I got a new bike a month and half ago i have ridden it hard almost everyday, 25 miles a day for training , and today i noticed that the cable tension on the shifters rear derailleur and front derailleur cables are a bit loose ,, the shifters feel a bit less snappy and softish or not enough cable tension , the rear derailleur feels and sounds like it needs a slight adjustment and the chain on the front derailleur is rubbing a bit more than it was before. i guess my question is is it normal for cable tension to loosen up on a new bike ?? have you guys ever lost some cable tension on your new bike ?? is it okay to ride like that ??
