Next items on the agenda are
- hook up the hydraulic lines to the brake levers
- bleed brakes
- center the rotors
- install Favero Assioma duo power meter pedals
- wrap handlebars
- pump up tires
Brake Lines: I ran the brake lines from the calipers to the handlebars. Since one needs special tools (funnel, hydraulic hose cutter, brake bleed kit, brake fluid, etc.), this things would be a lot more expensive to purchase than just taking the bike to a local bike shop, especially one that owes me a favor 😊.
Due to health safety precautions, I had to wait outside the bike shop. After waiting about 15 minutes, they rolled the bike back out to me, everything hooked up. This takes care of #1, #2 above.
To center the calipers, just loosen the caliper mounting bolts, squeeze the brake lever and retighten.
Next, the pedals. Easy install, but make sure you don’t (a) cross-thread the pedal axle bolt or (b) turn the wrong way. Remember, one side is reverse threaded.
Last item, handlebar tape. I have 4 choices:
So, which color combination would look best?
Conclusions, Observations, Lessons Learned
- If you are going to build a bike and you are not a professional mechanic, or you don’t work at a bike shop or you don’t have ready access to lots of (Shimano) parts, don’t build a disc-brake bike.
There are so many bolt length issues based on which disc-brakes you choose, frame design, tube thicknesses, etc. that you need 4 of each length bolts. A rim brake bike is much easier to put together.
- Also, unless you are versed in running, hooking-up and bleeding hydraulic lines, have a real mechanic do it for you. A non-hydraulic rim brake bike is much easier to put together.
- Hydraulic systems take much more work to put together, as well as maintain. For example, one manual says to include a 2.5mm aluminum washer on the rear caliper bolt and shows it in their diagram. Another installation manual supplied with the brakes does not mention them nor does it show them being installed.
My guess is that if you called Shimano tech support, and talked with 6 technicians, 3 would say you need them the other 3 would say you don’t. So, which is it?
- I was lucky to already have many of the parts needed, bars, saddle, seat post, wheels, dura-ace rotors, crankset, pedals which saved a ton of money. Be prepared for sticker-shock if you want to put together a higher-end disc bike.
But, all-in-all, I think it came out and looks pretty good! What do you think?
