I just recently purchased a new 2019 Orbea Gain M30 (size Medium) on eBay for $2,900 all in. I feel pretty good about the price and am looking at possible carbon wheelset and cockpit updates. Whether it's actually worth the $$$ to shave roughly .5kg / 1 lb of weight and to improve the feel, who knows. That's not really what I'm asking to be debated though.
I did a full Syncros carbon wheelset and cockpit upgrade to my Diamondback Century 6c last year and it was well worth it, but I also found a guy locally on Craigslist dumping the whole Syncros setup for $750 all new off his bike so it was a no-brainer to trade out my aluminum parts for the beautiful carbon. The weight savings were awesome getting me from 19lbs to slightly below 18lbs and the performance is noticeable.
Before I keep rambling on, I guess the questions that I have are this regarding my Gain M30:
1. Has anybody changed out the Aluminum wheelset and/or cockpit to full carbon, if so has it been worth the money to you?
2. I see that the M10 comes with the Mavic Carbon wheelset. Can other carbon wheels be used on the M30, or is the Mavic carbon the only option due to the Ebike Hub Motor?
