Hi all, I'm Mark.

I posted pics/descriptions of my first single-speed conversion in the gallery if you're interested! Thanks.

Hophead----I didn't want any extra stuff hanging on my bike like tensioners------that's part of the appeal of SS to me----so I fiddled around with cog sizes and chain length. I ended up using a 1/2-link, but this, in combination with getting a nice straight chainline has worked out great. I've been on several long rides with no hint whatsoever of losing the chain.

Yeah, I'm not a big fan of dangly derailleur lookin' thing-a-ma-bobs on my ss either. I did the same thing with my singlespeed road bike conversion. It was a little easier though since it has horizontal dropouts.

I'd love to find an old roadbike with horizontal dropouts to convert to SS! I've been looking.

They're out there. My Schwinn frankenbike was a dumpster rescue that one of my buddies grabbed up. Got a wheel set at a swap meet and a few other pieces parts here and there. I think I've got around $100 in it.

I'm curioius, what make/model is it and what makes that the holy grail? (not doubting, just need to be educated)
That is a White Industries eccentric hub. It allows you to convert a frame with vertical dropouts to singlespeed without need for a spring loaded chain tensioner. The chain is tensioned by rotating the elliptical axle ends in the dropouts.

Thanks! I see those are around $140 online. How does that compare with the alternative?
The only other real alternative to tension the chain on a bike with vertical dropouts is to run a chain tensioner like the one pictured below. Or as the OP did, experiment with various cogs, chainrings, and half links until you find a combination that removes most of the slack. There is no way to tension the chain using the second method.

I'm sure the Surley 'Singulator' as shown above, works nice and is a simple fix, but one of the big attractions of SS to me is the simple, uncluttered look--------adding a tensioner is going backwards, in this regard! I'd do everything I could to avoid having to use one, including looking for a different bike with horizontal drop-outs. My thoughts on the Eno hub are that I'd have to really like a frame to spend that much in order to get chain tension. No doubt, it's very cool and preserves the clean 'look', but that much $$ for a hub would be a good down-payment on a complete new SS bike! :S

I also just wanted to add----for any other first-timers out there-----with a dedicated SS ring and sprocket and careful chainline alignment, you might get by without having as tight of tension as you'd ideally like! Just try it----as I said, I've ridden bike hard for many hours now and it shows no sign of dropping the chain. Beginners luck, I guess!! Sadly, when I tried to put a cog just 1 tooth bigger on, it made it too tight.

I totally agree with ya mark. I've never used a singulator or any other similar device. Just puttin' it out there for others who might want to convert their ride to ss.

Singlespeeds are my passion. I think everyone should have at least one in the stable. The Koolaid is good--Drink it!:)

Well, as much as I didn't want to, I added this shop-built chain tensioner. I made it out of the old rear derailleur. You can actually get 2 of them out of one derailleur, but this 1/2 looks best. After thoroughly cleaning it, I bolted it to the old hanger and adjusted it to line up with my ring gear by shimming with nuts and washers as shown. Very solid-----should do the job!!
