Newbie - First road bike - grinding noise/ feel

[sebbie74]

Hello all,

I just purchased my first road bike (recent love for the sport), a Marin Argenta that was received 90% assembled. I completed the assembly then took it to my LBS for a tune up. After the tune up, I can notice a grinding noise/ feel while pedaling with high gears (cogs #1-2-3 I think that is the largest diam. ones, sorry I don't know all the proper terminology yet) and front wheelring is any (I have triple crankset).

I took the bike back to my LBS explaining thT being a brand new bike, I thought it should feel smoothest while pedaling, at any gear selection, they attempted to 'fine' tune the derailleurs (rear mainly).

Eventually they told me that being a new bike it was normal to have that grinding noise/ feel in high gears and that I needed to go thru a break in period with my bike.

I am a bit surprised by that comment but I suppose it can make sense. Could any experience rider share his/her thoughts about the LBS comment?


Very much appreciated and thank you for reading my first post!
