8 CA­BLE PRE-STRETCH­ING STEPS

Canadian Cycling Magazine - - MAINTENANCE -

With the han­dle­bars un­wrapped and hous­ing un­se­cured to the bars, shift to the largest cog in the back and the large chain­ring in the front.

For an ex­ter­nally ca­bled bike, pull on the ca­bles lightly, one at a time. Start at the down tube, and then at the right chain­stay for the rear de­railleur. Do not pull too hard. If you do, you risk break­ing ca­ble stops or frame in­serts. If the bike is in­ter­nally ca­bled, the process can be bit more dif­fi­cult as there is no ex­posed ca­ble to grab a hold of. Shift the rear de­railleur to one of the mid­dle cogs. Hold the de­railleur at one gear with your left hand, while si­mul­ta­ne­ously cre­at­ing ten­sion with the cor­re­spond­ing shift lever. Do this ever so gently un­til you just about feel the shift lever click up to the next po­si­tion. The same can be done with the front de­railleur.

Shift the rear de­railleur to the smallest cog and the front de­railleur to the smallest chain­ring.

Turn all bar­rel ad­justers in. Re­set the ca­bles by loos­en­ing an­chor bolts and pulling out any slack be­fore re-torque­ing them.

Do your fi­nal tun­ing. Se­cure the hous­ing to the han­dle­bars (on a road bike) and wrap the bars.

For your brakes, squeeze them firmly at least five times to seat ev­ery­thing, and then read­just.

Once ev­ery­thing is tuned and the bike is on a stand, go through all the gears rather quickly and with more force than you’d nor­mally use when rid­ing. This step pro­vides ex­tra in­sur­ance that you’ve re­moved all the slack out of the sys­tem. Check your work again to see if you need to make any further ad­just­ments.

Go for ate stride. Run through all the gears to en­sure ev­ery­things hi ft swell. If you per­form the above to aT, I guar­an­tee you won’t need a fol­lowup ad­just­ment af­ter your first ride.
