Questions - RX100, Shimano 600, Look vs Shimanoberny8888

Hi Everyone,

I'm a newbie and I just bought a used bike...Trek 2100, '98 and it has 105 and RX100 components.

1. How good are RX100 components in comparison to the old Ultegra Shimano 600 components? Reason I ask is that I have Shimano 600 components on another bike that I can switch over.

2. Also, I never used road pedals before. Through my research, people recommend Shimano or Look pedals. Well, I can switch to either one...but I haven't bought the shoes yet. What are the advantages and disadvantages to each type of pedal?

Please let me know.

rx-100 was essentially 105 with a polished and clear coated finish rather than painted,and it sold for a few bucks less. 105 was below 600 and 600 was below DA.

Hey Bernard,

Look pedals are by far the most common in my region. I ride on Looks and I have no complaints, although you do have to keep the cleats fresh or they'll make annoying creaking sounds. Looks take a little getting used to because you have to catch the front of the cleat on the front of the pedal to engage it. Once you get the hang of you don't give it a second thought, but there is a learning curve. The best thing about these pedals in my opinion is that my shoes feel very well connected to the pedals. The cleats are fairly large which allegedly reduces "hot spots" on your feet, but the larege cleats also make the shoes awkward to walk in because your toes are higher than your heel.

You have to be careful when you ask about "Shimano" pedals because there are actually several Shimano pedal standards:

SPD: Commonly used by MTB riders. These are very easy to clip into, as most pedals allow you to engage (clip in to either side of the pedal. SPD pedals are reasonably tolerant of dirt and grit. Steel cleats last a long time, but the interface between the pedal and cleat isn't as tight as a road pedal system so you may feel some fore/aft slop in the pedals. The small cleats are usually recessed in the sole of the shoe, making them very easy to walk in.

SPD-R: The old Shimano road pedal interface. I don't know much about these as they aren't very common in my area. In fact, I've only seen one pair in the last three years, so I can't honestly tell you much about them except to say that they're single-sided entry and I believe the cleats are made of metal.

SPD-SL: The new Shimano road pedal, a.k.a. the "Lance" pedal. These are also single-sided entry, but the cleats are much more similar to Look cleats than SPD-R. The few people I've talked to seem to like them. The general consensus is that they're similar to Looks in almost every way but aren't as prone to creaking.

If you already have a mountain bike and don't plan on getting all that serious about road riding, then you'll probably do just fine with another pair of whatever pedals you have on your MTB. This will save you the cost of another pair of shoes and you won't need to get used to a new pedal system.

On the other hand, if you want to be a hard core bonafide road rider then you'll want to give the Looks and SPD-SLs a try.

PUt your Shimano 600 stuff on the bike. 600 is old 105.

Good luck
Nope, 600 = Ultegra (nm)Chen2
