BMC impec 55cm race fitPurchased new in 2011/12. BMC created a new manufacturing facility in Switzerland specifically to manufacture this frame. The process was unique and expensive.This is neither a moulded frame, nor a typical tube-to-tube construction. It has elements of both yet takes them to new levels. This is because BMC’s engineers realised they needed to more precisely control fabrication processes in order to get the ride quality they were looking for. All the tubes are made via BMC’s Load Specific Weave (LSW) process. They weave them with an eye to putting more material where it’s needed and less where it isn’t. There isn’t a round tube on the bike. After the tubes are woven, the resulting carbon-fibre sleeve is placed over a negative mould and a positive mould goes over that, with the resin injected once this is done. The process gives shape and rigid form and incredible compaction. The finished tubes are joined to nodes, part of BMC’s Shell Node Concept (SNC), moulded two-piece ultra-light joints that sandwich the tubes and permanently affixed with epoxy. The whole process is automated, so that each element is precisely controlled the same exact way each time it is created and equally precisely joined together each time. Every frame comes out perfectly with the same exact characteristics for its size. The one way that the Impecs differ is by size. Realising that bigger riders on bigger frames exact more force, the weaves change through the size run to reflect this reality. This way, smaller riders aren’t getting an overbuilt frame and bigger riders won’t have an underbuilt one.The frameset alone retailed for more than £4k in the UK. All in cost of complete bike new £11k+The bike has been used, but not so much over the past few years, hence the sale. I would consider it the most comfortable performance bike I have ridden and that list includes Colnago, Cérvelo and Look. The unique design and manufacture means there are not many out there, so something of a future collector’s item.Groupset: Campagnolo Record 11-speed 50/34 172.5mm cranks.Wheels: Mavic SSC Comete Carbone Exalith clinchers, carbon spokes.Perfect condition.Bars: Enve 42cm.Stem: Enve 110mm.Saddle: Fizik Tri carbon rail.Frame: 55cm (Seat tube 555mm/Top tube 560mm/Head tube 171mm).Condition is exceptional. The only cosmetic flaws are a couple of small chips and a white-ish blooming in some areas under the matt clear coat varnish, which I show in the photos, mostly near the junction with the node shells. I understand this could be moisture (efflorescence) having got under the varnish but is cosmetic only.I’m also including with the sale the following impec branded items:BMC impec bike bagBMC impec water bottles and cageBMC impec drive-chain coverBMC impec Assos jersey and shorts LThe bicycle is also for sale by consignment elsewhere. Viewing and test rides welcome.
