2015 Motobecane Boris X-7
Well its almost been a year since i purchased the Motobecane Boris. X-7
What is it? The Boris is what is termed a FatBike its basically a Mtn Bike with really fat tires. it was primarily used in really snowy conditions or in the Sand. there is a race in Alaska that uses alot of Fat Bikes called the “IditaBike” they use a 26×4.0 tire (some will use a even bigger tire a 26×5.0) Surley was the first to bring out a fat bike to the masses with the Surley Pugsley. It is a good bike but anymore has some mechanical items that are not up to par. Their new version of the Pugsley which is called the Ice Cream Truck is a nice bike. Specialized has entered the Fatbike Market with their Fat Boy and Trek also has one called the Farley
How much did i use it? Well during the Winter and the early Spring it was the only bike to leave the garage. Snow riding was alot of fun (and quite a workout) There was something about it how it just floated across the snow. Mostly any distance riding during late spring and summer, I chose other bikes. Although it did get some attention when i would ride it downtown.
Yeah but why a Motobecane? Well this was more a economic issue than any thing. Bikes like this are Seasonal and not the best all around bike to own, so i know that it wasnt going to get all the riding chores. The Motobecane Boris had a good mix of components that were Mid Level. but nothing that will add to the cost of ownership . Sure i could have bought a Specialized Fat Boy or a Trek Farley but i really didnt want to spend $2000.00+ for the bike. On the flip side i didnt want to buy the target level fat bike since they would not be up to most quality levels. the Boris Sat out in the middle with its SRAM X-7 Shifting on a 10 Speed Cassette and Avid BB5 Disc Brakes. They seemed to have a good price point for the specs.
Cable Disc Brakes??Why?: Well that goes back to the snow biking and the frigid cold. it would get so cold that the mineral Oil or the fluid that was being used in the Hydraulic disc Brakes would get so cold it would thicken up and cause the fluid to lock up at the caliper causing the brakes not to work. Cables do not have this problem.
The Bike came with three different rim strips which when you have drilled rims will show through. There was black Rubber, White and Blue (as seen below). I ran the blue for a while but picked up some Orange Surly rim strips and are using them currently.

60 CM frame, Frame gfx are in pretty good shape. alot of scratches on the frame itself. The rear wheel is incorrect for the bike. the brake cable is to short, not even enough to go through all of the braze ons. Brake levers are not the original Suntour GPX but DiaCompe Gran Compes. i did dig the red cables and red hood and bar tape
Original Suntour GPX Cranks with GPX front deraileur
Suntour GPX Rear Derailuer and replacement Shimano 7 speed Freewheel
Suntour GPX Brake calipers. they are kind of neat as they have hidden brake springs.. Look ma no springs.
Crazy late 80’s decals nothing could be without geometric shapes. higher quality frame with Tange #1 tubing
Logo says it all Expert IronMan Dave Scott.

I have been enjoying this bike. i have returned the pedals back to the stock 105 Toe Clip pedals and dare i say ..yes i added back the Biopace Chainrings. the bike is original enough i felt the bike needed the original chainrings.

finally someone has posted scans for the 1986 & 1987 Centurion bicycle catalogs!
they are here:
My latest acquistion, is a 1987 Centurion Dave Scott IronMan Expert. This bike is in great shape the frame has very little scratches. it is the Magenta and Yellow paint scheme which is mistaken for Pink quite regularly. This one is a 60cm Frame. it is mostly original except for a few pieces.
I have wanted one of these for many years, in fact since they came out, i remember seeing them at the Bike Shop and hoping one day i would own one. Now i do!

Not sure if they are correct but the pedal grips are round like rollers. not sure if i like that idea.
Vetta was a popular cycling accessories company in the last half of the 80’s they made all kinds of items from helmets as you see here to seats to racks and waterbottle cages. my first helmet with my cycling was a Red Vetta Corsa
