I had a similar dilemma back when the first udderlet was due. I didn’t have enough space to justify lots of bikes, and I knew that money was going to be tight for a while – and riding opportunities thin.
I had:
A Commencal Meta 4
DeKerf Generation
Genesis Io
Random road bike
Here’s what I did: I sold everything. Every last bike. I’d owned the DK for over a decade, and had updated it by buying the components for a proper DeKerf disk brake mount from Chris direct, and getting Argos to do a smashing job on it. I sold it to a friend I knew would ride it lots and cherish it.
I bought a Singular Hummingbird and a pair of matching Magura Menjas – hardtail with gears, singlespeed, rigid, front sus and 26er/69er all sorted in one bike.
I bought (second hand, from a friend) an Orange Five.
My suggestion:
Keep the road bike.
Sell all of the hardtails, and buy one capable of running gears if you really need it. The Hummingbird is smashing, but out of production – although Sam has a few large frames kicking around.
I should point out that I’ve yet to run gears on the Singular. If it’s a big day out in’t hills, I take the Orange.
Hope this all helps. I know it hurts to sell a bike with significant emotional attachment, but if you’r not using the Cotic or the Specialized, sell them to someone who will use and enjoy them. Then sell the On One, ‘cos it’s pink.
one other thought: I don’t know if the Excentriker BBs do the job, but that might be one way to singlespeed the Cotic. Or get a Simple.
