105 groupset

sirmol

I have a Spec Allez
http://www.evanscycles.com/products/spe ... e-ec030703
And have now come to a stage where i want to upgrade all to 105. What do i need to look for when search for 105? the rear mech do i need short or medium? Don't really understand the difference. I'm guessing i need a double 10 speed leaver set?
cheers for the advice

edit;
For example could i buy this;

Assuming you are going 10sp you will need:
New cassete, rear derailleur, new 10sp brake/gear levers, I assume you are not changing front derailleur and chainset.

Also you need to ensure your freewheel hub can accommodate a 10sp cassette.

I think you would probably better off save some cash, sell bike on eBay and buy a newer one with 105 but it's up too you off course.

I have an Allez and am planning to do exactly this. I've looked into it and plan to just replace the shitfters, cassette and chain. The existing RD will work fine with the 10 speed cassette so it's not essential in the first instance.

It should cost ~£110 for the pair of shifters, ~£30 for the cassette and ~£10 for the chain. I'd argue you'd end up spending a fair amount more than that if you we're to sell the bike and buy a new one.

Yes that's what i'm thinking - I quite like my frame

What's the point? If your chain and cassette is worn then fine. But why bother getting new shifters and keeping the same mechs?

Are your current mechs even 10 speed? If so then why are you upgrading... and if not then it won't work.

That's £150 you don't really need to spend and won't see any noticeable improvement from. I would just get new chain (if worn), cassette (if worn) and cables (if worn) and the shifting will improve.

Several reasons for me: I have a 2011 Allez which came with Sora 3400. I've been pretty impressed with it but the thumb shifters are annoying and mean I can't shift whilst on the drops. The lever shifters also have a really bad reach angle which requires massive hands to reach from the drops too. It's also 9 speed which isn't a major issue, but would be nice to have 10. The shifting on 3400 is also a little cumbersome and the changing chainring requires significant effort.

The mechs don't need to be 10 speed as the cable pull ratio is the same for both. Ultimately, I will replace both the front and rear mechs as well as the chaninset, but with my current budget I'm looking to break it into stages.

There should be those little rubber pads that you can put in the shifters to change the reach.

...which just leaves all the other issues!

I've upgraded the wheels and various other components, so getting a better groupset seems a sensible purchase. 105 5700 is better for a number of reasons (lighter, better shifting, no thumb shifts, under tape cable routing etc.) and at £150 for the initial change it'll be a very worthwhile upgrade.

9 speed mechs will work as long as the cassette and brifters are 10 speed.

Please don't say brifters. It's like scraping fingernails down a blackboard.

I can't bring myself to say STIs though...

I was never that impressed with my 5700 setup. 5800 may be better.
