I had 2 examples of each of the Salsa Delgado 29ers rims: the normal rim brake CX version still sold, the retired Disc and retired Disc Race. This week, I had to toss the last two examples, the CX rims after finding cracks next to the eyelets.
Many people seem to trash the reputation of these rims on-line, but just like everything on-line, the crabby people are the most visible. Every one of these rims have failed me, however, I am satisfied with them. They all lasted a long time, did not cost much, and performed as expected. First the Disc 29er ones. I bought them built with XT disc hubs for like $125 around 2006. The rims developed an annoying rattle. Salsa recalled them and I got brand new rims and Salsa covered the labor and new spokes to rebuild them. I then ran those rims for years on a 2005 Gary Fisher Rig until I gave them away to Mt. Rainer Bike Co-Op
The Disc Race 29ers were built by a skillful builder with XTR disc hubs. They were great! Light and caused me no troubles until, my lame ass technique taco’ed the front in the 2009 SM100. It may have happened with any wheel, but probably not with a heavier & tougher rim. The rear then broke at the weld about a month later, regardless, I got three years out of those racey rims. Totally ok with me.
Lastly the two CX versions. They have been beat and beat on a series of CX and commuter bikes. The front one’s brake track is so worn that I need to retire it. The rear (pictured) developed the cracks between the eyelets. This is reported by many, but after 8 years and how it was used it is totally ok with me.
