Last year, as GT was developing their new Grade gravel road bike (more on the bike coming soon), they went to Stan’s NoTubes for a high end, tubeless rim to go on the top models.
The result is the new NoTubes Grail gravel road bike rim. Technically, it’s just a wider, disc-specific road rim, but it’s built durable enough to handle off pavement escapades. Rim profile is wider than their current offerings in that category, namely the Iron Cross, and it can handle a heck of a lot more pressure.
Width is a hair over 20mm internal, and just over 24mm external with a nice rounded profile. They’ll offer it in 24, 28 and 32 hole drillings and as complete wheels in Team and Comp specs. The bead can hold up to about 125psi, making it perfectly capable as a wide road bike rim for things like the Hutchinson Fusion and Sector, etc. Look for more tech details this week, and a few more pics are after the break…
Retail will be $105 for the rim, and Team and Comp wheels are $695 and $645 respectively. Main differences are 24/28 lacing and stainless bearings on Team and 32/32 lacing and standard steel bearings on Comp.
