• What are the benefits of moving from say a 60mm rear rim. To a 88mm one?

    Trying to decide between the two pictured. It'd be With a 60mm front, and my only road wheelset. Which I'd use for mountain Climbs, road races, and tri's.

    To be honest I tempted just to stick to 60/60, Seems to be a good middle ground. But if there's a real benefit to the 88 for only around 40g of weight penalty. I could be swayed.

    There's only about 2W at 50km/h between a 404 and and 808 on the front, it will be even less on the rear.

    I wouldn't even go 60/60 on something which was my only road wheel, 60mm can be a handful as front wheel if it's windy.

  • Depends on the bike. The dude from HED said with superbikes that shield the rear, rolling resistance is more important to consider than aero. Wheel aero is 70/30 front/rear whereas rolling resistance is 70/30 rear/front. So, my answer is obviously, "dunno" but probably "not much".
