Vintage 1983 Mantis XCR Mountain Bike Cunningham

Description

Description

The early Mantis mountain bikes are reasonably obscure mainly because of their rarity. Unlike Ritcheys, even the fillet brazed ones which were made by the 1000s of even Potts which were made well in the 100s, only a handful of fillet brazed Mantis bikes were ever made. I’ve been tracking quite a lot of early Mantis bikes including the XCR, Sherpa and Valkyries and have only recorded about 35 bikes in my serial number registry. These are among the rarest of the rare and to find one let alone ride one is a real treat. I had this bike at the 2017 Keysville classic race and Joe Breeze himself asked if I would loan the bike to the Mountain Bike Hall of Fame and Museum in Marin. If it weren’t for a cross country move and new house purchase I would have been happy to send it there for a few years.
This 1983 Mantis XCR is likely one of the very first bikes built by Richard Cunningham after starting Mantis. The fillet brazed XCR was only made for one year before being replaced by the composite Aluminum/Steel version in 1984. According to Richard he made between 7-10 of these. The XCR and Sherpa were the top of the line offerings from Mantis that year in addition to the TIG welded Overland. The XCR had more aggressive geometry and was intended for racing whereas the Sherpa was a touring bike. Also, unlike the Sherpa which was made for another 3-4 years and numbered in the 30s the XCR is exceedingly rare with only five bikes known to be in existence one of which resides in the Shimano museum in Japan.  
The XCR and Sherpa were made from oversize 4130 chrome moly main triangle with Columbus stays and Campagnolo dropouts and stand aside from other fillet brazed steel bikes because of their uniquely profiled fillets at the top tube junctions with the head tube and seat tube. With the exception of the hand made frame and biplane fork the bike features a custom made Mantis stem with internal cable routing, Mantis 6061 Aluminum handlebar, Mantis custom made seatpost with a Shimano DX BMX head and cust modified Campagnolo road cranks which enable the use of a granny gear. The wheels are built with Durex Ambrosio rims laced to Phil Wood hubs held in with Campagnolo quick releases. The drive train is Suntour Mountech and brakes are Shimano M700 with Tomasseli brake levers. The tires shown are Specialized Stumpjumpers but the actual tires on the bike are NOS IRC X1s which are the correct tires for this bike, I just didn’t have them at the time these photos were taken.

Condition:
The bike in amazing condition. The paint is 100% original and With the exception of some minor chain suck has virtually no flaws. The decals are original and in amazing condition. You’ll be able to still see the original bike shop sticker on the seat tube! The majority of the parts are new or in as new condition. The Campagnolo cranks and Shimano cantilever brakes have been refinished and clear anodized at the same time as the Tomasseli levers and bodies were refinished and anodized black. For a 34 year bike this XCR in virtually new condition. Everything works flawlessly and the bike is completely trail worthy. I’ve taken it for a couple short spins and at the same time as it clearly showed the primitive nature of the components it was very pleasant to ride and everything worked as well as it could.
Shipping:
Domestic shipping will be handled via FedEx and will carry insurance for the full value of the bike. I am happy to ship the bike world wide, though out of the country shipments will likely have to be in two boxes because of the size of the bike. I will be able to ship via USPS priority mail which at the same time as the cheapest but only offers $500 of insurance, so the buyer will accept responsibility if the bike is lost. I will be able to also ship via FedEx or DHL which will offer full value insurance but will cost significantly more and the buyer will be responsible for all import taxes and duties for the full value of the bike.
