With specs like carbon spokes, nearly 50mm mid-depth and super-wide aero carbon rims, class-leading wind tunnel performance numbers, and a total wheelset weight of just 1156g the new Hunt 4AM Limitless Ti UD Carbon Spoke wheels look pretty amazing.When Hunt launched their 5AM Limitless ultralight aero wheels with carbon spokes just back in April, we were already surprised at how well they balanced leading aerodynamic performance with an ultralight weight of just 1212g. (And we learned that they were referring to rim depths being Aero Maximised, not ante meridiem, or getting up super early in the morning to ride road bikes.)And now Hunt are back here again with another, more versatile set of slightly shallower aero carbon wheels, and theyre even lighter still! Plus, those 5AMs and these new 4AMs also add more affordable and still aero versions with bladed steel spokes, too.Hunt 4AM Limitless ultralight aero wheels with carbon spokes(Photos/Hunt)Hunt describes these new 4AM wheels as optimized for ultralight responsiveness and category-leading aero efficiency for high alpine racing environments. But its hard for us to just get past the simple fact that they are super aero and ultra-lightweight. Hunt says they are wind tunnel tested to provide a 1.4-Watt aero advantage over the Tour de France-winning ENVE SES 4.5 Pro, while offering a 139-gram weight savings, which is pretty wild.And while these new Hunt 4AM wheels are some of the most expensive the brand has ever sold, theyre still 15% cheaper than Pogis wheels.Key Limitless Aero Maximised TechYou still get front- & rear-specific 23mm internal hooked carbon rims like the 5AMs, designed to go fastest with modern 28-30mm wide tires. Wider outside and deeper up front, where the wind is cleaner, and where its more important to keep airflow attached at higher yaw angles for controllable handling & stability, even in variable winds.Then, lighter, narrower, and incrementally shallower out back, where theres less aero effect. And you still only need 15 of the aerofoil bladed Vonoa carbon spokes up front, and 18 in the rear, all with recessed nipples for smooth airflow.Hunt describes their Limitless aero wheel design as a more holistic approach, a 5-stage process that includes initial CFD design, wind tunnel testing with wheel-only, in-bike, and then with a real rider, followed by real-world outdoor testing with AeroSensor drag sensors. Thats how their wheels go from aero design to Aero Maximised.Whats new, then for 4AM?Now for the new 4AM, the front rim is 49.5mm deep by 34.2mm outside, again with Hunts low-density polymer Limitless Width Aero Tech filler inside that keeps rim weight low. Out back, the rim is 47mm deep x 30mm wide external. Sure, theyre almost 50mm deep, but not quite, hence the 4 in their name. But still about 8mm shorter than the 5AM.How fast are the new wheels?Hunt says the new 4AM Limitless Ti_UD Carbon Spoke wheels outperform the best mid-depth 40-50mm deep aero wheels on the market. And they do it at both lighter weight and a more accessible (if not quite affordable) pricepoint. Hunt also says the 4AMs are pretty much as fast as some top wheels in the next deeper category, too.In wind tunnel testing performed at Silverstone Sports Engineering Hub (both wheels on bike), mounted with 30mm tyres at 45 km/h, the 4AM Limitless Ti_UD wheelset (1156g) tests 1.4 watts faster than the ENVE 4.5 Pro while being 139 grams lighter. Compared to the significantly deeper and heavier DT Swiss 55 ARC Dicut BD (1479g) and Reserve 57/64 Turbulent Aero (1554g) wheels, the 4AM Limitless Ti_UD performs within 0.1 watt.Read more if you want to nerd out in their full in-depth whitepaper on the 4AM & 5AM wheelsets, here.Tech detailsaerodynamic carbon rims made from a mix of T700, T800 & T1000 UD carbon fiberplus low-density high-mod Mitsubishi Pyrofil HR 40 12M fiber filler in the front rim49.5mm deep x 34.2mm wide front wheel47mm deep x 30mm wide rear wheel23mm internal hooked tubeless carbon rims, front & rearhigh-gloss finish for easy cleaning15 front &18 rear Ti_UD Vonoa aero bladed carbon spokes with 6AL-4V titanium hardwareCNC-machined 7075-T6 Hunt Chase SLC centerlock disc brake hubs48T, 7.5 engagement H_Ratchet DBL freehubsealed stainless steel or hybrid (ceramic balls + stainless races) CeramicSpeed bearingsoptimized aerodynamics for 28mm-30mm tiresETRTO compatible with 28-50mm tires, tubeless or clincherfrom 1156g wheelset weight (claimed)UCI approvedHunt 4AM Limitless aero wheel Pricing & optionsHunts new ultralight aero carbon 4AM Limitless wheels are offered in three versions.The fastest and lightest are the Hunt 4AM Limitless Ti_UD Carbon Spoke wheels with hybrid CeramicSpeed bearings, selling for 2449 / $3159 / 2859, or fifty buckaroos less than the 5AMs. Next up are the 4AM Limitless Ti_UD Carbon Spoke wheels with stainless steel bearings at a slightly more approachable 1959 / $2559 / 2299, again a bit cheaper than the same 5AMs. New for the 4AM family are wheels with more conventional triple-butted, aero bladed Pillar SuperWing 20 spokes, too. With 20 front & 24 rear, and still with recessed nipples. Sticking with stainless bearings and otherwise everything else the same, the 4AM Limitless Steel Spoke Wheels weigh 1283g, still are 1.13W faster than those ENVE SES 4.5 Pro wheels, but are quite a bit more affordable at 1659 / $2359 / 1959.Hunt 5AM Limitless wheels with steel spokes, too!And now in addition to the 3 4AMs there are now 3 5AM options too. The newly added 5AM Limitless Steel Spoke Wheels weigh 1339g, with 20 front/24 rear Pillar SuperWing 20 spokes, and sell for 1699 / $2399 / 1999.New Hunt 4AM & 5AM Limitless wheel real availabilityAll of the new 4AM and 5AM Limitless wheels are available to pre-order starting today. But the different wheels will start showing up in your mailbox at different times.
