I'd keep both of them. Try the biggest tires you can on them (or the one you keep, based on your plan). ... that's just me - selling a bike is a losing proposition, especially high end bikes.

I put some old SPD pedals on my road bike when I first got it, just because I already had them and didn't want to spend the cash on new pedals at that time. Now recently I switched to Shimano PD-A530 dual-purpose platform/SPD pedals on the road bike, and I love 'em so far. Sometimes I ride the bike on slower rides with just flip flops or whatever, but when commuting or faster rides I use my SPD shoes. I was getting sick of having to switch out the pedals all the time.

MTB pedals are great for commuting for the reason listed above...also much easier to clip into since they tend to engage on either side (unless you use a campus pedal).

I kind of have the same question as OP. I want to get a 2014 Specialized Sirrus Pro for commuting to work and my gym (both of which allows storing the bike inside within eyeshot).

That being said, I also use my bike to ride to my music lesson, run errands, meet up with friends for drinks... and I'm not sure how I feel about locking up a $3000 bike to a post, ya know?

I'm new to biking... what is the upper limit of price of a bike you would feel comfortable locking to a post while running errands or grabbing a beer. Keep in mind, I live in Austin, Tx which I think is pretty bike friendly, though I do hear about thefts a decent amount.

One more vote for just keeping both of them. None of my bikes were expensive per se, but I get a kick out of riding the "fast" bike carrying as little as possible on nice days.

(Once a week, I use the fixed-gear "commuter" to haul that week's worth of clean and dirty clothes each way.)

Or a Raleigh Sports.

Taste differs ..

My favorite feature: Rohloff hub brings up the typical price..

Just happened to snap up a bike , with, for a good deal.

& Schmidt dyno hub , & LED headlight..

way post roadie .. Bike Friday , essentially a step thru frame..

Im building a $5k cross that I plan to use for my day commute, I have two very good locks (top ABUS) and have replaced everything I can with pitlocks. If somebody steals it, I have my home insurance... Riding a good bike is a pleasure I cant describe, its my transportation vehicle and I dont plan to replace it with a car. I see $50k+ cars everywhere, whats wrong with riding in a $5k machine?

Well, I commuted on my Tarmac today... and decided to keep the Tarmac.

Actually I got jaded from all the flakers/spammers/lowballers on craigslist. After being stood up about 10 times I'm all CL'ed out. Maybe it's divine intervention...

Nah, CL is just full of flakes.

I'll second caloso, although I don't race. But I do commute from Sacramento to Davis on my Trek Domane (full carbon, Ultegra/105 mix). I'm able to secure my bike right at my desk but my $2000+ setup pales in comparison to the guys I work with and their race rides they commute with on occasion.

As I'm traversing my 15+ mile route, I routinely see nice bikes 'converted' for commuting.

I have friends who never lock their $2-$3000 bikes. Depends a bit on where you park it, how long, how visible it is, the type of traffic there, and of course the crime rate. Ride what you enjoy and if you are worried, make sure it is covered on your home owners policy.

I LOOOVE doing this. Bunnyhopping railroad tracks is also awesome. It takes a bit more hops though. I commute on 23mm tires & alum frame w/ carbon fork and stays, so it's necessary! It makes me feel like the king of the world. I always look around afterwards hoping to catch some by-passer's jaw open.
As for the OP's question, try it out and see how it feels. I do it, and seems like I'm not the only one. I really do recommend the clipless pedals with shoes though, whichever way you go.

Sorry, bunny hopping is NOT necessary just because you ride 23mm tires and have carbon whatever. Might be fun to do and all, and it's cool that you can, but it's definitely not necessary.

Just plow into potholes and train tracks then?

I didn't say potholes. Ride around those. I cross tracks on 25mm tires, alum. frame and carbon fork all day long. But I know many people who run 23's and cross them, as well. Have never, ever seen anyone ever bunny hop tracks. You still have to (and should) slow down somewhat when crossing tracks, but that's still going to be faster than hopping over them.

I commute everyday to work with my 2005 Cannondale six13 Dura Ace. I'd never lock it up outside anywhere though, it is either with me in my office or at home. I enjoy riding my six13 too much to NOT use it as a daily commuter. And the old Dura Ace has been bulletproof.

I agree that bunnyhopping is not, in the strictest sense of the word, necessary. Neither is riding no-handed or trackstanding. But all of these things are useful bike handling skills that riders can use in safe and efficient riding.

Sometimes I have come across road hazards that are too wide to ride around or traffic conditions were such that a lateral swerve would be impossible or unsafe. Sometimes I have come across road hazards that I saw too late to brake or to change my line. In those cases, the quickest, safest, most efficient move was to bunnyhop.

As I said, bunnyhopping is not strictly speaking necessary, but there is almost no downside to it and it's become such a useful part of my skillset that I can't imagine not doing it.

You made a good choice. You have a sweet bike so enjoy it. On the dry days I commute on my carbon fiber BH with ultegra and mavic SLS wheels. Not as fancy as yours, but not your typical commuter. I love commuting on that bike. It makes the commute that much more fun.

I've found that riding a few crits each year can be way, way harder on a cf bike than many years of commuting. I commute on 3 carbon fiber bikes. My "A commuter" is a 2007 carpe diem and has 20K+ of year round commuting in the wet pacific northwest. The only problem I've had is fender rub (more of a problem with crabon than metal). Make sure to tape up the frame and/or buy skinny fenders.

Amen brother! More than once I've saved my wheels with a well time hop after not noticing the pothole/crack/etc. until way too late. Sure it's not "necessary" in the same way a helmet isn't necessary. But I mean, really? Oh, and braking is wasting. So hop, don't slow down

And as for the OP's original question, it's a good choice you've made indeed. Welcome to the club

I commute on a Pinarello ROKH w/ultegra and 1320gm wheelset from revolution wheelworks, never had any problems with it in nearly 5k miles. Using continental gp 4 seasons tires for durability. My co-worker commutes on his cannondale supersix evo. We just drive in once a week to drop off fresh clothes, or during the summer a lightweight backpack to carry some fresh clothes in once or twice a week.
