Apologies in advance for the flood of newbie technical questions but this was brought to my attention on the Bike gallery thread.
This is my new bike...
Though apparently the chain is too short as the RD angle is pulled too far forward. I've double checked the bike since then and the RD appears only to be pulled this far forward on the larger chain ring, when on the big cogs Normally it does look instead like this on the small chain ring:
cause a greater wear on the jockey wheels, cassette and chain also greater stress on the mechanism itself as it is already nearly fully extended. "
It is a new 105 long cage derailer and funnily enough the LBS actually adjusted all my gears as I was having trouble with the FD...but they didn't say anything about it. Currently gears are running very smoothly, though I am concerned if there is going to be increased wear.
I sized the chain according to the Largest Cog and Largest Chainring Method on the Park Tools Website
So I guess the question is:
1) Is this a problem even if it happens only on some of the gears?
2) What can I do to fix it? Won't putting links back into the chain damage it by deforming the pins? (The LBS told me to use the chain breaker sparingly, thus the reason for the powerlink in the first place)
3) Why didn't the LBS pick this up when they were adjusting the gears?
Thanks a heap in advance guys
