Do you reckon they'll get the weight down for 2021 model and if so how light will it be?
Can't weight for semi-aero disc brake bikes closing in on 6kg.
During the past four weeks, I was shopping for a new roadbike.
Since I ride a Canyon Aeroad already, the new Venge did not make sense in my stable as a second aero bike.
Instead, I wanted more of a complimentary bike, i.e. a mountain goat for climbing.
However, I'd take the weight penalty for disc brakes. I ride in the alps and dislike the unpredictable braking behaviour of carbon rim brakes in the wet.
Goal: achieve sub-6.5kg for disc brake bike incl. pedals, size 52.
I talked to my Specialized dealer about the upcoming SL7. He had also seen the prototype as pictured above.
However, he said it won't be released exactly like that, e.g. the integrated cockpit of the higher-tier models is missing on this prototype.
He says that dropping weight for next-generation is not high on Spesh's priority list.
S-Works model will hit 6.8kg easily anyways with right componentry.
Goal is rather to stay around the ~7kg mark and focus on other areas like cockpit integration (to keep up with the Joneses) and compliance.
Integrated cockpit on SL7 with hidden cabling requires more volume from the stem, headtube.
This comes with a weight penalty (see weight of new Cannondale SuperSix Evo cockpit).
Also next-gen Dura Ace will be 12-speed, again with weight penalty.
He therefore expects the SL7 generation to be a tad heavier comp. to SL6, equal at best. Lighter? Highly unlikely.
Weightwise, the 6.8kg UCI limit seems to be appreciated by bike industry. Makes it possible to not only go weightweenie route and only sell the lightest bikes, but also go aero route and sell aero bikes. See how they suckered me into it?
Stiffness in roadbike frames for going fast is pretty much a solved problem. Not much to gain here anymore without compromising on compliance and weight.
I feel the manufacturer's goal is to stay around the 7kg mark and focus on topics like bling-bling (e.g. hidden cabling), disc brakes (sell new wheelsets) and new groupsets with heavier cassettes (but MOAR GEARS!).
Even more so... currently, the manufacturer's research & development efforts primarily go into developing e-bikes... but that's another topic.
