Why is my Focus Izalco Max Disc so heavy?

Just got my new Izalco max disc with ultegra di2. It is all stock apart from Pro Vibe Alloy Bars, Pro Team Bartape and Pirelli Pzeros. My scales say 8.1kg but surely that isn’t right for one of the lightest disc brake frames in the world.

The frame is very light but everything else isn’t.

They aren’t super heavy components

I disagree.

Ultegra is durable, precise, and affordable. Lightweight belongs to the premier groups. I’m not 100% certain but isn’t chorus or force lighter than Ultegra making it the heaviest mid-level group?

A few grams here and there adds up quick.

Sounds about right to me. What wheels, saddle, pedals, etc? What size is your frame? UDi2 is a few hundred grams heavier than DA Di2 IIRC.

My 58cm 2017 model weighed the same. With a JRC seatpost and compression plug and a Tune Komm Vorr saddle I’ve got it down to 7.9kg. Still disappointed with the weight.

You would be correct with that statement.

The clue is in the 7th word of the title. Seriously, if you want to get a disc bike light relative to light road bikes you have to go fairly exotic on all the parts. It sounds like all your parts are mid-level, except maybe the frame and fork.

Hydraulic disc brakes have a weight penalty. Shimano more so than others.

Only the shifters are almost twice as heavy as Sram Red mechanical shifters (rim brake).

What about your wheelset?

There is hope yet. You could start shaving the weight and maybe arrive at 7kg.

To be fair, Shimano's Di2 Hydraulic snifters are indeed much lighter than eTap HRD shifters.

What ⬆️ They say...all true

Nevertheless I think they're a great bike

Frame light...my 56cm disc frame was 800ish grams...

With dura ace, new saddle, seat Post, handle bar, stem, expander and 1500g wheels mine weighs 7.1ish...need to update build photos

Waiting on tubular wheels to be delivered hoping for 6.7-6.8kg

Low 6kg disc bikes are possible but bloody expensive

Or high 5kg but even more $

Well, that's "simple" to fix: change everything besides frameset, shifters and calipers, you should be able to get into high-5kg easily.

Sorry @Klaster_1...should have linked your bike...it's one of the lightest disk bikes on here

You're right. Only 360gr per pair for r8070 shifters.

Where did I see 500+ gr for hydraulic shifters? Maybe ultegra non-di2 hydraulic? I forgot...

Anyway. Don't give up. You can improve the bike.

All non-series Shimano hydro shifters are over 500g, including ST-RS685 (~646g) and ST-R785 (~510g).
