Shimano 105 R7000

A difference is just the overall shape of the caliper, so that shouldn't put you off beyond weight and a very slight difference in feel. There is now ...

It's good weight, good performance, durability, great ergonomics. It's really all group set that anybody needs, but those are my thoughts and opinions...

My opinion is that the current 105 has nicer shifting than Dura Ace from ten years go. 7900 wasn't great. 9000 was an improvement, but 9100 is king. R8000 Ultegra and R7000 105 were the 'trickle down' and just as good with slightly less fancy materials and a few extra grams.

Yes. That's a great price. The Reacto 400 is normally specced with high to mid-range components such as Shimano 105. I believe this is a 2018 model year frame.

Sometimes I can get it there when I’m riding by back pedalling and jerking the chain, but that’s it. Not really sure why this suddenly started happening. For reference, it is a Shimano 105 R7000 group set, I take decent care of it, the cables have never been replaced and it has done about 7,200 km in it’s life so far. I have never touched the limit screws either.

I would choose the Merida since it appears to have Shimano 105 R7000, based on what I can tell from the photo. The difference between Shimano Sora and Shimano 105 is well worth $400.

For 4700 AUD this is a very good deal, the main selling point of this bike would be the frame in my opinion. I don't think it is neccesary to get a bike with an expensive Di2 groupset, mechanical works just fine as well. The 105 mechanical groupset is also of very good quality, I had it on my previous bike and I experienced no problems with it at all.

105 is definitely an upgrade over Tiagra, particularly in the current offering. 105 R7000 is actually very close to ultegra R8000 in design and function, only a little heavier because of material choice. On the other hand, there is nothing wrong with Tiagra, I did 2 HIMs on Tiagra and did just fine! Particularly if you are getting started, the advantages of 105 would not be something you would miss.

I love the bike. It is firmly build and has basic technology (rim brakes, cables outside the drone, Shimano 105). With a little bit adjusting, and packing very light, I think I could manage all my luggage on it (front fork bags, handle bar bag, top tube bag and saddle bag). The only thing that I’m a bit worried is the tire width; I think 25 mm is the maximum that I can get on it.

Bike serviced. Lizzardskins low impact handlebar tape. 1 water bottle bolt missing. standard scratches otherwise in very Good.
