Hello
I have a Specialized Tricross Comp (2008 I think). I would like to do some light touring and could do with changing some of my gearing for lugging up hill.
Currently it has:-
Front - FSA Gossamer (175mm) 48/34T with 105 derailleur
Rear - 12-27 Ultegra 10 speed cassette and Ultegra derailleur
What is my best option?
I believe I can put a cassette on up to 30 - so was considering a Ultegra 12-30T but would I be better off trying to change my front small chain ring to a 32 or 30 - is this possible? What about a combination of 32 front and a 11-28T rear?
The 48 front and 12 rear is fine for down hill at the moment as I'm not really a speed merchant
Thanks for any advice
Richard

Rear....27 to 30 T......that's about 11% change
Front ....34 to 30 T....that's about 12% change
Do both and bottom gear will be around 25% lower, which is noticeable, I don't think you will notice much difference if you just do one or the other.
(doesn't the "Tri" in "Tricross" stand for "triple chainset".....?

Thanks for the reply
The Tri cross's lower in the range had triples the comp has a compact
The 30 rear and 30 front would certainly get me the best ration - do you know if it is possible without changing by derailleurs?

Re: Specialized Tricross Comp
Now I think about it your possible chainring size is limited by the "bolt circle diameter"....http://sheldonbrown.com/gloss_bo-z.html#bcd
Ultegra rear mech. specs. are probably here somewhere...http://si.shimano.com/#seriesList/38....you should find the biggest sprocket your mech. is "meant" to take....however, those specs. are a bit conservative, you can often run a bigger sprocket in the real world than the specs. say.
I wouldn't splash out on an Ultegra cassette personally, it will only save you a few grams over the cheapest, and is no more durable.
(but then, I wouldn't splash out on 10 speed, either....)
