Swapping the entire groupset

It was finally time to try and swap all the parts for my groupset on my racer, a GT GTR Series 5. I like the bike and frame, but I was not happy with the drive train. I like (apparently, didn’t know that myself when I started with the road bike) to tackle uphills. But the ratio on the bike was on the heavier side, with 39/53T and 11-28T. I do not mind going slow up the slopes, but I would like to do them in one go without pauses 😛

So I bought a complete groupset to swap out all parts. I did this instead of buying the separate parts since this meant that all the components would fit together.
I’ve never really wrenched a bike before, so I had planned to send it all to the local bike shop, but figured I could try and see how much I could get done myself.
New groupset is a Shimano 105 5800, 34/50T  and 11-32T.

Swapping brake calipers

…on the bike this time.

2014-07-31 18.15.52

When I bought my racing bike I wasn’t sure if I’d like that kind of biking, so I bought a used one without knowing anything about the drivetrain.
Turned out I really liked everything about the race bike style, so I’ve traversed quite some kilometers now. Anyway, the drivetrain could use some upgrades it turned out.
It came with a 53/39 front chainset and 11-28T rear cassette, 8-Speed. Turned out this makes it quite hard to tackle the uphills.

So I bought a new, complete groupset. The 105 5800 11-Speed. 50/34 front and 11-32T rear. Now the problem is I have no idea how to swap all the parts 😛

Except for the brake calipers, they seemed easy enough and didn’t require any special tools.

A spot of paint

The two steps up to the room over the garage was looking a bit grey, though better after a good scrubbing. But still, could be better.
Found some paint I had for terrace, so it should do fine here.

Before:

A bit dull

After a layer of paint:

Muuch better

Amazing what a stroke with the paintbrush can do 🙂

New brake caliper

I recently replaced the front right caliper on the 240 as it had a broken bleeder nipple. It was leaking brake fluid, so it was due for a change.

Bleeding brakes

I didn’t have anyone else around here to apply the brake pedal for me to help with the bleeding, so I have acquired a tool that runs on compressed air that sucks the fluid out. Then it is easy to do the brakes yourself. Just be sure to check the level of the brake fluid so it does not go empty.

Went for a test drive afterwards, brakes felt good now. Was a bit more squishy before the change.
