putit back onto the handlepost. Inthis way, the stem and handlebarcan be securely attached to thebike when it is folded and storedinstead of dangling loosely fromthe bike.

WARNING: If you are in

any way unsure of how tomake these adjustments, takeyour bike to a qualied bicycletechnician for professionaladjustment.

The latch of the handlepost hinge on Dahon foldingbikes should be checked before each ride to make surethat it closes tightly to secure the handlepost. A closedhandlepost hinge with a properly adjusted and securedlatch should have little to no side-to-side movement. Inspectthe handlepost periodically to ensure that it is properly

adjusted.

CAUTION:Do NOT cycle with a loose handleposthinge.

To check if the latch needs to be adjusted, close thehandlepost hinge and then close the hinge latch. If thelatch is loose after closing or if too much force is required toclose it, then the latch needs to be adjusted.

WARNING: If you are in any way unsure of how to

make these adjustments, take your bike to aqualied bicycle technician for professionaladjustment.

Different versions of the handlepost hinge can be found onDahon bikes. They look slightly different, but the adjustmentof the hinge latch is basically the same for both versions.Please check the handlepost hinge to nd out which hingeversion is used and follow the appropriate instructions foradjusting the latch.

NOTE: For details about how to open the hinge, pleaserefer to the included folding instructions.

These instructions are only for the adjustment of the hingeitself. Regarding the adjustment of the headset, please referto the headset instructions.

Bikes equipped with the LockJawhinge look just like a regular bike you have to get up close and lookreally hard to see where the bikefolds. To ensure safe and troublefree usage of the LockJaw hinge

and your bike, please read thefollowing instructions carefully.


make these adjustmentsyourself, take your bike to aqualied technician forprofessional adjustment.

The LockJaw hinge (one locatedon the top tube and one on the

down tube) has three componentswith each fullling a differentfunction.

Adjustment Bolt adjuststhe tightness of the LockJaw

mechanism.Pivot Bolt the actual hingeaxle around which the twohalves of the frame rotates. Thepivot bolt can be adjusted totighten or loosen the hinge.

WARNING: ONLY openthe LockJaw hinge with

the OC bolt.

WARNING: As a generalrule, the pivot bolt will

not need any user adjustment.Do NOT try to open theLockJaw hinge with the pivotbolt. ONLY adjust thetightness of the LockJawhinge with the adjustmentbolt.

Tools Needed:6 mm Allen key

Overview

There are two versions of theLockJaw. Please check yourbike to determine which Lock-Jaw version is used and applythe appropriate instructions.

Adjust the Tightness of the LockJaw (The Adjustment Bolt)

The LockJaw is exceptionally stiff and stable, but will require periodinspection and adjustment to ensure that it is properly tensioned.Adjust the LockJaw according to the following instructions.

Version A

Tools Needed: 6 mm Allen key

NOTE:Only turn the adjustment bolt in small increments (e.g. a 1/8turn) each time otherwise you might over tighten or over loosen it.

Do not over tightenthe adjustment bolt. Over tightening theadjustment bolt will cause damage to the meshing mechanism, whichwill eventually affect the functionality of the LockJaw and your safety.

Do not over loosenthe adjustment bolt. If it is too loose, the

LockJaw hinge will not close tightly, which will result in a loose joint.

To tighten the adjustment bolt,turn it as indicated by the arrow(clockwise when looking at the bolthead-on)

Adjust the Adjustment Bolt while the frame is closed.

To check the correct tightness of the LockJaw close and open the OCbolt. When the OC bolt closes with a click at the end, the tightness isjust right.

Once you have achieved the correct tightness, close the LockJawby turning the OC bolt 180 counter-clockwise.First open the OC Bolt

The Pivot Bolt

WARNING: Under normaluse, the pivot bolt should

not need adjustment. If the pivotbolt needs adjustment pleasehave it serviced by a certiedbicycle technician.

When the LockJaw is unlocked,the frame can rotate around thepivot bolt. Follow the followinginstructions to adjust (loosen/tighten) the pivot bolt. Sometimesit might be difcult to rotate theframe because the pivot bolt is tootight (one reason for this is thatyou may have accidently affectedthe tightness of the pivot bolt while

you were adjusting the adjustmentbolt).

A 2 mm Allen key and a 6 mm Al-len key are needed to adjust thepivot bolt.

The pivot bolt and its lock screware on the bikes non-chain side.

NOTE:Only turn the pivot bolt in

small increments (e.g. a 1/8 turn)each time otherwise you mightover tighten or over loosen it.

Step 2 (Loosen) - Turn the pivotbolt counter-clockwise to loosen itas indicated by the arrow (6 mmAllen key).

Step 1 - Open the lock screw witha 2 mm Allen key.

Step 2 (Tighten) - Turn the pivotbolt clockwise to tighten it as in-dicated by the arrow (6 mm Allenkey).

Dahon Neos Derailleur


28/32


The original low-prole Dahon Neos derailleur isspecially designed for small wheels. The Neosallows for twice as much ground clearance than aconventional derailleur and the cache technologymeans that the derailleur body lies ush underneaththe chain stays. In this way the derailleur body onlyprojects 12 mm from the chain stays and is muchmore protected than a derailleur which protrudesby up to 40 mm. And the new Neos 2.0 is the nextevolutionary step with upgraded materials andreduced weight.

WARNING: If you are in any way unsure ofhow to make these adjustments yourself,

take your bike to a qualied technician forprofessional adjustment.

Due to its special design the Dahon Neos derailleurs

position differs from that of a conventional derailleur.Compared to a conventional derailleur it is aligned inthe opposite direction, i.e. the adjustment screws andthe wire adjustment bolt are facing forward.

But nevertheless, you can adjust it like any otherderailleur. Please follow the instructions below.

Index Shifting Adjustment

Use the shifter while turning thecrank arm to move the derailleur tothe largest sprocket. Then operateshifter once to move the derailleurto the 2nd-gear sprocket. After thisoperate the shifter just as far asthe extent of play, and then turnthe crank arm.

Best Setting

The best setting is when thecable adjustment bolt is tightened(turned clockwise) until noiseoccurs without the shifter beingoperated, and then loosened(turned counterclockwise) 360degrees from that point.

Operate shifter to change gears,and check that no noise occurs inany of the gear positions.

If shifting to 2nd is notpossible, or shifting to2nd occurs but noiseof the chain contactingthe largest sprocket isheard.

Change to 2ndand turn the screwcounterclockwise untilno noise is heard.

When changing to the3rd gear sprocket.

Turn the cableadjustment boltclockwise to tighten ituntil the chain returns tothe 2nd sprocket.
