Depends on the subscription length. Like if I was planning to do a major overhaul on my bike or get a new frame, i'd consider a year subscription or something because the savings would probably offset the service fee. But definitely couldn't see myself paying for that service year after year.
Yes I would $240 a year cost My bike goes thru more than $500 a year in parts assuming I would get 50% off I'm still coming out ahead. Also assuming shop is geared towards my type of riding and has good accounts for a variety of parts.
