Bottom bracket - swap advice needed
A little bit of advice for the less technically minded please.
I currently own a Bianchi Via Nirone 7 Tiagra 2010, spec via the Evans website:
I've recently sold my commuter (the Bianchi is the "nice" bike) & I plan to replace it with a Ribble Special Edition. Initially, I was committed to the Tiagra special edition for £579. I've noted however that you can get the special edition fitted out with either Sram Rival or 105 for £738(ish). My plan is to spend the extra to get the fancier groupset in order to swap it onto my Bianchi frame - effectively delivering a full groupset upgrade to the Bianchi for £159 whilst still getting a Tiagra equipped Winter (the Bianchi groupset is in good order)
I'm leaning towards Sram Rival over 105, purely on novelty grounds.
I'm comfortable switching deraillers, cassettes and shifters. Where I have no experience however is in the bottom bracket department.
Could a kind soul advise?
Here's the Bianchi as stock:
Here's the Winter Trainer:
or the Winter Trainer frame only (if that helps?)
1. What tools do I need to tackle the bottom brackets?
2. Can the Bianchi & SRAM bottom brackets be switched, or will I have to buy new? The Bianchi's bottom bracket appears to be completely internal, whereas SRAM is using external bearings (i.e is there a frame compatibility issue?)
3. Are there any other issues to consider / is this a bad idea?
4. Should I go for SRAM Apex (saving £70) or is it a case of once you've committed to buying the tools you may as well go all out?
