This is a project that actually started almost two years ago, but I've only just got around to posting about it. I essentially set out to make the lightest bike I possibly could, subject to 4 constraints:
Power meter
Electronic shifting
Clinchers rather than tubular
Durable parts that can actually be used in real life
Complete parts list with weights:
Frame: 2016 AX Lightness Vial Evo Ultra, size S/52 - 618g inc derailleur hanger and seat post clamp
Fork: THM Scapula CT-X - 243g
Seatpost: Ax Lightness Daedalus 320mm - 106g
Headset: AX Lightness integrated by Ceramicspeed - 48g
Shifters: Shimano Dura-Ace 9070 - 233g
Rear Derailleur: Shimano Dura-Ace 9070 with Ceramicspeed coated pulleywheels - 226g
Front Derailleur: Shimano Dura-Ace 9070 - 109g
Crankset: THM Clavicula M3 with SRM power meter spider - 459g
Chainrings: Praxis Works - 137g
Bottom Bracket: AX Lightness/Ceramicspeed - 42g
Cassette: SRAM Red 11-28 - 167g
Chain: KMC X11 SL - 239g
Brakes: THM Fibula with Lightweight pads - 168g
Brake Cables: Jagwire Road Elite Link - 71g
Saddle: Ax Lightness Phoenix - 63g
Bottle cages: Ax Lightness - 41g
Handlebars: AX Lightness Rigid 120mm stem + Schmolke TLO bar, bonded by Berk Composites - 223g
Bar Tape: Lizardskins DSP Race 1.8mm with Carbonice bar plugs - 56g
Garmin Mount: Raceware - 14g
Wheels: Lightweight Meilenstein Clincher Schwarz Edition - 1184g (527+657)
Skewers: Lightweight - 43g
Tubes: Continental Race Light - 130g
Tyres: Continental GP4000SII 23mm - 430g
Pedals: (not shown but included in total weight) Speedplay Zero Nanogram - 130g
Di2 cables, battery, parts - 112g
I have some parts that would make it lighter, but go against my condition of it being rideable and durable in the real world. For example, Seqlite titanium cassette and Fibre Lyte chainrings. These together would save about 170g. Dropping the power meter in favour of the Clavicula SE would save a further 160g.
Would love to hear your thoughts and any suggestions for improvements!
Hi, just happened onto this awesome thread this morning, I know I am almost 2 years late but I still wish to share my similar project dated December 2017.
Like MarginalChains, I also set out to make the lightest bike I possibly could, subject to 3 constraints:
Electronic shifting
Clinchers rather than tubular
Durable parts that can actually be used in real life
Complete parts list:
Frame: 2018 AX Lightness Vial Evo Ultra, size S/52
Fork: THM Scapula CT
Seatpost: Ax Lightness Europa Premium
Headset: AX Lightness integrated by Ceramicspeed
Shifters: SRAM RED eTAP
Rear Derailleur: SRAM RED eTAP
Front Derailleur: SRAM RED eTAP
Crankset: SRAM RED
Chainrings: SRAM RED 50/34
Bottom Bracket: AX Lightness/Ceramicspeed
Cassette: SRAM RED 11-32
Chain: SRAM RED
Brakes: SRAM RED
Brake Cables: SRAM RED
Saddle: Selle SMP Full Carbon
Bottle cages: CarbonWorks
Handlebars: AX Lightness Rigid 6 110mm stem + AX Lightness Ergo 4200
Bar Tape: Cinelli Cork Ribbon
Garmin Mounts: SRAM Quickview Computer Mount + Garmin Varia Seat-Post Quarter Turn Mount
Garmin Sensors: Garmin Speed Sensor 2 + Cadence Sensor 2
Wheels: AX Lightness Ultra 28C/CeramicSpeed
Skewers: AX Lightness
Tubes: Tubolito Tubo Road
Tyres: Vittoria Corsa 25c
Pedals: xpedo M-Force 8 Ti
I'd like some parts that would make it lighter, but they are too expensive for the weights saved or would mean I have to go tubular. For example, THM Fibula. These would save about 150g. Dropping the tubes in favour of tubs by going with AX Lightness Ultra 25T would save a further 360g.
Would love to hear your thoughts and any suggestions for improvements!
