{"product_id":"duke-sierra-27-climber-wheelset","title":"DUKE Sierra 27 Climber Wheelset","description":"\u003cp\u003eEvery wheel brand claims their gravel range \"climbs well.\" DUKE built one that actually commits to it. The Sierra 27 is the light end of the new Sierra family from the French operation that has been hand-building wheels for 18 years: a 280-gram, 27mm-deep rim in Toray T1100 carbon, laid up with the SLR5 process DUKE developed for its most advanced mountain bike rims. Built on DUKE's Mad Max hubs, the pair starts at 1,099 grams — a number that used to require tubulars, a road bike, and a small fortune.\u003c\/p\u003e\n\u003cp\u003eThe Sierra 27 is shaped for the rides where gravel gets vertical: adventure routes, hardpack, long days with serious elevation gain. The 29mm internal width — widest in the Sierra family — lets a 40mm tire (or up to 2.2\") take its full shape at low pressure, and DUKE's DRC tuning does the rest: vibration filtered before it reaches your hands, grip maintained on broken surfaces, energy returned rather than absorbed. Light wheels that beat you up are a false economy; these don't.\u003c\/p\u003e\n\u003cp\u003eConstruction is the full SLR5 playbook. SpokeCore molds every spoke hole into the layup rather than drilling through cured carbon, preserving fiber integrity and letting DUKE control stiffness precisely. The AntiPinch bead design shrugs off square-edge hits at the low pressures this wheel invites. And the VFP finish skips varnish entirely — lighter, more scratch-resistant, and dramatically cleaner to produce. Versus the Baccara WRX it supersedes, the rim alone drops 30 grams. Hooked, tubeless-ready, with DUKE tape and valves in the box.\u003c\/p\u003e\n\u003cp\u003eEvery set is hand-built to order: Mad Max or Tune Nano hubs, Sapim CX-Ray spokes standard with Tune's CxCarbon available on the top build, and your choice of freehub — XDR, HG11, N3W, or MicroSpline. If you're looking for a fully custom build around these rims — spoke counts, decals, a hub we don't list — \u003ca href=\"\/en-gb\/pages\/contact\"\u003ereach out\u003c\/a\u003e for a quote.\u003c\/p\u003e","brand":"Duke","offers":[{"title":"Mad Max \/ XDR","offer_id":51952878059837,"sku":"210000065505","price":2793.0,"currency_code":"GBP","in_stock":false},{"title":"Mad Max \/ HG11","offer_id":51952878092605,"sku":"210000065506","price":2793.0,"currency_code":"GBP","in_stock":false},{"title":"Mad Max \/ N3W","offer_id":51952878125373,"sku":"210000065507","price":2793.0,"currency_code":"GBP","in_stock":false},{"title":"Mad Max \/ MicroSpline","offer_id":51952878158141,"sku":"210000065508","price":2793.0,"currency_code":"GBP","in_stock":false},{"title":"Tune Nano \/ XDR","offer_id":51952878190909,"sku":"210000065509","price":2944.0,"currency_code":"GBP","in_stock":false},{"title":"Tune Nano \/ HG11","offer_id":51952878223677,"sku":"210000065510","price":2944.0,"currency_code":"GBP","in_stock":false},{"title":"Tune Nano \/ N3W","offer_id":51952878256445,"sku":"210000065511","price":2944.0,"currency_code":"GBP","in_stock":false},{"title":"Tune Nano \/ MicroSpline","offer_id":51952878289213,"sku":"210000065512","price":2944.0,"currency_code":"GBP","in_stock":false},{"title":"Tune Nano w\/Cx Carbon Spokes \/ XDR","offer_id":51952878321981,"sku":"210000065513","price":3247.0,"currency_code":"GBP","in_stock":false},{"title":"Tune Nano w\/Cx Carbon Spokes \/ HG11","offer_id":51952878387517,"sku":"210000065514","price":3247.0,"currency_code":"GBP","in_stock":false},{"title":"Tune Nano w\/Cx Carbon Spokes \/ N3W","offer_id":51952878420285,"sku":"210000065515","price":3247.0,"currency_code":"GBP","in_stock":false},{"title":"Tune Nano w\/Cx Carbon Spokes \/ MicroSpline","offer_id":51952878453053,"sku":"210000065516","price":3247.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1234\/3118\/files\/Sierra27Wheelset.jpg?v=1783631922","url":"https:\/\/abovecategory.com\/en-gb\/products\/duke-sierra-27-climber-wheelset","provider":"Above Category","version":"1.0","type":"link"}
