I recently purchased my first Rocky Mountain bike and Element 30. Overall I have to say that it was a good purchase. The one issue I am having is ghost shifting and not shifting correctly. I have had to take the bike back to the local shop just about everytime I ride to get it adjusted because it will not shift correctly. I have given up on the shop where I purchased the bike due to their inability to fix the issue. The other local shop that I use has gone over everything and can not find anything wrong with the bike but again it will not shift correctly. Any suggestions would be very helpful.
