Anyone know the diameter of the square-taper BB is for the Rover? I guess I need the diameter, but also the width of the BB. I'm not sure I need to replace it, but, I'm hearing a transient clicking sound from the front of the trike, and it's been getting louder, more 'sustained'. It started as a single click, then, went to two clicks, now it's up to 4 or 5... It sounds like ball-bearings clicking against each other.
It only occurs when I'm pedaling forward, never in reverse, and of course, when not pedaling. I've tried to make sure the sound is coming from the BB... but, when off the trike, no matter what gear the SA is in, pedaling by hand fails to make the sound. I've tried pressing down on the pedals when spinning them, trying to 'emulate' the pressure of my feet on them, but, still, no clicking sound.
If I do end up needing to replace the BB, wondering if it's cheaper for me to do it - having to purchase the specific tools needed to remove the old unit, or take it to my local lbs.
I purchased the Rover used, and have put about a 1000 miles on it in the last 8 months or so. Most riding is hilly, lots of ups and downs... sometimes, quite steep.
