Hey Tom just wanted to report that my friend that has the Rohloff on his Ultra powered bike is now having issues with it slipping intermittently when in gear.
Not necessarily when under max load like when climbing but also on the flats just cruising along.
We were’t sure if it was the hub or motor so we swapped out the motor to a spare I had and it still had the same issue so we knew it was hub related.
Chainring, chain, rear cog, and tensioner are all good so…
We checked the shifter cables and they were spot on but my buddy wanted to replace those to make sure just in case and the problem is still there.
He also ordered some new pawl springs to see if that helps and when they get here we’ll pop them in and see if it makes a difference or not.
He talked to a guy a cycle monkey and he said the hub wasn’t rated for the 160nm of torque that the Ultra provides.
To be fair my buddy rides 99% in mode 3 and is not shy with his throttle so that might be a contributor as well.
It’s out of warrenty and from what he can find out having it serviced closest to us is on the east coast and about a month turnaround.
So it looks like we’ll be stealing some parts from a spare bike he has to set it up with a derailer rear end until he can sort this all out.
Just wanted to post up on his issue.
Will update when I know more.
