Hi, just bought this 26" steel hardtail. Reasonably to very light frame 4.1lb with headset cups . It has Ritchey dropouts, a forward facing seat post bolt guide, s shaped stays and a disc mount. Very curious as to what make and model it is - has Kona stickers on it and previous owner said it was a Kona. Serial Number is B00080013. Any help would be appreciated.
