In Praise of Older Road Bikes
I bought a new bike in April. Coincidentally my 14 year old 105 Rim Brake Ribble had a small issue with the crank that I didn't get around to fixing (mainly because I had a new bike I wanted to ride). After riding many thousands of kilometers on my new 105 Di2 Disc brake bike, I finally got around to riding my old bike again. I posted something similar right after I got my new bike, but I thought it's worth updating with more experience on the new bike.
OMG, the old Ribble is a good bike. To be fair, I spent the last 14 years learning how to set up the brakes and shifting correctly :-). The bike is also in very good shape. It has nice tires (only 25 mm, but running at 75 PSI, which works well on the roads around here).
Rim brakes on aluminium brake tracks in the dry are awesome. Yes, they require a bit more force than Shimano 105 disc brakes, but the braking power is sufficient and they feel nice. The force requirement is most obvious braking from the hoods, but in the drops they are so buttery smooth. You can even 1 finger brake from the drops very easily. Simano 105 disc brakes are very binary and a bit grabby. 105 rim brakes with standard Ultegra cartridges/pads have much more modulation. It's very surprising. In the wet... Yeah, disc brakes any day of the week. The old bike is going to be for nice weather :-)
Shifting on the old bike is great. Really positive feel. I find Di2 a bit "dead" in that you click an electronic button and it shifts. You aren't really connected to the shifting. With mechanical shifting, you can feel all of the tension in the system. I love the feel of the bike as the gear engages.
However, there are issues. The old 10 speed 105 gears can drop the chain pretty easily on the way down because the spring tension is very high. You learn how to do it over time, but with new Di2 (and I suspect even new mechanical) it's not something you really need to think about at all. You also need to trim the gears. That's baked into my brain by now, though.
The main "problem" is that it's just not nearly as fast as the Di2. With Di2 you can shift down 3-4 gears in a single pedal stroke. I just can't do that with my 10 speed 105. I also got into the habit of downshifting the front derailleur coming into a stop. You just need a half a pedal stroke to have it all get settled. This is not a good strategy on the 10 speed. The lack of gears is also surprisingly an issue between 25-30 km/h on a compact chainset with a 11-28 in the rear. There just aren't a lot of good options and it's awkward deciding whether or not you want ot be in the big ring. With 12 speed, you can easily just get into the big rin at 25 km/h and not even think about it. Then obviously, 28 on the back is a pretty hard gear for your granny gear :-)
Tire clearance is obviously an issue as well. Reaslistically for most bikes you are stuck at 25 or 28 mm. I think my bike could actually fit 30s (just), but you would need a pretty wide rim to make it perform well, IMHO. My new bike has 32s and they are cushy, but... at slower speeds on relatively good roads 25 is not nearly as bad as I remembered it being. I still really enjoyed my ride.
Basically, I just want to encourage people who don't have the money for the latest and greatest to think hard about picking up a good quality used road bike. If you send it to the shop and get it in very good working condition I think you will be really surprised at just how good these bikes can be. In some places in the world, rim brake bikes are going for astonishingly low prices. This is a great time to pick up a bargain. I do like my new bike and will still be riding it more than the old bike, but I'm currently thinking about some upgrades to the old bike because it's got a lot of good years left in it.
