Performance R-100 roadbikes? And Shimano 105 group...(9 posts)

Performance R-100 roadbikes? And Shimano 105 group...Red
Mar 13, 2001 7:23 AM
Hi all.

I'm looking at buying a "entry level" (around $1,000) roadbike. Performance bike sent me their latest membership advertisement thingy and they're showing a nice looking PB brand R-100 (I think that was the number) roadbike with the Shimano 105 group for something like 800.

So, my two questions...

Anyone have any thoughts on the PB brand of roadbikes? I'm a big fan of their components for my MTB (bars, bar ends, pedals, stem, lights, etc) but I imagine they outsource frames from someone else. Anyone know who?

And secondly, is the 105 group any good? Is it like the equiv of the LX mountain bike line? I know the Sora is the bottom end, right? Or do I have it backwards? (If 105 is the bottom end and Sora is a step up, theres something wrong, since Sora is spec'd on the $500 line of bikes.)


Oh, silly question.. are the threads on a MTB pedal the same as a road pedal? I really like my current shoes but I want to use the same SPD mountain cleat so I don't need to keep swapping them out. Can I simply buy a second set of the PB mtb pedals for the roadbike?

105 miles better than sora. It's good raceable kit, just a little heavier than the higher end stuff (Ultega and Dura-Ace). Some people have even said the shifters are better than Ultega. It's good and durable, you can't go wrong with it. Threds are the same as MTB for pedals. Can't speak about the frame/rest - anyone else?

I went straight from a 105 group to a Record 10sp. I love the Record, but am amazed at how good the 105 was. Many people find the biggest 105 problem is shifting the front under load, but you can have that problem with anything. As for weight, my body weight can change more than the Record:105 difference depending on what I had for breakfast...

Dura-Ace= XTR
Ultegra= XT
105= LX
Sora= "Deore" (with no letters)
Tiagra= STX-RC, or whatever the current model is.

There's some other road bits, older models, labeled "RSX" and "RX-100". I think these are/were one step below 105. Shimano experts, correct this if it's wrong.

I think Deore replaced STX-RC, So, maybe Tiagra = Deore/STX-RC, thus, Sora would equal ALivio? with Altus and Acera even further down the mtb food chain...

Red, I responded to a similar message on the now-defunct general message board, so I don't know if you saw that or not. For what it's worth, I purchased a Performance bike around 3 1/2 years ago, also I believe an R-100. It was made out of 853 steel with a bladed carbon fork, bladed seatpost, and Campy Mirage components. Now, obviously, this is not the same as the bike they're offering now, but I can tell you that it was a wonderful bike for around $1000, at least until it got snapped into 3 pieces by an oncoming car. Also, I understand Performance stopped making thir "own" bikes for a year or 2, so I don't even know if they're using the same framebuilders or not. But, I had a positive experience with a Performance brand bike.
Thanks guys.Red

The 105 component line seems like just what I need. As a newbie roadie, Ultrgra seems overkill, and dura-ace just isn't necessary at all. (Although I have XTR on my mtb and love it...)

I'm going to PB tonight to check out the r100. Their website claims it's AL, but the website entry is very old and outdated. I'd prefer it's steel... but for 800, I just don't know... AL is cheaper, so it's probably AL. AL wouldn't be too bad though, so only one way to find out.

Thanks for the help. :)

I bought my first new road bike and it has a 105 group. I personally do not have any experience with other higher end groups, but when the guys at the shop tried it out, they were very impressed. My only complaint was the right shifter lever tended to rattle on all but the smoothest roads. I cured this by placing a small piece of foam tape on the inside of the brake lever where the inside shifter lever contacted it. I put a fiberglass shell on my truck recently and a foam tape, that has adhesive on one side, is placed where the shell contacts the truck bed. This is what I used, but I'm sure there are other things that will work. Anyway, I'm saying this because I had heard other people complain about this rattling on their bikes and when I asked about how to get rid of it, they said it was just something you had to deal with. 500 miles later, no noise and the bikes runs great.

Brian: Got the same problem with my 105. Did you disassemble anything to put the foam tape in or just slide it up as far as it would go?
