    Smile My Niner A9C SS

    Here is a picture and a quick review of my new Niner A9C.

    My Niner A9C SS-img_1512-1.jpg

    Frame/Fork
    • Frame Niner Air Carbon Large
    • Fork Niner Carbon Fork

    Wheels
    • Rim Crest
    • Hubs Hope 2 Trial/SS
    • DT Revolution Spokes
    • Tires Schwalbe Racing Ralf 2.4 (Front - 19psi) & 2.25 (Rear- 24psi)

    Cockpit
    • Handlebar Ritchey SuperLogic Rizer Carbon
    • Stem Ritchey WCS
    • Grip Ergon GP1 Leichtbau
    • Saddle Selle Italia SLR
    • Seat Post Ritchey WCS Carbon One-Bolt Zero Offset

    Drive Train
    • Crank X0
    • HBC 28t Ti Chainring
    • HBC 16t Ti Cog
    • Pedals CB Egg Beater 3
    • Brakes Formula R1

    Weight: ~18lbs.

    Although it sounds like a full WW build, I did not want to sacrifice comfort (RR2.4, Crest instead of Race rims, Ergon Grips)
    I am 5'11", 150lbs. I ride a lot, and race a little. I have about 200 miles on it so far, riding North Texas trails. I also have a Niner Jet. I also owned in the past a Stumpjumper FSR, an Ibis Mojo and a Fisher Rig.

    The good:
    • Amazing acceleration
    • Incredible climbing
    • Great cornering
    • Effortless spinning
    • Silent (except when coasting...)

    The bad:
    I am still not sure on the rigid fork. It is really, really great 98% of the time, but the remaining 2% is painful and I have to slow down (rocks, logs, roots). I will continue to ride another 200 miles before making the final call. If I wouldn't race, I would definitely keep it rigid. I am worried about losing the "magic" feel with going with a suspension fork.

    I still need to cut the fork steerer, and add a red spacer if any needed. The brake hoses look a little long.

    Other comments
    • The R1 brakes are the best brakes I have ever had. Great feel and look. And it finally converted me to use a single finger (better lever ergonomic for my fingers).
    • I really like the Crest rims so far. The added width compared to my 355s appears noticeable (or placebo effect).
    • The Hope SS hubs are loud (as expected), and they sound quite different than the regular ones. I like it so far, except when I need to talk to someone while costing
    • This SLR saddle is quite comfortable (I have had many SLRs in the past, first time with the Flow version)
    • The Racing Ralph are excellent as usual for me. The large 2.4 up front does a great job taking care of the chatter. Rolls fast and corners well
    • The HBC cog and chainring are very nicely machined. I wanted to keep the chainring as small as possible for clearance (we have many logs around here).
    • The EBB has been completely silent so far

    I have an SIR9 SS with the same fork and it does take some getting used to, now I barely notice it except on the rockiest downhills an some really rocky uphills where I could use the cush to keep my line. I definitely noticed my upper body strength improve with it and as time goes on it does get easier.

    The bike has been great. I love it. Made a few changes along the way.

    I put a Reba XX fork. I loved the feeling of the rigid, but for some racing, it was slowing me down on the roots.

    I also put a new RDO seatpost. I needed to buy a new one for my road bike, so I moved the Richey over.

    The bike puts such a smile on my face when I ride it.

    It still looks like new, despite lots of riding and some endurance racing.

    It's in the first post -- 18lbs.

    Unless you're talking about the new set up with the Reba. Then, I guess it would be 1.5-2lbs heavier.

    These are some of the finest looking bikes on the market IMO. Starting to see more and more of them. Great job/choice.

    Well first of all he said that already. And second of all, don't you think he probably knows that seeing as he built the bike himself? How astute

    The routing on the front brake hose looks weird. The way you routed it, the hose may rub on the tire.

    A few responses:
    - I wanted to wait before cutting the steerer to see if I liked the rigid front (was my first try). It is cut flush on my Reba XX
    - The weight is now a hair under 20lbs with the Reba and RDO seatpost. Weight was not the priority for this build. If you want to see a light A9C SS, see Mattkock's bike (5-6 lbs lighter?)
    - The front brake hose is routed more traditionally on my new setup with the Reba

    BTW, for those of you interested in running a small chainring up front, if I were to do it again, I would go slightly larger. If the chain becomes loose a little, it will slap on the chainstay, ruining the blissful experience of riding a totally silent bike.

    Did I tell you I love this bike?

    I waited a couple of weeks for the chainring. But that was in March last year. Was happy with HBC.

    Very clean build, hbc on those cranks makes for a very sleek look. What are your thoughts on those brakes after nearly a year?

    The R1s are my favorite brakes. The feel, power and look are great. I recently got thew new Race XTRs on another bike. I also really like them, but the power is not the same. Note sure if my pads/rotors got contaminated.

    We have the new XTR's and XT's on most of our bikes and we could not be happier. I will say that I did have a set of pads that did get oil on them and they were toasted, worth swapping pads.

    I need to order in a set of the formulas to play around with.
