Subj: R10-h chain kept jumping off the front chain - Purchased new 2 days ago
I am new to posting. I hope someone can give me a tip. We just bought a new bike from RMartin (R10) and the front chain keeps "derailing". The chain a low gears appears to be being onto the front crank. Upon searching I found others on this site with a similar issue. I have left two phone messages (1 service and 1 sales) and two emails for guidance with RMartin but no response back. I only have 7 days to figure out if this is a defect or normal issue. I really want to keep this and buy a 2nd one. I will try to post two photos.
Thank you for any suggestions, William
