I’ve been riding it a little over the past 3 months, although it’s been relegated to backup duty since I finished the Lynskey R500 build. I was having loads of issues getting the rear derailleur properly indexed on the Seaboard. On the stand, it seemed to be shifting fine, but shifting under load wasn’t smooth, and the chain skipped around on the larger cogs. I was beginning to think that L-Twoo was a bad choice, but I didn’t want to give up just yet. So I ordered a Shimano 105 11-34 12 speed cassette from a local shop and threw it on. The difference was amazing. Turns out the problem was just that the Goldix cassette was garbage. It’s now shifting just as smoothly as my 105-equipped bikes. So yeah, problem solved, and I think I’ll stick with Shimano cassettes for the foreseeable future.
