better derailleurs?

[Torvi]

Im thinking about switching from 7x2 to 9/10x2 ive been looking on groupsets and they are hella expensive and got many parts i just dont really need, so can you guys help me out completing a kit part by part or is it just not worth to upgrade stuff on my carrera and just save money for trek/giant/others bike?

I would say it's not worth doing unless you can't bear to be parted from your Carrera. It wouldn't give you much advantage over what you have now. Best sell the bike and get something which has better stuff all round.

Won't you need to change shifters too (the expensive bits), and the cassette? Possibly cranks, front mech? A full 105 set is around £300, Tiagra a bit less

 

[Torvi]

ive just been looking on 10x3 and damn... not in this life i rather save for better bike i think

 

[vickster]

Why do you need a triple? Isn't Northampton relatively flat?

 

[Torvi]

northampton maybe but im not from there, wellingborough and sorroundings has hills after hills.

Ride more

[vickster]

Up it to 20 miles every day

What Carrera did you get in the end?

the 4 miles some days is forced due to my work shift, after 12hours of hard work im not in shape for pedaling more than to home.

edit, add up 3 kg's more to the bike estimated weight due to chain lock, bottle of isotonic and stuff in saddle bag

You really dont need a drink for 4 miles each way and i leave my lock at work chained to the bike rack .

You could also just get a wider range cassette , i think the mech can handle a 28 at a push .

I just got 105 triple shifters, 105 cassette, FD & RD and a KMC chain for about £200 from http://ribblecycles.co.uk/
If its a standard 130BCD rings you could always get this
http://spacycles.co.uk/products.php?plid=m2b0s149p1141 for £27, it replaces your inner ring so it becomes the middle and you then bolt the inner ring to that, and then get a 74BCD inner ring for about a £10 to get you going, or their own triple chainset for £35 this may be a little low geared though at 28/38/48 this is 110/74BCD set so your current rings wouldn't fit (if 130BCD), but you could fit a 110BCD 50th outer if you wish, though a 48x12 gives a 105" gear, you will also be able to have a close grouped cassette which is better for cadence.
The top table is what I currently have and the lower one is what I would have.

and with a 50th outer

You could even go to a 12-25 cassette and it would still be as low as a 30x27

The combinations are endless, its just a matter of tuning the gears for how you ride, but it is a lot of money though you can transfer it to a new bike (or frame).

i appriciate all that work you put into that reply but... i dont even undearstand what you are talking to me or trying to say

@Torvi the number in the left column is the number of teeth on each of the gears on the rear the ones across the top i.e. 28/38/50 in the third row down are the teeth on the front, 28 being the smallest of three rings (if a triple) the 25 at the bottom of the first column is the number of teeth on the largest rear gear this gives the distance the rear wheel will travel in inches for one rotation of the pedals, the smaller the number of inches the easier it is to pedal, I was just showing you can get a small gear without having a really large one.
The BCD is the measurement used to determine the size of the chainrings a normal double, which I believe the Carrera uses is or was 130mm a compact double like the Virtuoso I believe is 110mm (this is why they are called compacts not because of the number of teeth) you can also get a compact triple used more in touring as you can use lower gearing on the front easier.
