I had eebrakes on two of my bikes, the center mount version, not the direct mount version... and there was no maintenance required in probably 7 years.. other than changing pads, which is super easy on them.
Good to hear it. I've read many posts from people saying the same, but also just as many posts from people saying DA direct mount brakes are superior in every other way other than weight.
It's a moot point at this point anyways as I'm realising I'm not only going to have to have a machinist make the adaptor for me. I also might have to source some SL6 Tarmac specific rear eeBrake calipers. Trust me though. I've wanted a set of eeBrakes for so many years now I couldn't care less for their braking power, or how fidly they might be to install or maintain. Nothing anyone can say could put me off them as I put them at the very top above all other weight weenie parts on the market.
PS: I've gone and done something I never do, and that's to calculate what the end weight might be. I'm terrible at math (I failed math in school lol) and I've never in my life created a spreadsheet (never will either!), so with all my builds to date it's been more of a natural progression of trial and error and going with the flow vs. planning an entire build out before buying anything.
When I first weighed the bike in at 7.47kg I knew it wouldn't take too much to get the bike into the high 6kg mark. In my mind I was going to be happy with that, but after doing some calculations using weights listed by manufacturers and deducting parts I've yet to receive from the parts I've ripping off I've come up with this:
Frame: 2018 Specialized S-WORKS Size 52
Seatpost: Hylix (117g)
Saddle: Berk Lipa short padded (85g)
Stem: Extralite Hyperstem Stealth 120mm 6 degree (87g)
Bars: ENVE Aero IN-Route (267g)
Bar Tape: EXS Airtape (30g)
Front Derailleur: SRAM Red eTap
Rear Derailleur: SRAM Red eTap short cage (228g)
Cranks: Sram Red 167.5 50/34 (539g)
Brakes: Campagnolo Direct (352g)
Pedals: Xpedo Thrust SL Titanium (165g)
Bottle Cage: CarbonWorks (9g)
Wheelset: Wheelsfar Feder 45mm Extralite hubs cx-Super spokes (1280g)
Cassette: ZTTO SLR Gen3 11 Speed 11-28 (113g)
QR Skewers: Condor Ti (45g)
Tyres: Panaracer Agilest Light 25mm (340g)
Tubes: RideNow TPU Road Light (72g)
5.99kg?!
That's pretty wild (to me!). I would have been super happy with low 6kg's fully loaded, but if I can get into the high 5kg's I'll jump up and down on my couch like Tom Cruise.
The ENVE bars are heavy. Cadex Race Handlebars in 380mm weigh 154g, that -113g. Dura Ace brake calipers would save another -40g. Not sure where else I could save weight, maybe a lighter chain? Either way it's looking like my goal has shifted now from a high 6kg's build to a high 5kg's build (I'm excited!).
