SchwalbeG-One Speed Race Guard 650b Tire(Return to Product Page)

I installed the 1.2" (30mm) version on my misses, 5 foot nothing, 100 lbs of muscle, 3XS Canyon Endurace. For the price, they are a steal, compared to the current offering of 650B road tires. They have given her more confidence on rides where, some dirt sections are necessary, and/or pavement is very poor. Based on her weight, she can also run low pressures, which helps with my previous statement. I'd recommend them for anyone who is gravel curious, but only has a road bike.

I got the 2" variant with "bronze" sidewall and it is as advertised. Mounted to an Enve G27 it's exactly 2" wide. Bronze sidewall is darker than typical "tan" sidewalls which was expected per the photo.

What I do love is that this is slightly lighter than my old WTB Byways and rolls much faster (FYI apparently Byways are some of the slowest tires and IMO the quality has changed so I'd steer clear of).

First impression is "love 'em" so we'll see how they hold up!

Been running these on my daily commute bike for a year, set up tubeless. At 30 psi they provide great damping for rough streets and roll quickly. A deep puncture in the middle of the tread sealed up will with sealant fluid and has not been losing pressure for weeks since. Holding strong after thousands of rough miles on road and cutting across fields, hucked curbs, and gravel trails. Best tire I've ever used on a pavement bike.

The advertised 2" size is off more than any tire I've ever seen. I mounted one tubeless to a 21mm internal width rim, and it measured at 1.4" at ~40psi. Returned.

*Addendum from Bike Tires Direct* The inner width of your rim will absolutely have an effect on the outer width of any tire. If the rim is very narrow, the final width of the tire will not be the width of what is advertised. Bike Tires Direct staff.

How can you review them if you can't mount them ?

Schwalbe 'TubeLess Easy' = not so much.

Who hasn't ripped a tubeless tire & needed to stuff a tube into them ? Very, very difficult beads to deal with.

((Fyi: WTB 21mm rim))
