Am researching 27.5 rims for a buildout running SRAM XX1. Looking for eval of Velocity Blunt (in particular) and other rims I should research. My body weight = 135 lbs. and frame is Pivot Mach 6.

Phread,

If you're building a Mach 6, you should check out the Pacenti TL28 or Pacenti DL31

The Blunts have two widths, and if I recall, could get you a wider rim for same or less weight than the Pacenti rims. I believe the Pacenti rims are advertised as DH tough so any criticism of weight should keep that in mind. Those (Pacenti, Velocity), Stand Flow, and the LB plastic (carbon) rims have captured my attention.

At 150 lbs I've never been a rim trasher like some I know. Your 135 should have you in that category.

I have back-to-back experience with the TL 28 and Blunt rims. I would easily choose the TL28 between the two. TL28 built up surprisingly stiff, definitely better than the blunt, and at about the same weight. TL28 has spoke eyelets, Blunt does not.

That said, both rims are a little on the soft side. I have put a lot of good dings in my TL28 rear wheel, but it's on a hardtail that I ride fairly aggressively. I'm about 165 lbs in full kit. I have been able to bend all the dents back out with no issue. The TL28 on the front is still in great shape.

Generally, hard to go wrong with Pacenti products. Thanks Kirk!

Blunt 35 27.5”

Formerly called the P35.

The '35' part is a reference to its astounding width, which gives any wheel built with it a larger footprint, and so, more traction. Very useful for cross-country and all-mountain riders who are looking for lateral stiffness without so much weight

I am on my second set(1st set was 26ers) of TL28's and they are buy far the best rims I have owned. I am 240 geared up and rode them on a Foes XCT and now on a KHS 650B hardtail and ride pretty aggressive. Both pair are stiff and light and will do very well under a rider who weighs 100 lbs less than I.

Blunts are fine... but Kirk's rims are much nicer and better for tubeless.

EDIT: I believe the Blunts have been redesigned since I bought my last pair, and now have a much more tubeless friendly cross section than the 650b 28mm wide versions that I bought a few years ago that relied on a split tube ghetto setup for reliable tubeless operation....new ones appear totally different, so....grain of salt.

I'm at a (shameful) 180lbs these days and run our Blunt 35's in a 28h 2x lacing pattern. At your size, you should honestly have no real trouble running any lightweight cross country rim out there, down to our Blunt SL. I will say that I prefer the the width of the Blunt/Blunt 35 myself.

I bought a set of Blunts for my Mach 6, but ended up with carbon rims. Nothing wrong with Blunts. I just wanted to try carbon. I'm 180+gear and I have no doubt they would hold up fine on rocky/rooty AM terrain where I live.

Prior to the Mach 6 my GF and I ran Velocity Blunt 35s on our Nomads for several years of combined riding. No issues. Setup tubeless fine. Never burped or lost air faster than tubed tire.

I'd have no issues using those rims. In fact I kept mine and they are likely to go on another build.

I'm loving m7 27.5 Blunts; the only tubeless ready rims with "normal" tires that aired up with a floor pump and stayed aired up.
