Hi Guys,
So after doing my own bike with a Bafang mid mount kit its time to start my wifes conversion with an NCCycles rear hub kit. Kit bought from UK supplier but its a Chinese kit.
My wifes bike is a Specialized Rockhopper Expert which she has had for about 10 years.
Did a bit of research and watched a few Youtube videos of how the kit fits and thought yep , not too difficult by the look of it..!
Err no.
Started with the swap over of the rear wheel. No probs until I try to tighten up the chainset supplied with the new kit, my tool wont go over the new axle as my socket has a centre spline to align it on the chainset (when the axle is removed ,which doesn't come out on new hub)so I had to order a new tool without a spline in the middle. Got one and tightened up the new chainset on the new hub no problem.
Next swap the brake disc over , and thread lock it as advised. Done. Offer the wheel into the rear forks and it is a bit tight in there. Especially with the washers etc that I needed to ensure chainset is not up against the forks. After much toing and froing I got the wheel axle in position. Now I find the brake caliper rubs the hub motor. I was advised the disc spacer was not required, ummmm, on my project it is, so out with the wheel again. Only now ive tightened the disc bolts too much and the thread lock has worked a treat. Got 5 bolts out and had to grind the head off the last one. Then use an extractor on the remaining part of he last bolt which fortunately worked. Anyway reassembled it all with and more time spent getting wheel back in place. Disc is now clear of the hub. I did not want to file the drop outs which would have made life easier as they need to be a tight fit around the axle hence why it took me longer than I wanted to get the axle in position.
Spent some time aligning the torque arm to utilise a 5mm tapped hole in the frame and had to drill a hole in the torque arm to match the frame. Another time consuming job but its all good and secure now .
Ensured the wheel nuts were torqued to specification and all ready for next stage of the instalment.
I will post up some pics so far.
Regards
Rob.
