Shimano 105 5800

Hi all,

Currently looking at upgrades for my 2013 Trek 1.5 as can't really justify a whole new bike. Been umming and arring about new wheels, but am quite tempted by the new 105 groupset (http://www.bikeradar.com/road/news/arti ... ook-40450/) to replace the Tiagra on my Trek. Reading a bit about it it seems the new 105 is effectively the same level as Ultegra a year or two ago. It's for sale (though not yet in stock) through Chain Reaction Cycles for £329 which seems like a great deal. Or would I get better value from a £329 set of wheels?

Are you still using your stock Bontrager wheels? I had those when I had my Madone 2.1 (I think they are the same wheels) and swapped them for RS80 (they are RS81 now) they made a massive difference to the ride, must faster to accelerate, corner, everything. So to answer your question, yes you would get a much bigger difference spending that cash on wheels instead of a groupset.

Not to mention, your wheels are probably not 11 speed compatible anyway? So you'd need to buy some 11 speed wheels first.

Yes, still on the stock wheels, not sure which model but assume they are the bog standard ones. Hadn't clocked the lack of 11 speed compatibility though, thanks.

Wheels will make a noticeable difference as you will probably loose weight and rolling weight combined.

However the new 105 Groupset is almost as light as the Current Ultegra - so that is also a weight loss in comparison to Tiagra- but not rolling weight. (Would also say the new 105 is closer to the current Ultegra than the older versions as the brakes and gear designs are almost identical)

Most sensible approach would be to buy a new set of wheels which nowadays will inevitably be set up with an 11-speed freehub. However the majority if not all will be supplied with the required spacer to allow you to keep your current 10-speed Tiagra drivetrain.

You will see a much more noticeable difference with new wheels than spending £320 odd on 11-speed 105 5800 - bearing in mind, as pointed out above, that you will also need new wheels to match the 11-speed cassette.

For factory built wheels this is about the best bang for your buck out there at the moment and cheaper than 11-speed 105:-

Thanks, they sound brilliant but I just can't bring myself to put that rear wheel on my bike, just don't like how the spoke are arranged... Have heard they have a lovely freewheel noise though!
