As we stand, 7.5kg.
I had it down to 7.15kg at one point. But have since swapped out to bigger tires, bigger chainrings, and a longer, heavier cockpit. The frame is pretty light for the 10R frameset at 943g. I briefly, and I mean briefly, considered an S-Works upgrade but $5500 to save 75g seemed excessive and I felt I could better spend my money elsewhere.
Areas of consideration
- seatpost: currently 193g, stock seatpost. Darimo is a good option and would save ~60-70g. Cost: ~$350. I'd probably go with the non-Di2 model to save weight and relocate the charging port to the handlebars. Another option (albeit sketchy) is the AliExpress copy. Slightly heavier, substantially cheaper at around $50. But I'm not sure I trust it, and I don't see longer lengths.
- cockpit: Black Inc bar/stem, weighing in at 337g for 120mm/40cm. A lot lighter than the Tarmac stem/Aerofly combo (180g/232g), and more importantly, more comfortable. I had the Alpinist cockpit on there for a bit but wanted narrower bars, and they don't offer the sizing I want. Looking at the Pro Vibe Superlight cockpit (~150g bar, ~120g stem). I don't want a super aero bar, I don't find them comfortable at all and I ride on the tops a lot. The Black Inc is actually the most comfortable bar I've used. It's slightly oval and fits my hands well. The MCFK bar is another option around 150g and has a nice backsweep. For stems, I know there are some lighter options but unsure how they'd look on the SL7. Comfort is the priority here, so if I can't find a lighter option that is comfortable and looks good, I might just stick with what I have.
- wheels: currently running Light Bicycle AR45 (flyweight front, standard rear), which came in at 1,426g for the set. Craft Racing Wheels look good at around $1,680 and weighing 1,190g, which would be a substantial weight savings. Not sure there are lighter options for that price. For rotors I'm already running Galfer 160/140, weighing 96g/79g. Cassette is a SRAM Red 1190 11-32t, which weighs 196g. I climb a lot so I'm not going any smaller, and this cassette is superlight already. Tires are GP5000 Tubeless (not the S). They're fairly heavy at 289g/296g. Plus sealant. I'm looking at GP5000 clinchers (~221g each according to BRR), plus TPU tubes at 25g each, so around 90g savings. So overall, could save around 300g total on the wheelset.
- cages: Supacaz carbon weigh 22g each. I have some AliEx carbon cages that weigh 7g each I'm going to throw on.
- cranks/pedals: Dura-Ace cranks weighing 635g. Assioma Duo weigh 303g. Could go to SRAM Red cranks and Quarq PM and save some grams and keep the chainrings. But I really like the Assiomas. Rotor Aldu Carbon are another option.
- group set: mostly Ultegra 11-sp Di2. Not sure f going to 12-sp would be saving weight. Could swap out derailleurs but hard to justify upgrading those and staying 11-sp. Going to 12-sp would mean a heavier cassette and unless I went Dura-Ace, I think the Ultegra group is heavier.
Will be posting pics as I get new parts. And will weigh new part against old to see what I'm losing.
The next part is just about my personal weight journey so if you just care about the bike, you can stop here. My own weight has fluctuated wildly since high school. As a senior, I was a string bean at 6'3" (189cm), weighing in at 160lbs (73kg) soaking wet. And I was told by every sports coach that I'd need to gain weight if I wanted to continue playing in college. So I did. By the start of my freshman year of college I had bulked up to 210lbs so I could play football, and hit 220lbs by the next year, solid linebacker build. But after college I started doing more 12oz curls and less actual curls, and dropped down to 210lbs but also lost all of the muscle. I looked at myself in a picture and was embarrassed at what I had morphed into. So I started exercising again and stopped drinking, and within 6 months had dropped down to 175lbs (80kg), my lowest weight since high school. And a weight I felt happy and healthy at. But since then, work and Covid has facilitated some weight gain, and I'm back up to 195lbs (89kg). So I'm ready to drop the pounds on my body and grams on my bike. Because as fun as it is to tinker with my bike and drop some grams, I know the real weight loss comes off the bike. Goal weight is around 175-180lbs, so around 80-82kg.
