Every once in a while we get to build out what I consider to be a Dream Bike. In this case,Frank McGrath from Berkely, CA brought us his Cannondale “Lefty” to set up for all around riding and extreme grade climbing. Here is a list of the components we installed on Frank’s bike:
- Bafang BBS02-750 watt
- DPC-14 Color display
- Gear Sensor
- SRAM EX1 1×8 Speed Long Cage Rear Derailleur
- SRAM XG-899 E-Bike X-Glide Cassette 11-48 8-Speed
- SRAM PC EX1 8 speed Chain 144 Links with PowerLock
- BSBF-1 Stabilizer Bar
Frank has some hills to climb on the mountainous side of Berkeley that are more than 20% grades and with the 11×48 cassette on this bike they truly are a piece of cake. Frank loves to ride with his wife and stay in great shape. He even has a heart rate monitor on his bike and has to be careful to not over do the pedal assist so he can keep his heart rate up.
There was a lesson learned though from this build. Frank was getting an annoying noise in the higher gears of his bike, especially when climbing. After testing, we discovered that the cassette body on his rear wheel was made of aluminum and that it could not take the torque stress of the mid drive. We replaced the aluminum body with a steel body and all the noise has now gone away.
