Road Cycling

You're more insightful than the conversations I've had with chatgpt about this :cry:

I was also considering the Domane 5.2 and 5.9 from around 2016.

You can get these bikes for less than £1000 which seems fairly reasonable, obviously depending on condition.

Not sure about old di2 though...
Define 'old' di2?

If you mean the 'first' 10 speed one 7900 series then no, best to steer clear. Components are not cross compatible and generally really expensive. It's not as 'plug & play' as the versions since. Although that's from 2009-2011 so a bit early for the year models you're looking at. External batteries.

The next version is generally 10-11 speed, 6700-9000 series from 2012 and further evolved/trickled down into Ultegra in 2014 with 6800 series. External and internal batteries. Evolved again in 2016-17 with Disc brakes and 8000-9100 series. This is probably/maybe what you're seeing. I just fitted that later 6800 series the last couple of seasons to mine (mixed with some 8000 series). Pretty bombproof, uses the older bigger/thicker SD30 cables. E-tube and easy plug & play so able to mix some of that early stuff with newer 8000 series no issue. I love it! Fit & forget! Everything is wired together (no wireless). No problems going this route - you can still buy parts of it new and has a massive thriving second hand market. Some evolution to a new plug standard SD300 with thinner cables and GRX, 1x setups and more TT button options in 2019, but you can easily convert, mix & match the plug types and most of the components together. It just works.

The current version being 12 speed released in 2021-22, tricked down again so di2 is now on 105 level R7100 components. 8150-8170 Ultegra, 9250-9270 Dura-ace. Front half of the setup is wireless to the rear with shifters being 'self powered', the derailleurs being wired to the internal battery with SD300 cables. Think some of the 105 might not be wireless, but unsure? Limited backwards compatibility.

Who needs ChatGPT when you have me & my bookmarks with the research and interest over several years... Not to mention my opinions! ;)

Eh?! How can they be calculated any other way?

I think the idea of "a zone 2 ride" is something that doesn't correlate to power or heart rate directly as you would traditionally think. If you want to find out where you should be HR or power wise accurately you need to do it in a lab with the proper testing equipment.

You can do the lab testing and say "your zone 2 is between 220w and 250w" but you can't say "Your FTP is 330 therefore your zone 2 is between X and Y". Thats what its saying.

I think the point is power and HR are output measures whereas the Z2 he prescribes is based on the way in which your body is generating that energy. It’s targeting the systems that give us endurance fitness way in the most efficient way when you consider time and repeatability. Obviously it’s very hard to determine that outside of a lab but things like the talk test are a good approximation. The main point is Z2 shouldn’t feel easy, but nor should it feel unsustainable.

Yeah, that was my takeaway. A lot of people seem to think zone 2 should be a stroll in the park.
 
What heart rate monitor do you all wear?

I've been using a Wahoo Tickr the last 18 months or so and I'm pretty sure it's about to kick the bucket. I may just need another strap but it seems they're known to not be the most resilient.

Any others worth checking out? Or will any Ant+ do the same thing?
 
I've been using the Garmin HRM with no issue. Looks brand new still. Had it 12 months plus and I am a sweaty man.
 
@Nutty_Death messaged me with a link to this bike on ebay - reposting it here if anyone else wants to advise (only thing I would add - it's very tidy so likely low mileage, but does seem high price for the age). Di2 is 6870 and although the listing includes a picture of an external battery charger... I don't see one mounted on the frame. So unless it somehow has one tucked away somewhere I can't figure out, it has an internal battery with SD50 cables - probably in the seat tube??? If it is an external (can't see any wires out the frame) Edit:Found it, mounted below the BB. It wouldn't take much to fit an internal battery. So I would factor in the cost of a battery (£120-130) and charger (£150) into your thinking as you don't know how reliable the charge/life of the existing might be and wanted internal *(although no issue with running an external battery there by all accounts). Maybe a Wireless unit (£50-60) so you can keep an eye on it and get alerts on a head unit, also can then play with etube and stuff.


Looks like the RRP was £4500 but they sold at around £3000 when new - https://www.sigmasports.com/item/Trek/Domane-59-C-Ultegra-DI2-Road-Bicycle-2016/98NW

Also being a 60cm you're after big frames, so towards the top of sizing range will see more deals/more stocks around new, would we expect that to mean S/H value drops more so depreciation is higher when compared to more medium sizing, I don't know. Maybe.

Had a TiCKRv1 (Blue) for 6-7 years before it eventually died. Almost bombproof! Bought an amazon strap as the original almost rotted away!

Replaced with a TiCKRv2 (Black) failed around 18 months old (visible moisture ingress), was prepared to buy another and messaged Wahoo to ask advice on how to mitigate (the v1 had a rubber seal around the battery chamber, the v2 doesn't), a couple of emails in 2-3 hours and they'd sent me a new one which arrived next day. Amazing service & unexpected support, so even out of warranty and with a bit of a design flaw they stand by keeping their customers very happy!

Still consider if this v2 fails and I'll happily buy a new one - as I've got good loyalty from the v1 and the way they've handled things with this v2 so have no need to look elsewhere. Also consider 3-4 years of use (with 1 free replacement when needed) for a generally otherwise reliable £40 product is a 'known' spend. Like something consumable. £1 a month for HRM! :cry:

Before the first TiCKR I had a Garmin, think it came in a deal with a head unit (Edge 500?). I had 2 maybe 3 replacement straps in a couple of years with it but was never that happy with it's reliability (or lack of). TiCKRv1 was a cheap alternative and my first foray into Wahoo... Since then nearly everything I have has gradually moved over to their products (head unit, trainer, fans) and I really rate them all.

Wahoo sent me a replacement ticker as the metal button on one side of the strap came clean off after 18 months there support seems to be spot on.
 
Hopefully they bless me with a replacement. I've got a few of their bits now (Kickr, Headwind, Bolt v2 and Tickr) but nothing has every needed repairing.

I have a feeling my Kickr may be on it's way out as it's 2nd hand and making a lot of noise (but this could just be vibrations in the shed making it sound worse) but I know in a few years when I have a bit of spare money I'd like to get a Kickr Bike
 
@Junglist My kickr core i brought from wahoo as a refurb as they were dirt cheep and had the same warenty as if i brough a brand new one. A couple of months later it started making a noise and support just asked for a video off it Kickr noise they decided to send me a brand new one and not had an issue since.

I got mine from ebay so I'm not really expecting the same level of support haha.

To be fair it works fine, just loud and a little slow to react to ERG changes (I notice this the most in the 'rest' sections) but there is a high chance it's all user error as I haven't performed a spin-down in a few weeks

Unrelated... Anyone with some experience of the Assos range? I'm bit in the dark what I should be looking for. I'm after a comfort short, thick and wide pad. My general is Rapha Core with some Pro Team, so tend to prefer thicker, struggle with Castelli these days, some Sportful ok, but really have nothing else. Want to branch out a bit to find a different 'all day' short and have been told Assos is the way.

Ha! Mine came off - or I actually noticed it was off last night. But I'd re-used the strap when they sent me my replacement, so had the new strap from the replacement still new in the box. Result!

Ask the question - but at least word it that you're asking for help/parts/support and not flat out asking for a new one! Then see what they say/offer/suggest. Fairly sure for the TICKR they won't do 'repairs', refirbs or parts so you'll get a new one in a box. For mine they needed pictures of the front of it (without the strap on it for some reason), I'd taken pictures of the front, rear, all the model/serial and the box itself just not the front of the unit without the strap... Also proof of purchase!

Raise a separate ticket for the KICKR and ask their opinion of the noise. They'll need a video like the above - but definately mention you're not the original owner. I don't know if you'll get a cold shoulder, or just offer price on buying a new one. When you have the video post it up here and can advise, there's lots of repairs which can be done. Vibrations are probably bearing related - either in flywheel or freehub. Both can be serviced, possibly yourself (depending on ability and tools).
 
That is tempting. Waiting to see if we are getting cycle to work or not first.

I expect I'll probably get one in the new year before spring starts. hopefully
