105 groupset in black or silver

Having had Sora, Tiagra and 105 the 105 is far superior.

The black finish is very durable. Go for whatever goes best with your frame, you won't regret the upgrade.

The silver coating on the brake levers on the 105 on my winter bike has rubbed off. It's not terribly noticeable, the scratched name plates where I've fallen off a couple of times detract from the colour difference!

Personally, having built bikes up with both, I prefer Tiagra and in silver.

I've just swapped my sora for 105 on my commute bike only a week ago and really prefer it. Slicker changing plus its 10sp rather than 9sp. Hoping it will cope with next winter better than the sora which was really ropey. Sora is deffo something you cut your road cycling teeth on before upgrading. I chose black simply because my frame is predominantly black.

I went Silver when I bought one for the winter bike for this very reason....great deals to be had at Merlin

I have black 105 on my very abused winter bike, it lasts fine. The cranks will show rub, especially if you wear bulky overshoes in winter though, but its not hugely noticeable.

Go with whatever looks best with your frame!
