Project Q - Prototype Build

<< < (6/20) > >>

Mikku:
A bit more progress. Was hoping to get the front end sorted out this weekend but have run into some fork problems. Star nuts! ::)

More about that later. In the meantime, I shelved my plans to buy a new brake cable after I found a spare inner cable in my spares box, possibly a Jagwire but I can't remember now. I therefore went to a local mtb/road bike shop and bought a strip of Shimano outer cable in "high tech grey" - sorted! :daumenhoch:

A crackin read that. Can't wait to see it put together.

Del's work is the best - them rub on's look the mutt's nuts  :daumenhoch:

Mikku:
Thanks man! I'm getting there, though encountered a few fork and headset problems over the weekend. The first was the compression bolt, which I soon realised was the wrong one! You can see from the pics that the threads inside the steerer tube start below the actual length of the bolt! :idiot2: Thankfully the FSA headset came with a star nut, so I could use that and the FSA cap instead. :daumenhoch:

The other headache was the integrated headset bearings, both of which wouldn’t fit into the headtube cups, which was not a big surprise as the bottom cup has a little ding on it and of course, this is a prototype rather than production frame, so I wasn’t expecting it to be perfect. I therefore “massaged” the bearings in with a rubber mallet and piece of cardboard, though am still not sure about the bottom bearing. If you look at the photos, the fork crown race can still be seen. Am not sure if these forks came with a built in race or one was added, but I decided to leave that rather than try to fit the FSA one that came with the headset. Not sure if this was a good idea or not, judging from the pics. What do you think? Maybe this is the excuse I've been looking for to buy one of those Lizard Skins covers! ::)

Mikku:
One of these...

VOIVOD:
 :) Do you have the correct headset or know what size bearings the frame takes? Most are 45/45 ACB but some are 36/45 ACB.The 36 degree bearings are 0.5mm wider than the 45 degree bearings which may explain the tight fit.Your crown race also looks a bit off-is the one supplied with the headset?
