The 50mm profile front and rear is the all-rounder of the range, aimed at riders who want aero gains on flat roads without giving up control on climbs, descents and gusty days. Partington lists the wheelset at 1,200 grams, with a tolerance of plus or minus 1 percent.\u003c\/p\u003e\n\n\u003ch3\u003eA Ground-Up Redesign\u003c\/h3\u003e\n\u003cp\u003ePartington describes the R-Series as a complete redesign of its carbon road wheels, not a step change from the MKII line. The rim, spoke and hub were developed together as one system, and the brand's stated goal is for each part to work with the others rather than being tuned alone. The rim is the AERON carbon fiber construction, a multi-material composite using Toray fibers around a PMI foam core. Partington says the foam damps road vibration and stabilizes the carbon structure so the laminate can be tuned for radial compliance, which is intended to cut rider fatigue on rough roads.\u003c\/p\u003e\n\u003cp\u003eRim shapes were developed in-house and refined through CFD analysis and testing at the SASI wind tunnel in Adelaide. Partington says it looked at more than outright drag. It balanced aerodynamic forces around the steering axis to reduce steering disturbances, so the wheels are meant to feel calmer in crosswinds and need fewer corrections. The brand describes the 50mm depth as a balance between aerodynamic efficiency across typical yaw angles and stable handling.\u003c\/p\u003e\n\n\u003ch3\u003eRim, Spokes and Tires\u003c\/h3\u003e\n\u003cp\u003eThe rims are hooked, work with tubeless or tubed tires, and need no rim tape. Inner width is 23mm and outer width is 34mm. The wheelset is optimized for tires up to 30mm, with a recommended 28mm front and 30mm rear, compatibility from 28mm to 32mm, and a maximum pressure of 87 psi. That puts it squarely in modern wide-tire territory, where a tubeless setup on this kind of rim tends to give the best mix of speed and grip.\u003c\/p\u003e\n\u003cp\u003ePartington FLEXON carbon spokes are made from continuous Toray intermediate-modulus carbon fiber and laid out 18 front, 21 rear. They are replaceable, using steel pins and inserts. Partington lists lateral stiffness for the 50mm wheel at 42 N\/mm.\u003c\/p\u003e\n\n\u003ch3\u003eHub and Drive\u003c\/h3\u003e\n\u003cp\u003eThe PERFORM hub is an anodized silver aluminum design that Partington shaped with finite element analysis to cut mass while holding stiffness. Its floating bearing architecture is arranged for low rolling friction, long bearing life and an even spread of load, and the Performance wheelset uses steel bearings. The freehub is a self-contained ratchet system, available for Shimano HG, SRAM XDR and Campagnolo N3W.\u003c\/p\u003e\n\u003cp\u003eThe ratchet was redesigned for the R-Series and has 68 engagement points, a 38 percent increase over the MKII wheelsets. A helical drive system is meant to keep engagement positive under heavy load, with minimal freewheeling drag. When you stand out of a corner or jump on a sprint, that means less slack before the wheel picks up drive. Brakes are Centerlock disc only.\u003c\/p\u003e\n\n\u003ch3\u003eWho It Suits\u003c\/h3\u003e\n\u003cp\u003eThis is a wheelset for road racing, fast group rides and long days where wind and mixed terrain are part of the plan. The stated system weight limit is 110 kg, which covers rider, bike and gear together, so heavier riders should check that figure before buying. Partington also offers the same platform in a Ti version with ceramic bearings and a titanium ratchet; the Performance wheelset is the steel-bearing option in the range.\u003c\/p\u003e\n\u003cp\u003eEach wheel ships with a padded wheel bag, a bidon, an exercise towel, a valve and a rotor lockring. Partington covers the wheels with a 2-year manufacturer warranty and a multi-year crash replacement program, both requiring registration at time of purchase. Decals are available in Strong White and Subtle White.\u003c\/p\u003e\n\u003c!-- VERIFY: RA Cycles page lists \"Max Rider Weight: 242 lbs,\" but Partington lists \"Max System Weight 110 kg\" (rider + bike + gear). Description uses the manufacturer's system-weight wording. Consider correcting the RA spec. --\u003e\n\u003c!-- VERIFY: Partington's R-Series Performance page lists steel bearings; the technology page's ratchet and floating bearing copy covers both Performance and Performance Ti. Confirm the 68-point ratchet applies to the non-Ti hub as written. --\u003e\n\u003c\/div\u003e","brand":"Partington","offers":[{"title":"Strong White \/ Campagnolo N3W","offer_id":46436924620844,"sku":"RP-5050-STW-N3W","price":5520.0,"currency_code":"USD","in_stock":true},{"title":"Strong White \/ HG11 (Shimano \/ SRAM 11s)","offer_id":46436924653612,"sku":"RP-5050-STW-SHM","price":5520.0,"currency_code":"USD","in_stock":true},{"title":"Strong White \/ XDR Driver","offer_id":46436924686380,"sku":"RP-5050-STW-XDR","price":5520.0,"currency_code":"USD","in_stock":true},{"title":"Subtle White \/ Campagnolo N3W","offer_id":46436924719148,"sku":"RP-5050-SUW-N3W","price":5520.0,"currency_code":"USD","in_stock":true},{"title":"Subtle White \/ HG11 (Shimano \/ SRAM 11s)","offer_id":46436924751916,"sku":"RP-5050-SUW-SHM","price":5520.0,"currency_code":"USD","in_stock":true},{"title":"Subtle White \/ XDR Driver","offer_id":46436924784684,"sku":"RP-5050-SUW-XDR","price":5520.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/PARTINGTON-R-SERIES-PERFORMANCE-50-50-WHEELSET-STRONG-WHITE_a24d4ba0-bf3a-46c3-8a7b-5757ad1828bd.jpg?v=1792592927","url":"https:\/\/racycles.com\/es\/products\/partington-r-series-performance-5050-wheelset","provider":"RA Cycles","version":"1.0","type":"link"}
