Butterfly bars are favoured amongst touring cyclists, giving more hand positions while riding than classic drop bars or straight bars. This can be important during long rides to relieve stress on the wrists, arms and shoulders.
Changing bars on a bike is a simple process, requiring some common sense and basic hand tools. There is a need to pay attention to brake and gear cable lengths, where new cables may be necessary to accommodate longer handlebar widths or stem lengths. New handlebar tape will have to be applied, which can be referred to in issue #30 of Cycling Malaysia. After installation, derailleurs will have to be adjusted, the procedure for which can be found in issue #31.
Start by disconnecting all brake and derailleur cables. Slacken the derailleur cables first before loosening the anchor bolt, i.e. change gears to small ring in front and rear.
Loosen the top cap bolt and remove the stem.
Install stem and butterfly bar.
Install brake levers and shifters. Adjust the lever and shifter position to suit.
Wrap the handlebars and route the cables.
Reconnect the brake and gear cables, and adjust for proper operation as per Cycling Malaysia’s Maintenance guide in issue 31
Finish off by taking the bike for a test ride and adjusting the butterfly bar position. Further fine tuning may be necessary as your hands get used to the new riding position, so make sure you carry a suitable allen key or multi tool with you for further rides.
