I'm building this bike specifically for altathlons, which are long bike/run/mountain-climbing solo speed attempts and setting records in altitude, distance, and elevation gain or loss. If you're curious, here's a video of altathlon training: http://www.donbowie.com/new-video-my-idea-of-a-hard-training-day/

The purpose of the build is for aero on the long hauls (no drafting is allowed) and light weight for the long climbs- plus a little comfort for distance (often +120 miles). Feel free to chime in with comments or suggestions- always looking for more performance and reasonable weight reduction. (hopefully constructive)

Here's my current build at 6.94kgs:

Frame: Milani N107 Carbon Ultra frame size XL
Wheels: American Classic Carbon 58 Wheels (race only)
Levers: SRAM Red
Derailleur/Shifter: SRAM Red
Bar: 3T Zefiro LTD Aero
Stem: Easton EA90
Crankset: Lightning SL x 172.5
Chainring: Praxis Clover 53/39
Chain: KMC X10SL DLC
Cassette: KCNC Ti 12-27
Brakes: KCNC C7
Pedals: Speedplay Zero Ti
Headset: Cane Creek IS
Saddle: Cobb Cycling V-Flow (I ride the rivet in aero, suggestions?)
Seat Post: Milani Aero carbon
Cages: Arundel Mandible

Considerations:
1) I think I need slightly more reach, so I'm considering swapping the 110 Easton EA90 stem for a 120 Extralite UL3 - anyone use this stem? I don't want flex during my climbs.
2) This model Milani is a bit noodly up front- in part I think due to the extreme narrow tube construction combined with a fairly tall headtube. I'm wondering if an ENVE 1.0 or 2.0 fork might tighten up the flex. This is no crit bike, and I'm not charging super-tight downhill corners (er, well sometimes) but a little less flex might be good. Perhaps I need to learn a little more about trail, too. (plus, I'm coming off a super-agile BMC Race Machine, so the difference is noticeable.)
3) Hawk Racing has some great looking hubs and their bearing story is convincing. Anyone have any thoughts or experience with Hawk Racing bottom brackets and/or hubs?
4) Vanity question: Wheel decals/logos or no?

Lastly, I'm not slamming my stem. This is an endurance bike. I like my back the way it is.

Thanks for checking out my build.
Don

I like the decals, IMO they stay

I wouldn't discount it yet, if this is a proven position for you and its comfortable, keep it... But I say why not go a little lower every month or so? I don't mean to sound like a bike fitter, but you've already got what looks like a decent saddle drop so a slammed stem might be a bit extreme...

So the BMC didn't cut it for you, Mr. Bowie?

Looks like a nice build. Best of luck out there!

Do you happen to know the weight of the Zefiro bars? (without the Pi-wing and clamps)

IMO there is too much "going on" when you look at the bike... loose the decals. If you regret you can always have some custom made... and maybe have them a little more toned down (e.g. grey/black instead of red/black).

Nice build anyway... and the altathlon concept is cool :)

I'd lose those decals, definitely. Those wheels are superb though - same as Zipp 404s just with nicer hubs. I rode a pair of those for ages and really loved them.

I have no problem with the height of the bars. Being a guy that has developed arthritis in his back I have had to adopt a higher position if I want to ride. That being said, I still want the most aero and light bike I can ride. So if this is an endurance bike then a little bit higher front end will work.

The only thing that I would suggest is to try and clean up the front end. Maybe some I-Link Mini shifter cables and some I-link brake cables. You could bend them behind the bars and make it look so much cleaner. Also the rear derailleur loop can be a fair bit smaller.

Thanks. I like the BMC a lot, but the frame was too small for me. Putting it up for sale.

I weighed mine at 255 grams sans wing and hardware. The wing is easily removed. The thing looks pretty fugly but has great position and is reasonably comfy.

Bad ass vid and nice looking machine Don.

Do like!


Although...I won't lie. When I saw your user name I thought Dwayne Bowe had joined WW. Don't think we have a past or present NFL player on here :lol:

Great suggestion- thanks. I checked out the I-link cables and if they will route through the Zefiro bar they seem like a great option.

Here is what my front end looks like. Wait to you see what else I am adding to the front end. Should be more aero than anything currently available.

Not if you actually want SRAM Red to work properly it can't.

Can I just congratulate the OP on his reluctance to slam his stem! More people should ignore the urge to do this - especially not before having a proper bike fitting.
