For early adopters of road tubeless, there has been one common request: larger tires. Thanks to their puncture resistance and sealing abilities, road tubeless seems like an excellent choice for gravel and dirt roads if there were simply tires suited for the purpose. Hutchinson looks to have answered that request with their long awaited Secteur 28. Originally created as the Intensive 28, the new Secteur promises 28mm of ride comfort, traction, and durability.

Does it deliver? Find out, next.


Designed more as a fat road tire, the Secteur has a completely smooth center section with knurled shoulders. You’ll never lean far enough over on the road for the shoulders to touch, but if you’re riding off road and the tires dig in a bit there may be some added traction from the texture.

As far as  real world sizing is concerned, mounted to 23mm wide Bontrager TLR rims the Secteur 28 measured only 27.3mm even after fully stretched (both front and rear). Considering the Bontrager R3 25mm tires measured 25.9mm, the smaller than advertised sizing may leave some hoping for large tires disappointed. On the plus side, the tires are still pretty light for even a 27mm tire at 285g.

The good news is that once seated the tires hold air incredibly well with Hutchinson’s Protect’Air Max. It’s worth noting that the fluid installation method mentioned in the last post with the ketchup-style vavle works surprisingly well. No need for cups, straws, or tools, just open the valve, push the bottle over the valve stem, and squeeze. No mess, no fuss. To inflate the tires, you will need an air compressor and some patience to seat the tires at least in my experience with the Bontrager rims (the Bontrager tires were much easier to mount on the same rims).

As for tire clearance, the Secteur 28s were mounted to a Raleight Revenio 4.0 we have in for review. Installation through the Ultegra brakes was simple with the brakes opening wide enough to not have to force the tire through the pads. Clearance in the frame is adequate, though on a muddy mulched trail that linked two sections of pavement I was riding, I was able to pick up enough crap that the tires completely jammed. In this case the smaller width might actually be beneficial because if they were any bigger they probably wouldn’t fit in most road frames.

Overall, as the current leader in fat road tubeless the Hutchinson Secteur 28 is great choice for riders looking for something bigger than a 25. Ride quality on the Secteurs isn’t the best on the market, but at the 80-90 psi sweet spot (80 for me at 150 lbs) the tire rides pretty comfortably and feels fast for its size.


  1. Love, love, love this tire! I’m using it mostly for paved road riding with the occasional ride through dirt and gravel roads. I’m a big guy at about 215lbs. Running em at about 90PSI, these run great form me. They’re just as fast as the Fusion 3s I was running previously and handle surprisingly very well… maybe even a little better than the F3s. In fact, I’d say these feel and ride better for me than the F3s in every way.

  2. I have been trying to get in touch with Hutchinson for months for a de-lamination issue on the Atom tubeless. They do not have any way other than email to contact them and they never reply to emails. I will no longer stock any tire from a company who does not support them. (I can still buy them from a distributor all day long) This could be the best tire ever, but if there is a problem your SOL. Buyer beware.

  3. Dane, Thanks for sharing that. I have a pair of Intensive 25’s that I really like, but knowing that the manufacturer doesn’t stand behind their product will weigh into my future purchase decisions.

  4. I’ve ridden a selection of Hutchinson road tubeless, Atoms, Intensive 25’s, Fusion 3’s…
    I worn all but one out before I had a flat. For me the F3 is a great all around tire.
    I train on them, race the Tues Worlds, and enjoy passing mtn bikers on the trails in Santa Cruz. Can’t wait to try the new fatties. I’ve had excellent customer service from Hutchinson so I wonder at the context of the above comment to the contrary. Company email often gets overloaded, maybe contacting the actual rep in your area would get better, more personal results.

  5. Through my local rep and/or direct contact our east coast shop has had no issues contacting Hutchinson and resolving potential warranty or information requests. Dane – If you are trying to contact Hutchinson France, that is the incorrect point of contact for North America. Try giving the fine people in Trenton NJ a call (yes! direct active communication still gets the best results).

  6. True… 215 is “big” relative to friends I ride with regularly. Most of them are in the 160-170 range 😉

    Still… it’s early, but I’m already feeling like this is the best tire I’ve ever ridden.

    Tried it a bunch of different pressures… 50, 60, 70, 80, 90 and 100 PSI. They all seemed to work well. For tooling around town 80PSI is the sweet spot. If I’m riding faster and hitting turns pretty hard… 90 is where it’s at.

  7. Hi Dane,

    I’m Hutchinson’s Sales and Marketing Manager. Sorry to read that we didn’t get back to you. We usually reply within 24h so I’m a bit surprised.

    Please contact me through our warranty address (it directly forwards the emails to 3 persons in our US office, including me) and I’ll get back to you asap: warrantybiketires@hutchinsoninc.com.



  8. You know 28mm is nice and all but I have to ponder why they did not come out with a 25mm instead? Considering 25 is the new 23…

  9. i like 28mm for a long distance training tire. wear, comfort and puncture resistance. on continentals right now, will be getting these next.

    @RCSpeed, for me 25mm is not much difference from 23mm. if weight is an issue you are not using these tires in the right format. training, hard riding, rough terrain……

  10. Not 100% Iceman, but I think you should be fine. I was able to put the wheels on with no adjustment to the brakes, I run the old Zero Gs. The rims are Reynolds 32s… which I think are about 21mm wide. The tire sits just a bit wider than the rim. Just a slight rub to the tire as I pushed it through. I do run my brakes a little wide however. Hope that helps.

  11. Related question to my 5/20/13 post. My frame manufacturer advertises that the frame will accept 25mm rear tires and I have an Easton EC90 fork. Any reason to believe the Secteur tire is “too tall?” When inflated, if it’s not any taller than a Fusion 3 tubeless or an Intensive tubeless – both of which fit fine on my bike – I’m ok. I just get a little nervous reading the BikeRumor bit above when the talk about the accumulation between the fork and tire.

  12. AJAX – WTF are you talking about? I’ve been on tubeless for a year and they’re outstanding. I just mounted up a pair of these Secteurs for a gravel ride I have this weekend. So far, they’ve also been very good.

  13. I can’t get my eagerly awaited Secteurs to hold air. They go flat overnight. They lose air while riding to the point of dropping from 80 to 35 psi in less than 2 hours. I have been using Fusion 3’s, atoms, and Intensives tubeless for 2-3 years and love them. The Secteurs on the same wheels (Stan’s rims, valves, tape, sealant) simply don’t work very well. There is no visible sealant leakage, and I have seen some improvement after adding another oz (3 total), shaking, swishing, and re-inflating daily for over two weeks. That seems like some pretty excessive preparation of a tire. So, I have no confidence in these tires at this point.

  14. MER – I have the same problem with the Secteurs. I have several sets of wheels with Fusion 3 tubeless and Intensive Tubeless and they do fine – have for several years.

    May not matter – I use an Easton EC90 fork and the Secteur is too tall. Will not clear the EC 90 fork. Use will be limited to cyclocross frame I have as spare town bike. But that’s only if I can figure out why they are not holding air!!

    • @MER, Iceman, if both of you are using rims with tape, try adding another layer. My guess would be the bead on the Secteur might be smaller than the other tires in an attempt to get the weight down, and if so will require a tighter seal on the rim. Wheels like the Bontrager TLRs that have an aggressive bead lock seem to have no problem with the tires (my Secteurs are holding air better than many tubeless I’ve tried), but wheels that use rim tape might not have a tight enough seal. Using another layer of tape or so will build up the base and possibly seal the tire better.

  15. Hey Zach – thanks again for reviewing the Sector 28’s and for giving me your take on 25mm Bontrager R3’s vs the Sector 28’s on Twitter, much appreciated. I decided to go with the Bontrager’s for a bit of cost savings and because of your take, but my friend and blog contributor Bryan, has been riding and racing the Sector’s and loves them. Here is his full take: http://www.averagecyclist.com/2013/08/review-hutchinson-sector-28-tubeless.html

    Thanks again though for reviewing both and giving your feedback. I needed a push.

  16. Ajax…Permanently out to lunch. Tubeless tires will eclipse standard fare clinchers and sew-ups. It’s already happening.

    Tubes are an anachronism and it’s long overdue that they become history in the road cycling world.

  17. Have two sets of rims with same dimensions: Bontrager Race TLR and Bontrager RXL TLR. One set is mounted with Bontrager R3 tubeless 25mm, the other with Hutchison Sector 28. Myu 2002 Litespeed with Shimano Ultegra 6500 brake calipers (working with SRAM Force 10 speed leavers) accepts the larger Sectors. The Trek Domane 5.2 with SRAM Force will NOT. Domane fork and frame have plenty of clearance, but rear SRAM caliper does not. Therefore I have purchased a Shimano Ultegra 6600 (SHORT PULL) rear caliper for the Domane.

    The difference between SRAM and Shimano brake calipers is style. Shimano continues to use the classic arched shape, whereas SRAM runs the cross arms straight from one side to other, robbing clearance.

    By the way, my measurements of Bontrager R3 25mm and of Hutchinson Sector 28 cross section on these rims matches closely to those submitted above: 25.3mm and 27.8mm, respectively. When measuring the height of the tire from rim, there is greater difference, Bontrager R3 measuring 23mm height (25mm width), Hutchinson Sector measuring 27.8mm height (27.8mm width). So the Sector has much higher volume, whereas the Bontrager has lower profile. I think this higher volume has more to do with shock absorption than does width.

  18. I bought pair of sectors after riding both the smaller tires, 23 and 25. Have issue with front tire holding air. Deflates within couple days. Finally placed it in water in sink and could see air seeping from sidewall. Not the seal or tape or valve stem. actually out of the side wall. guess I’ll open up and add more sealant and swish some more see if that will help any. Already did that once.

  19. The sectors seated easily to the bonti rxl tubeless ready wheels and felt confident through the dirt and off-road sections of the spy belgian waffle ride. Psi was 80, rider weight 180.
