Now here's a newbie question. I've not built a new bike since around 1990, so am unsure, but how do I know that if I buy a new groupset it will fit my bike?
Do frames have standard bottom bracket sizing? I guess I'd need to go for clip on rather than braze on, or get the LBS to install the new groupset.
While the present groupset on my bike is old, the frame itself is ok for probably another year for me. I figure the best thing to do would be to upgrade the groupset now, and then purchase a new F+F and wheels, saddle, etc down the track. Is this a good option? I broached the subject this morning with the Mrs, and she was much happier with that option. I figure it will also get me a much better bike for the same dollars.
One of the links posted above:
Sora shifters - 129 Great Britain Pounds
Sora 9sp groupset - 179 GBP
It seems like I'd be a mug not to spend the extra 50 pounds and get the whole lot at once.
Alternatively, and this is probably a flame bringing question - Campagnolo or Shimano?
Ribble, posted above, has a Campagnolo Xenon/Mirage 10sp groupset for 230GBP......
Cheers,

Since I sent you down this line, I'd better keep offering you "words of wisdom" (or otherwise - you decide!) ...
I'll also declare my bias - I'm a Campag fan and Campag user from way back. I have however used Shimano, most recently on my cross bike for the last 9 months.
Ok, with that out of the way ... I'll say the following:
- steer away from Sora - it's very much a bottom of the range group set. If you were going to commute 5km each way to work a couple of times a week, it's fine. But anything more than that and you'll get really frustrated with it. An ex-girlfriend of mine had it on her bike when she started training for Ironman - but by the time she was doing the event, she had bought a new bike with Ultegra on it, mainly prompted by her frustration with the Sora.
- Tiagra is an OK gruppo. From your OP, I'd say that you'd be happy with that groupo and you may not notice the benefits of the higher groups at this stage. This was what was on my cross bike (I recently changed to Veloce) and it worked OK - nothing stellar, but it handled mud, crashes and a winter of riding in the snow over here.
- the Xenon/Mirage group is a good gruppo. One thing that Campag do much better than Shimano is to move their top line technology down the model lines (Shimano put "adaptations" of the top gruppos into the cheaper ones). So what you're getting with this set up is something that is similar to a Record set of a few years ago. To my mind, this is a better option than Tiagra - but, as I say, I'm a Campag fan.
- if the Minister of Finance will allow, I'd actually spend the extra GBP85 (bearing in mind that their prices still include VAT, which you get back as an "export customer" - but I always used the VAT inclusive price as a proxy for a landed price) and get the Veloce Ultrashift gruppo. The reason why I say this is that the technology in the levers and the Ultra-torque crank are right up there. Basically, in each case you are buying exactly the same as the current Super Record (just not carbon and not 11 speed). The shifting is fantastic - even better than the Record from a couple of years back that I have on my road bike!
Part of my reason for recommending Campag is the comment that another poster made to you - "Shimano wears out, Campag wears in". It is legendary for its durability. Also, if you do have a problem, spares are available at generally reasonable prices to mere mortals like us - only pro teams get most of the Shimano spares.
So, yeah, if I was ranking the options, I'd go Veloce Ultrashift, Xenon/Mirage and Tiagra ... That said, you have to go with what feels most comfortable of the three of those.
As for your questions about the gruppo fitting - should be no problem. Just make sure that you get the threading on the bottom bracket right - English (most common) or Italian. You can tell by the TPI count on the bracket cups.
The only other area of possible concern would be your rear dropout width/spacing - but RSX is the same width as the modern gruppos, so you'll have no problems with that.
Just thinking - make sure you check the seat tube circumference on your frame for when you specify the size of the front derailleur band. Most modern frames are either 31.8 or 34 - if you've got an older steel frame, you'll be less than this. No hassles though, all you need to do is get a bit of rubber (eg., like the spacers that you get with light sets to make sure that the mount fits your handlebars) and put that under the band. I did this recently for a friend who took a derailleur off me for his old steel framed roadie - and it works fine.
Lastly, good on you for going this way - custom building I mean. You can end up spending a little more than you otherwise would, but you know that you're getting something that you really want and that you have chosen. Be careful though, once you start down this line, you'll never want an off the shelf bike again!
Hope all of that is of some help. Feel free to PM me if you've got any specific questions that you think I could help with.
