I recently bought a Kona Process 153 (first real mtb!). I’ve not done much in the way of modifying as it is such a good bike straight from the shop. I did however fit a bash guard with integrated chain tensioner and guide. I fit it as per instructions and set it up in the same manner. I did however encounter a problem after fitting.
I took it out for a ride up and down the front street to check for any problems. Luckily I did as the chain came off the cassette on the smallest gear (sadly scratched my frame). I managed to get it back on and ride home. I took the tensioner off as I was planning on riding some single track the following day and didn’t want to run into the same problem on the trail but ended up having to take my bike back to the shop as the gears stopped shifting properly and it had developed some excess chain noise.
Now it’s shifting as it should again and I want to get the tensioner back on. My question is thus:
This particular chain tensioner works by adding a jokey wheel at the bottom of the chain ring. When installed do I need to add a new chain with extra length to account for the tensioner and/or do I need to adjust the rear derailleur or cable tensions?
