29+ AKA Midfat AKA 29×3 AKA Krampus platform

29+ will be the next bicycle wheel platform I explore.

“The new 29+ size refers to 29in tires that are 3in wide and offer some of the benefits of fat bikes in more manageable package for general mountain bike use.” Josh Patterson

Surly Bicycles debuted this new “midfat” platform that employs the 700c (29er) diameter rims with a greater width of 30-50mm compared to typical 17-25mm wide “regular” rims that fit 2.0-2.5 inch wide 29er tires back in 2012. We are just starting to see lots of talk about this platform as custom bike builders like Jeff Jones have released their own 29+ bike models. This extra width allows the 29×3.0 inch tires, which Surly first showcased in the Knard model to fit on these wider rims.  Surly designed a new frameset which was later released as a complete bike which they dubbed the “Krampus”.

Slight sidebar:

Krampus definition is best explained in this video from the Tonight Show with Jimmy Fallon when “Elf on the Shelf” is compared with the Krampus:

There is a Facebook group that you can join or just lurk around on to view all types of discussions, frames, forks, tires, and wheels that support this new platform:

It appears that my trusty Salsa El Mariachi that I have discussed so frequently on this site can fit a 29×3.0 Surly Knard tire if mounted to a rim no larger than 35mm wide in the Salsa Fargo fork I am running up front! The frame can only fit a 2.4 inch tire on the rear, so I will likely just keep it as a “regular” 29er setup on the back for now, but there is promise of a 27.5+ setup that should fit a 2.8 inch rear tire back there. Still unsure of the 27.5+ addition to my El Mariachi, but  I will be pursuing this 29+ setup on the front sometime in the next few months so stay tuned!

Thanks for reading!
