• SC501 has a 42.7mm chainline, Pompino says it needs 42. Dead soon? I had not idea what chainline was until I'd been riding for ages.

    Not from that cause. Even if your hub/sprocket combo is bang on 42.0mm, I'd be a bit surprised if a Pompino was tracked to better than ±0.5mm.

    Will have to roll with that chainguard like a boss.
