If you had the choice of either chainset, which would you choose?.
I like the easiness of the granny ring on the triple for hills, (30-11), especially with the extra kg's of the T500 over other more expensive alternatives. Although i'm getting more and more OCD over the chain noise my setup seems to be making, no matter gear im in. How noisy are your bikes?
Ive changed the chain, jockey wheels, gear hanger and aligned the derailleur and seems to make no difference. Tried different greases and oils also. My next step is to swap cassettes and chainset, either with another triple or ebaying a compact to see if the closer rings help with the noise. If i went compact would i need a short cage derailleur to go with it?
What are your thoughts and preferences for either setup?

I have a triple on my T5 and semi-compact on my Mach. No point in changing on the T5 (which was my first foray into cycling) as it is fine for commuting and winter hacking.
I don't need the granny ring for the Mach as I have 11-32t cassette on the back. I'm surrounded by gert big hills and do what it takes to make cycling pleasurable in this area.
If I buy another bike I would go for a 52/36t semi-compact again as it suits me well - I am big and powerful with a slowish cadence.

Very much a personal choice but I would suggest if you're on 8 or 9 speed stay with the triple. Many people have the misconception that you cross your chain more with a triple whereas in practice the opposite should be true. They cite duplication of ratios as a waste, but it allows the use of combinations that keep the chain straighter while a compact often forces you to choose between big/big or small/small. Think of a triple as a 'one by' with an overdrive and crawler gear for when you need them I don't know what's causing your noise, maybe the wide cassette as you don't say what rear mech you have, but I don't think changing to a compact is the answer.

Compact and not even close for me. Had triple on my red t3, then when bits started to wear changed to 10 speed compact and massively (to my surprise) better. Bigger range of years (with new cassette) than what I had and just nicer/easier to use. Would not buy another bike with triple unless touring.

Richard, your intended use is a factor. As Robert above states, for touring a triple may give you more options. I have the 520 which has a Sora 9 speed triple with the cassette going up to 25T as standard, but if I felt I needed an easier gear for hills when touring with a loaded bike, then simple enough to put on a wider range cassette.
I've not owned a double, but if I was buying another bike for road rides only and no touring, I'd probably be looking at a compact.
BTW, I don't have any noise issues or rubbing with the triple.
Scott.

I have a triple on my T3a all Shimano Claris gearing. The levers have a trim function that you nudge the lever when you hear cross chain rub to moved the front mech slighty to eliminate this. A well set up triple should work fine. I like the option of there only been an 11 teeth difference when changing between 50 and 39 chainrings which spend 90% of my riding allowing a cassette with less teeth for the low gear because of the 30 on the front which I use for the steep stuff in Derbyshire and Yorks

Semi compact 52/36 here with 10sp 11-32 on back works for me

Like the idea of a semi compact 50/36 as to push a 52 x 11 is asking a lot when I need a long downhill drag to spin 50 x 11. A 12-32 would be ideal with a 52/36 for me.

I don't know what's causing your noise, maybe the wide cassette as you don't say what rear mech you have, but I don't think changing to a compact is the answer.Β chas, if your the person I think you are I'm the one who you saved a rear hanger for last week at the giltbrook store and you suggested I bring the bike in. I have the 9 speed 11-32 cassette with a 105 rear mechanism. I've swapped back to the original sora mech and still get the same noise. Its prob just me hearing things that are normal but I'm overreacting. I'll prob drop by with the bike next week and get you guys to have a look at it to check I'm not missing something obvious.

Yes sorry I missed you I was on my break when you came in. Happy to have a look/listen if you bring it in.

I'm getting a similar noise on my T3 on the triple. I have a very limited number of gears available that don't have the noise. The T3 is the 'spare' bike and as such I don't want to spend too much time or money on it.
I'm thinking of going radical and going for a single chainset up front.

Single chainrings can be even more noisy when the chain isn't straight if they have full sized teeth rather than the shortened ones that allow easier shifting on multiple rings, you may also need a device to stop the chain coming off.

another thing to consider is the intended use. in urban commuting, I find front 39 way more useful than 34. nothing worse then having to race those pesky drivers behind cycle-box and having to relay on good start and front upshift. 39 does it without need to use FD too much.
What I did to T500 SE was to get bigger cassette (28), remove smallest front ring, buy 113mm BB. that brought chain line to ideal position, enabled use of the original FD with trim and no occasional front downshift to 30 .
