This may be a long shot but what the heck. A little mystery for your afternoon.
I bought my MTB frame at a local bike shop owned by a friend of a friend and later finished off the rest of the bike at the same shop. The price was 300 dollars so it seemed like a decent find as I had been eying 2000 dollar GT carbon frames. The shop was a Merida dealer and they said the frame came from the back door of the factory in Taiwan. No big surprise, most of the "high tech" things in mainland China are that way. The shop had several of the frames in different sizes, all larger, I happen to ride a larger bike than most Chinese (being an American with an American frame) so it worked out great for me.
The hard tail frame is carbon fiber and a tag on it said 1213 grams. There are no stickers or anything written on the frame except on the bottom of the...I don't know what you call it, the place where the pedals and front drive train are connected to the bike. That place....anyway it has what looks like a serial number and another which looks like a batch number.
There is some speculation that this might be a Merida FCX however there are a few places that don’t look the same as the FCX’s of that time. Other speculation is that it’s a Specialized frame made for them by Merida because many of the details look more Specialized than Merida.
Anyway maybe someone out there will recognize this frame. Its not really important for me to know what brand it is, I ride the thing none the less (as you can see from the pictures) but its just something we have been curious about here for a while.
Please excuse my newbie descriptions, I am not sure what everything is called.
This is what the whole thing looks like.
These are the numbers
Unusual detail #1. The carbon ridge that comes together on both sides at a raised place on top. Also on Merida bikes this area is more bulbous and the lines are not so straight.
Unusual detail #2 the bottom “strut”is straight unlike many photos I can seen online of Merida frames where the bottom strut is curved where they come together. Also note how large the weave of the carbon is which is around 10mm. On Merida frames I have seen where you can see the weave it is a much tighter around 6mm.
The back takes disks and whatever those older style brakes are called. Also the back is carbon all way near to the end where the attachment area is and that seems to be metal. There are is a bolt on both of the upper struts here and none on the bottom, as if it could be taken apart or designed to take some bending force there. Also the big fat strut in the top left has a layer of carbon going around the normal weave, like if you wrapped duct tape around it.
I don’t know if this helps anyone with anything. The sticker is my warranty sticker, stuck in a very bad place.
