2012 Specialized Sirrus: A Commuter Bike

It’s been a while since I’ve ridden my Sirrus. Not because I don’t like it but because I now have the Roubaix as my primary ride. For a long time, the Sirrus sat in the shop with the wheels removed waiting for new rubber to be put on them. Pretty much just collecting dust. What a shame. I’ve always wanted to convert it to a commuter bike so I could ride to work on casual Fridays, but I always put it off. Well not anymore! This month I got the ball rolling on making the Sirrus a good commuter bike and this is what I came up with.

First of all it needed new tires so off to my LBS and picked up some Continental 4000S II. I love these tires. They have a good balance between low rolling and puncture resistance plus long life to boot. For the rear I used 25 mm and 23 mm for the front. It’s the same setup on the Roubaix.

After a good wash and lube I went out for a quick spin around the block to check things out. No issues. Brakes and shifting were great, just as I remembered it!

For the pedals I left them as is. They were the Shimano A530 SPD pedals and since they had a platform side I figured I could use them and not have to worry about hauling a pair of regular shoes when I commute. At least that was the idea.

Next, I needed a rack for the bike. I didn’t want to do that song and dance of taking a change of clothes the day before and pick them up the day after (or in this case on Monday). I wanted to be able to haul my clothes with me to and from work. For that a rack is needed. This posed a problem for me because the 2012 Sirrus didn’t have any eyelets to mount a rack. A coworker suggested to look at Old Man Mountain for a rack. Sure enough there was one designed for bikes like mine. The Black Rock rack was suggested for bikes with out eyelets. After emailing them and asking specifically about using it for the Sirrus they assured me that it will work fine and told me where on the seat stay to mount the clamps.

Sirrus_MountThe Black Rock rack is designed to mount on the outside of the hub dropouts. They also provide a longer skewer for you to use to clamp it down. The bulk of the weight that it supports is supported there at the hub. The attachment to the seat stay is needed to position the rack horizontally and hold it there. The loop clamps that attach to the seat stay are coated so that they will not scratch the bike and they are contoured so that it is not squeezing on the frame. Once completed I again went out for another spin. Solid! No rattles of any kind.

Sirrus_Rack_InstallWith the rack in place I now needed some panniers for it. Another trip to my LBS and I came home with something to try out. Not the most expensive one nor biggest but something to put in my clothes and zip it up. I wasn’t sure how big they needed to be in order to take a change of clothes. I would have to stuff it and see if it can hold it all. That was the first thing I did when I got home. Doing this made me think as to what I had to take with me and how to pack it. Not only do I need clothes but I also need wipes (to clean up when I get there), deodorant, tire pump, my keg (holds spare tube, patches, tire levers and some cash) and my iPad. After I gathered up everything I proceeded to pack. Yes! Everything fits with room to spare.

Knowing that I got the right size bag, I went ahead and installed it on the rack. Installation is straightforward with hooks on each side that clamps to the bottom of the rack. As usual I took it out for a spin to check it out. Uh oh. Problem. The back of my feet hits the corner of the bag on the up stroke. Yikes, I don’t want that.

After doing some research I found out that you should try to get panniers that are tapered on the front so that your feet won’t hit the bag (you can also tilt the rack back a little). I looked at mine and they were the squarish type. Time to take them back and look for something else. Luckily a different LBS had the kind I was looking for so I got them. After installing them and going out for another spin, all was good. I’m ready to go.

Friday’s ride to work was good. The road was a little wet from the night showers but I didn’t get rained on going or coming back from work. The 14 mile ride was a lot faster than I thought it would be. The last half of the ride I was pushing 18 mph easily. It must have been the wet roads or the thrill of cycling to work because it was a different story going home. Going home was a lot harder but enjoyable once I changed my mindset that this is not a race.

Some lessons learned from this one ride. Fenders. I need fenders for the wet roads. Either that or I don’t ride on wet roads. Finding fenders for this type of bike is going to be difficult since it has no eyelets for them either. I think I’ll go with the option of not riding on wet roads until I can find a system of mounting some sort of fenders. Around here that is not a high priority so it can wait.

Sirrus_PedalsThe other issue I had was the pedals. I always had to flip them around to get the flat side up plus my shoe slips while cycling. I’m constantly readjusting my feet position as I ride for a bit. New pedals are in order. Checking Amazon I see a lot to choose from and I see that the majority have those pins on them. I remembered that the LBS had some pedals like that so I went to check them out. Sure enough they had the Specialized Bennies Platform pedals, also in red. Perfect.

Sirrus_TargetMy next ride was out to Target to pick up some groceries. It’s been raining a lot recently so I had to wait for the right day to do it. The trip was 4.5 miles one-way and the pedals were rock solid. No slippage and stuck to my shoes like glue.

One aspect of the bike was the use of lights. Riding to work starts early morning and I need lights to see and be visible. My front light is the same one I use on the Roubaix, the CygoLite TridenX. Super bright and can easily moved from bike to bike. For the rear I also reuse the same light on my Roubaix. It has a nice band strap that I can take off and move to another bike. I also had two ankle cycling lights that I’ve got from several charity rides. I put one on my left ankle and the other strapped to the top of the panniers. One last set of lights are the spoke lights from Nite Ize See’Ems (Yes that’s the what they call them). They add visibility from the side. I’m basically all lit up for night riding.

Can you convert a 2012 Sirrus Limited to a commuter bike complete with panniers? I showed that you can sans the fenders. Doing this modification was a fun, learning experience for me. I’m still looking to find a way to add fenders for those days that the roads are wet and I’m sure I’ll figure out something. Now that it is done, the bike will see a lot more use with trips to work, groceries and social rides with friends to local markets.
