Basically last year's ultegra. It shifts beautifully, brakes in a way that really inspires confidence on long descents and looks great too. I like the feel of the hoods, they feel solid and are confortable. As an entire package the 105 group works together flawlessly, and for a price that's unbeatable.

Excellent offer on a fantastic group set. Was looking to upgrade my 20 year old components, which worked fine until my rear wheel collapsed requiring a custom rebuild in order to still be compatible with my antiquated setup. I could not find anything which came close to this in terms of quality and price. Not only recommended, I would buy it again if I had a second bike to outfit.

In a word - excellent. I installed this new 105 groupset on my 2011 Trek 1.5 as an upgrade from a mismatched factory group. I could not be more pleased by Merlin's packing and shipping of the group. With the proper tools, removal of the old and installing the new 11 speed 105 group was easy. Please make sure you check with Merlin to be sure your freehub body can fit an 11 speed cassette. In terms of ride quality and improvement from my prior setup, it feels so incredibly efficient and makes riding much, much better. I would highly recommend this as an upgrade from a lesser factory groupset on any bike!

Great groupset, shifts really well, I have ultegra on another bike and really can't tell the difference, very smooth actions. Highly recommended if you want to slap a set of decent gears on a winter bike.

I am not given to hyperbole but this groupset has transformed my bike. The shifting is slick and the brakes will almost stop:-)you on a sixpence. I upgraded from 105 5600 and the hoods are slightly longer so I had to adjust the rotation of the handlebars to regain a comfortable position. I just want to go out and ride my bike all the time since fitting it.
If you need a new groupset put this on your wish list.

Brilliant groupset. I have Dura Ace 9000 on another bike and this compares very well - levers are the same shape, gear changes almost exactly the same quality and brakes are very strong and with progressive lever feel. The chainset is ideal for a stealth build - looks great with a kind of matt finish as opposed to the cheap shiny black of 5700.
I was very well looked after by Merlin for this purchase - win, win!

Required a new groupset for by winter bike frame, 105 is the perfect choice for a winter bike after using the 5700 groupset which is reliable and cheap. I opened the box but surprised to find no instructions for the fitting and tweaking of the individual parts, you have to download these from shimano`s dealers fitting instructions when printed of took half a ream of paper with lots of irrelevant stuff. But you DO require these instructions as there are aspects of fitting the front derailleur, sti's and cables that are different from the 5700 groupset. The 5800 groupset works well with very smooth shifting, although the brake calipers are a little disappointing, I expected a little more power after reading about the upgrades, nowhere near as powerful as my Sram force calipers, they will be the only upgrade I will make in the future. The only susceptible difference between the 5700 and 5800 is a slightly smoother gear change 11 speed is not noticeable, and so if the 5700 was significantly cheaper I would recommend to buy that, but in fact you can buy 5800 cheaper so buy it if you require a cheap reliable high performance groupset that is also better looking than the previous model. Just remember to order paper and a new ink cartridge with your order.

Upgrade from Sora 9 speed, triple crank. Fantastic. Shifting feels very precise and smooth, it seems to hold up and not need adjusting as often. Double compact with 11 (11-28) speed is giving me the range I need, flats, descents and hill climbs. Braking is amazing - doesn't require as much effort but still strong and responsive. Merlin delivery nice and fast. Will use again.
