I had an 853 steel Howler, 2005 I think. Very nice frame, but eventually broke at the drive side chainstay, where the tube was pressed/bent to improve the chainring clearance. Around the time mine broke, I heard of several other 853 ones suffering the same fate with near identical failures to mine. Given that there really weren’t very many made (less than 100?, someone may know) that seemed like a high failure rate and probable design fault.
Fond memories of mine. My first DIY bike build, and had some great rides and overseas trips with it. Still got the frame hanging up in the shed, with the thought of getting a new stay welded in one day….It’ll probably still be hanging there in 20 years 🙂
