I had almost completed my Dean Colonal Titanium City Bike Single Speed / Fixie build, but ran into a not so optimum mounting point for my headlight. When i found a very nice used Moots Ti Braced Riser MTB handlebar on ebay a awhile ago (sadly,....now discontinued), i found that the cross brace interfered with attaching my headlight. When the light was tried outside the cross braced area, it would not point straight ahead because of the swept back area of the bar. I was losing a substantial amount of coverage. After thinking it over awhile, i contacted Ti Cycles Fabrication, and they agreed to make me up a custom 30 mm tall 1-1/8" Ti Headset spacer, with a 2 inch length of 22.2 mm mtb handlebar stock welded on. (Eric is easy to work with

This would allow me to position my light straight ahead, and looks really good to boot! I decided on the 30mm Ti headset spacer, even though i use a 55 mm spacer stack,.....so that i would have some ability to adjust the mount's height to work around cables and such. In my case i needed this spacer/light mount to be as high as possible for the thick light to clear my top tube, even with the pretty long headtube on this XL Dean Frame. This also leaves a few mm's on either side of the welds to not interfere with the spacer flat areas. This mounting headset spacer might also work well with some bike computers, and a double sided one could be made for those with more room needed to mount things. Had i not had a Ti bike, i could just have easily gone with an aluminum spacer and handlebar piece which i already had on hand, and had it tig welded by a local shop for probably less than $25 or so. But in this case i wanted to match up the Ti "theme". :embarrassed: Ti fabrication being what it is,..... i bit the bullet and told them what i wanted, and i received it today. (it's worth every penny!) One thing i really liked is the tight fit of the Ti Cycles headset spacer onto my full length (300 mm) Surly Steamroller fork's steerer tube. Only hand pressure needed but absolutely NO slop on my particular steerer tube. (i did use just a little anti-seize just in case for years down the line). My Dean Ti 50 mm short stem is tight on the steerer anyway, and i have to twist that on to get it started due to the springiness of Ti, so i have absolutely no worry the anti seize will cause any slipping. It came with no end cap,....but i have dozens sitting around as most do who have been biking awhile and i never asked so din't expect one. Because of the hole used to purge the air when welding, i wanted to keep any rain from getting in and reaching my steel steer tube. The cap will do that. Anyway,.....i've not seen anything like this out there,.....so thought i would post some pictures, as i'm sure i'm not the only one to run into this.
This is the max bar turn i can get with this particular light. The Night Rider Lumina 650 has a deep profile, but if i can find a reasonably priced steel road fork with a 15-20 mm longer steerer tube (which i'd prefer anyway due to right shoulder bone spur pain), then this light will totally clear the top tube. A thinner profile light would do the same. As it is now i never turn the bars that much in use on my routes, but in an "emergency" you never know
