I started fitting my new 5800 Groupset last night, as I decided to take the plunge and migrate from stock components on my 2014 Defy 1 (10 speed, 105). The 5800 stuff looks real nice. Can't believe it's £200 less than Ultegra. A £200 premium to save >300g? Sod that! The old chainrings, cassette, chain and bottom bracket needed replacing, so I figured I'd just upgrade to 11 speed and do a complete overhaul of the bike while I was at it because there's a few annoying creaks developing too. I was half tempted to order a new brooks cambium saddle but got a serious case of sticker shock, how much for a saddle?!
Last night I got to work stripping down the bike, cleaning and polishing the frame. When the cranks are off it's a great opportunity to clean all those nooks and crannies that you can't normally get to. I stripped the headset down and re-greased all the bearings. Had to pop out to B&Q to get hold of some adjustable spanners to fit the new press fit BB, greasing the hell out of it to avoid any creaking. I'm sure the BB was the source of my creaking woes. Fingers crossed!
I also fitted the new ST levers and cranks. I couldn't go any further without the rear wheel in situ. Since I don't have another 10 speed bike that will take these wheels I am going to swap out the Tiagra rear hub for the new FH-5800 which is 11 speed compatible. Fingers crossed I can reuse the same spokes in the build, otherwise that is another £20 + p+p for new spokes to talk the wife into letting me order. When eyeballing it, the flanges look a similar diameter. This will be my 7th wheel build, so hopefully I can have it done in an under an hour and get on and finish the build today. Sadly, the paint work on the frame is a bit battered, but I don't think it's worth the hassle of a respray, otherwise the bike should look and run as good as new.
