Velocity releases A23 wheelset and Race Hubs
(Grand Rapids, MI) Velocity is proud to release their A23 wheelset and Race Hubs. Both products are a continuation of their belief in developing and producing wheels and rims that are the best to ride with. The A23 wheelset partners the popular A23 rim with Velocity’s new proprietary Race Hubs. The rear hub is designed with a 51% larger drive side flange height providing precise tension, allowing for a symmetric wheel that is stronger and stiffer than a rim laced to a ‘traditional’ flanged hub, optimizing power transfer. Using a 23mm wide tire with the A23, riders maximize tubular ride qualities while retaining the convenience of a clincher; increased cornering abilities especially at high speeds without sacrificing rolling resistance makes the A23 wheelset THE set for crits, ‘cross and road races!
Specifications on the A23 Wheelset:
Rim – 426 grams
Pro Build* – 1400 grams
*Built 20/24 with Sapim CX-Ray spokes and alloy nipples
Specifications on the Race Hub:
Front Hub – 78 grams – available in 20, 24 and 28 hole drillings
Rear Hub – 256 grams – available in 24, 28 and 32 hole drillings

We make no qualms about keeping our ear to the ground, listening to the cries of cyclists then pushing forward to produce a product that meets those desires. Throughout our 18 year history we've developed rims to suit the needs of riders and in our most recent past with the B43 to the Chukker, the Blunt to the P35, the A23 to most recently the Major Tom, each of these rims have been sought after by riders in each discipline they were designed for. The beautiful thing about all of our rims, there is an amazing amount of cross over to other segments that has occurred with each of these.
roud to offer you another option for your fixed gear freestyle needs. The 700c Psycho joins the Deep V, B43, and Chukker as a rim of choice for fgfs. The fact of the matter is wider rims hold wide tires better than skinny rims. Some of our smoother riders like Torey, Wonka, and Tom La Marche have been using our P35 wheels as a lightweight solution to their tire-rolling woes. The Psycho, a 31.5mm wide beefcake, is a much sturdier option for those seeking a rim that can take a serious beating.Michael Chacon, Jamil Gray TEASER from Michael Chacon on Vimeo.

The P-35 rim, introduced last year, was the second widely available rim in the 30 plus millimeter range. How would it hold up to regular mountain biking. How would it play with your tires? Is it a worthy choice for average trail riding 29″er freaks? These are the questions I had going into this review. Now, after several months of riding everything from packed snow machine trails to swampy, muddy track, to dry, rooty single track, here are my final observations on these rims/wheels. Also, as a bonus, I’ll cover the new Velocity rim tape that turns any set of P-35’s to tubeless compatible wheels. If you have missed the last Mid-Term Report, you can click this link to read that.

Wide Track: The P-35’s claim to fame is its reasonable weight plus its width. The width spreads out a 29″er tire, and is also said to give the tire better support. One thing needs to be considered though when looking at a 35mm wide rim. Your tires may actually end up being worse performers on a P-35 than they are on narrower rims. Why? It is because the tread area on some tires actually flattens out when the beads are spaced further apart. This flattening of the tread area may “close up” the tread, making your tires skittish, or loose. Generally, I would suggest using wider tires, over 2.3″, on this class rim due to this phenomenon, but experimentation is always good.
The wider rims also may cause issues with tire clearance in some frames. If you set these up with 2.4″ers, it will certainly cause you to use up most, if not all, your chain stay clearance. Many older 29″er frames were not made with these rims and 2.4″ tires in mind. For instance, the Ardents on the P-35’s I had were nearly 62mm wide at the casing. That sort of casing width isn’t going to leave a lot of “breathing room” in a lot of frames out there!
The Wheel Set: Now for a word on the wheels specifically, which are built on Velocity branded hubs. These wheels were trouble free during the entire testing period. They stayed true, and to my surprise, the wheels did not develop fouled bearings despite my best efforts to get them contaminated. The bearings are very smooth to this day, and I wouldn’t hesitate to have Velocity build me a set again. The tensions were great, and I have no complaints on the build. The only thing I would suggest is for Velocity U.S.A. to consider developing a front hub that is convertible from 9mm QR to 15QR, to 20mm through axle. This would make buying a hub from Velocity much more appealing, and make the hub a versatile one that could go from bike to bike with a quick end cap change.
All you need to set up a pair of P-35’s to be tubeless compatible.
Velocity Velotape: The Velotape came out after we received the wheel set, so Velocity sent the Velotape out after our Mid-Term Update. I set up the rims after removing the tire and make shift rim strip I used previously. Let me tell you, the Velotape is a far more elegant solution! I cleaned the inner rim cavity thoroughly, and then I was all set.
It is important to slightly stretch the tape as you apply it to make sure you minimize any air pockets after application. (It is kind of like applying a decal, if that makes sense.) The inner cavity of the P-35 is “U” shaped, so following up with some pressure from your index finger where the tape meets the rim is advisable. (See image above)
After overlapping the tape at the rim seam, according to the instructions, you pierce a hole at the valve drilling to allow installation of the supplied valve stem. (Make sure you pierce the valve stem drilling and not a spoke hole!)
When inserting the stem, make sure it is seated all the way in, as shown here.
The valve stem nut comes with a supplied washer that goes against the rim as shown. Then you are ready to install a tire, add sealant, and air it up! I used the Ardent 2.4″er again, and the process was seamless. So far, the system has proven very trail worthy. (By the way, the valve stem does have a removable core.)
Conclusions: The Velocity P-35 rim succeeds in that it is a trail worthy rim at a reasonable weight and price. It comes in many colors, and is easily found from many on-line and local bike shops. The new Velotape adds extra value to these rims, but it is an extra purchase on top of the rims, so be aware of that. The rims seem to be of average stiffness and would be best suited to XC to light AM uses. Front single speed applications, and anywhere a rider sees that a wider footprint on a 29″er would be advantageous would be places to look at using a P-35 rim. The weight is very reasonable for the width, but even so, this isn’t an XC racers rim. This rim is for the everyday 29″er rider that wants to maximize the performance of the wider tires on the market for 29′ers.
The wheel build gets an A+. I had zero issues with it, and the tensions were good and remained so during the entire test. The hubs were also a highlight, and for the money, they were a great value. I didn’t necessarily care for the thread on free wheel compatibility or the fact that the 20mm through axle is not convertible to other standards now available. If you don’t want to fuss with building up a set of P-35’s, have your bike shop do it through Velocity U.S.A. and they will be a great wheel set, if this one we tested is anything to go by. They do have standard geared cassette hubs for geared use which can be set up with spacers for single speed use.
The Velotape is an easy to apply solution to get the P-35’s going as a tubeless wheel set. I had no issues with setting up the tires I was using as tubeless on this system and the valve stems and tape seem to be top notch quality stuff. I’ve seen much worse!
Finally, the Velocity P-35 is a welcomed addition to the choices for a 29″er rider in terms of rims and wheels. The colors available are unmatched by other companies, the quality is consistent, and the rims themselves are workhorse pieces that should serve most riders well, save chunk riders and anyone pushing the limits of 29″er wheels. These folks should look elsewhere for rims, but for a wide swath of the 29″er riding public that is wanting a wide footprint for their rubber, the P-35 rim from Velocity U.S.A. should be a serious consideration.
Note: Twenty Nine Inches received this wheel set at no charge for test and review. We are not being bribed or paid for the review here and we will strive to give our honest opinions throughout.

Never ones to be satisfied with their own success, Velocity has just released the Major Tom
tubular rim- to the rejoicing of ‘cross racers everywhere. Like the Velocity A23 and the HED series of 23mm rims, the Major Tom rim brings the advantages of a 23mm rim to the tubular market. Having a 23mm wide rim allows for better tire performance, gives a larger contact surface for gluing tires, and adds strength without adding weight (432g advertised weight). Gluing wide cyclocross tubulars onto narrow rims can often be a challenge, and questioning the bond between the tire and rim is often something that enters your mind as you’re railing a corner at top speed during a race. The Major Tom not only gives a wider contact surface, but it also features a seam relief channel down the center, to help with consistent tire placement.
Additionally, Velocity listened to feedback from ‘cross racers and increased the height of the brake track to 11mm, making it easier for you to switch from your everyday wheels to your race wheels without so much messing around with your brake pad placement. Like the A23, the Major Tom shares a similar semi-aero profile that gives additional strength without adding weight.
Just in time for the season:
But don’t think that this rim is only confined to cyclocross- like the Velocity/HED 23mm predecessors, the Major Tom would help achieve better performance for road tires as well. We mounted a Vittoria Pave 24mm tire and it looked like the two were meant to be together.
Optimized:
We have a few of these rims that we’re building up for our own use right now, and we should have production wheels with Ultegra hubs and DT Swiss Competition spokes ready in the next few weeks- just in time for ‘cross season.
It's been a busy week here at Velocity. Lots of orders to fill topped with Interbike on the horizon, blog posts have been put to side. I was able to get one of our professional wheel builders Rachel to do a quick write up on her custom Seven.
1st tee, the Velocity crew.
