If you have Zipp 202 NSW, 353 NSW, or 303 SW, you just got an upgrade. Zipp just announced that those wheels have updated tire clearance. So if youre looking for a wheelset that can do road and gravel, youll already be riding them.Zipp 202 NSW: Now up to 35mmThe 202 NSW is Zipps lightest wheelset, coming in at under 1,100g. Its still aimed squarely at climbing and road racing. The new 35mm maximum tire width gives it a little more room outside traditional road use. Plus, if youre a cyclocross fan, they would make an excellent (and super expensive) race day wheelset.Zipp 353 NSW: Now up to 49mmThe 353 NSW is now cleared for tires up to 49mm. With its undulating 35/40mm-deep carbon rim, the 353 NSW uses a 25mm internal width. The 353 NSW was still optimized around a 30mm road tire. The wider 49mm limit makes the 353 NSW much more useful for all-road and gravel setups.Zipp 303 SW: Now up to 55mmThe 303 SW gets the widest range of the three, with compatibility now extending to 55mm tires. The 40mm-deep rim is optimized for 30 to 35mm tires, but the new maximum gives riders far more room for light gravel to full-on adventure.Zipp says the 303 SWs revised carbon layup gives it nearly 10% more impact strength, while the rim profile helps protect the tire during harder impacts.Upgrade Without Purchase The best part is that nothing needs replacing, and if you have any of these wheels, youve just upgraded. For riders moving between road, cyclocross, all-road, and gravel, this is great news.
