Thought I'd post this here, will cross post in the Fixed Gear Forum too:

Why?, because I could. Mostly for giggles and to get me motivated to ride my Tri bike more.

Had an eccenric hub made for me, it allows the use of vertical drop outs by rotating back and then locking down. This gives you room enough to get the chain on and then take up the slack. I left the front derailleur on as a guide and to ease the conversion back gears come race season. Hub and wheel build was under $200, good to have buddies :thumb:

I'll likely get an old Velocity Deep V front wheel I have lying around rebuild to match the rear wheel too. For now my trusty training wheel is fine. The bike mostly sees duty on the CompuTrainer this time of year anyways.

Running 50x17 in the Pic (that's about 71 gear inches). I normally have a 55t front ring and will put that back on now and then when I'm riding flatter routes come spring and summer. Plan on dong a local sprint Tri this way too. My only A race is IM Cozumel this season, so I need to watch burn out and keep things fun. I've only done one brief ride on it, feels great. Totally silent driveline. I have a regular road fixie too, so riding fixed on the road is nothing new to me.

It all ready has the wife asking me things along the lines of, so you'll end up leaving that and get a new Tri frame, won't you?

It may just serve a greater purpose!

I figure I'll do a bunch of trainer and a bit of road time on it like this and then flip it back once the season is in full swing. I'm only focusing on IM Cozumel this year, so I have till Nov before my "A" race. It'll be fun to a do a sprint or two like this (with a bit higher gear) too.

Be careful...if you leave two bicycles in the same room, they WILL multiply!!! The six in my garage are testimony to this fact (2 Roadies, 1 Tri Bike, 1 Fixed Gear, 1 Mountain Bike, & 1 1960's dumpster recovery that will likely become a fixed gear)

Yes they do, I have a road, that tri bike, fixie, cyclocross and a MTB myself. Wife has a tri and cross bike.
