Aggressive tires on an unassuming bike

As far as I can tell, what I call the "b'Twin Conception Decathlon mountain bike" is a bike made by French manufacturer b'Twin, named the Conception, that was sold in a store in France called Decathlon. The Decathlon website is in French, so if you don't speak French, here's a link to their UK site, where all of the prices are in pounds, or £, which is oddly entertaining to me, because I'm American.



Don't let worn-out parts get "b'Twin" you and an enjoyable mountain biking experience.
Always check compatibility before ordering parts for your bicycle.
All bike repairs should be performed by a qualified bicycle mechanic.

Hank Hill, I'm not

The b'Twin Conception is a weird-looking mountain bike. In fact, it might have been designed as a hybrid, based on the not-quite-offroad-not-quite-onroad tires. The steel frame appears to be a unisex design, with an angled intermediary tube between the top of the seat tube and the center of the down tube. The hole in the yellow b'Twin safety pad reveals a "5-five" decal. What does that mean? I don't know. There aren't exactly five of anything on this bike.

Milk crate detail

The Conception uses Grip Shifters, an Altus front derailleur, and an SRAM 3.0 rear derailleur to help run through all 18 gears on the way from the Eiffel Tower to the Louvre. The brake levers are by Alhonga (I figured that out by rotating the photo 180 degrees and zooming in for a close-up). A set of ill-fitting plastic fenders cover the street/mountain tires, and a suspension fork and matching seatpost round out out the b'Twin's fairly unimpressive parts package.

The same photo, cropped 'n' zoomed

I don't remember when I bought this bike, but it must have been before I started shooting photos in the ghetto, because here it is in all its glory, propped up against a milk crate on the street in front of my house. At least I remembered to mow my lawn first.
