The handlebar height suggested in the shop is the highest. If you would prefer to raise the handlebar position, you will need to choose a higher stem.
STOP Before every ride you must check that there is no movement between any of the different assembled parts! Rotation direction Note that 14.5 PSI = 1 BAR and 1 BAR = 1kg/cm2 = 100,000 Pa • Fitting the wheels: Read the section on using quick connectors. • How front and back brakes work: Refer to the chapter on the braking system entitled “checking the brakes”.
A REGULAR MAINTENANCE AND SERVICING Here is an idea of the type of maintenance to carry out on your bicycle, beginning at the date of purchase: how often you perform the maintenance may significantly increase if you use your bicycle intensively in hostile environments (mud, sand, water, etc). 3 months • Full tightening-up of the bicycle. • Tightening and/or alignment of wheels. • Drive train adjustment (if necessary).
B TOOLS REQUIRED 08 09 10 13 14 In order to assemble, adjust and repair your bicycle correctly, you will need to have some basic tools: 15, 14, 13, 10, 9 and 8mm spanners 4mm Torx Flat Phillips Set of Allen key screwdriver screwdriver keys Oilcan These tools are essential for carrying out the different stages of bicycle assembly. You will find them useful for making all the adjustments described in this manual.

2 - Traditional (non quick-release) wheels Removal CLOSED • Open the caliper (see the brakes section). • Undo the wheel nuts using a suitable spanner. • For the front wheel: where applicable, remove the safety washer. • Remove the wheel. Re-assembly • Place the wheel in a central position between the frame dropouts and the fork. • If necessary, replace the safety washer. • Tighten the nuts to the appropriate torque. • Close the caliper (see the brakes section).
G USING QUICK-RELEASE Blocking them maintains the wheels in position inside the frame and fork. In order to prevent it coming loose, it is necessary to turn the adjusting nut (1) such that the closing force of the release lever (2) is at least 12 daN (about 12 Kg). To increase the closing force: turn the adjusting nut clockwise (anticlockwise to reduce the force). Please note: in case of doubt, consult one of our in-shop technicians.
I BRAKING SYSTEM 1 - Using the brakes To slow the bicycle down or stop it: use the back brake first and then lightly and gradually use the front brake. An overly rapid and excessive braking movement may cause the front wheel to jam and cause a dangerous fall. Using disk brakes: After braking, the disks and calipers may become very hot and cause burns in the event of contact. After braking, wait 30 minutes before touching the brake or caliper. Please note: Braking distance increases in wet weather.
STOP Warning 4/ Check that the V-Brake or Cantilever calipers are symmetrical.
IMPORTANT: This safety procedure is difficult, so it is better to contact one of our technical workshops to carry out this type of procedure. Nevertheless, here are a few pointers for users who wish to carry out the procedure themselves. Maintaining disk brakes There should be no grease or oil on disk break pads, it may seriously reduce the efficiency of braking. Before and after each ride, check that there are no leaks in the hydraulic circuit and the wear on brake pads.
K ADJUSTMENT OF TENSION AT DERAILER These procedures are also difficult: we recommend you consult one of our qualified technicians. Frame bolt NB: Problems when changing gear are very often linked to the derailer cable tension; adjusting the derailer travel is much less common.
L ADJUSTING IN-HUB GEAR SHIFTERS (NEXUS SHIMANO-type) Refer to the component guide available on www.btwin.com, for the adjustment of in-hub gear systems. M SETTINGS SINGLE SPEED GEARS (SPECTRO SRAM-type) For single-speed bikes or bikes with integral gear shifters, you will need to have the chain tension checked (it loosens over time). Excessive tension can impair performance and reduce its lifespan (hard pedaling). Insufficient tension can cause the chain to come off frequently.
• A kickstand is designed to support a non-loaded bicycle: never leave a child on a bicycle supported on a kickstand. • There are holes on your frame for attaching a bottle-carrier. If there aren’t, use add-on attachments, fitted using an elastomer strip available in our range of detachable parts. • For rotors and pegs, see the assembly instructions supplied. • You must not add bar-ends, unless the bicycle is sold with them already mounted.
