First Look: Pacenti TL28 Lightweight 26er Mountain Bike Rim

Kirk Pacenti (the man behind the 650B push and the open standard for freehub bodies) recently announced that he will be bringing new mountain bike rims to market starting in November of this year.

I know what you are thinking…more rims? What makes these different than everything else that is already on the market?

Well…outside of being available in 26, 650b and 29er sizes, the new TL28 series of rims extends the wider and lighter trend to the next level. As you can see by the scale, these Pacenti TL28 26er rims weigh in at 360g (Feedback Alpine Scale) while having an inside width of 28mm and are tubeless friendly. What does this mean in comparison to the competition? If you are familiar with the Stans rims (some of our favorites here at Bike198), that means you get a rim that is as light as the Crest (370g vs. 360g) and wider than the much heavier Flow (23mm vs. 22.6mm).

Pacenti TL28 26er Rim

In talking with Kirk before these rims were sent in for review, the TL28 rims are designed to be trail ready rims that are not meant for drops and hucks. Basically, if you are the kind of rider that looks for a wide contact patch on your 5.5″ rear travel mountain bike or under but you are also concerned about weight, this might be the perfect rim for you as long as your primary riding keeps away from stunts.

This set of rims are on their way to Chad at Red Barn Bicycles to get built up and ready for review. We will keep you guys updated as this process gets up and going. Kirk is going to have these rims available for purchase starting in November 2011.

The image below shows an side width of 29/32″ which equals 23mm.

    What do the 29″ rims weigh?

    What is the price of the 29ers?

    How long is the warranty?

    How do these compare weight-wise and performance-wise with the Easton and Roval 29ers?

    29er TL28 Weight: 438g
    29er TL28 Price: $85.00
    Warranty: No listed but standard is a year typically
    Weight comparison: Lighter but, Easton and Specialized do not sell their rims separately so a direct comparison is difficult.
    Performance comparison: We’ll see when they get in built up on hubs. They will be wider and lighter, but we will have to see how that does on the trail.

    Don’t expect them to be so light. Mines came at 392g and 393g
    Good for me as they are going to be used for enduro, and I was interested in the 28mm, sub400g and eyelets
    but not good news for weight wenies

    Ours weighed out to 360g as mentioned in the article. I wonder why you saw such a difference.
