 i hope i can use it on the parkway too

 @Outside- can you make all of the content free and stop being bums??

 Until you cross the bridge and drain it in one go.

 Its waterproof inside and out. Just fill it with water.

 If it’s waterproof just fill it with water and put a straw in it

 It's waterproof, so just fill it with water, sip it with a straw...

 @hellanorcal: ha

 The capri-bum

 @browner: hahahah

 It’s waterproof. Fill it with water and bring a straw.

 @hellanorcal: LOL i was thinking the same.. bit like a pool

 Just use the bottle attached to your bike. (Hater's gonna hate this one!)

 @bigtim: I know you don't have any mountains, but some people do and some people need more than one bottle of water.

 I don't know if anyone has mentioned it yet, but if it's waterproof you can just fill it with water and bring a straw.

 @BikesBoatsNJeeps: Or just fill it with water and use a straw...

 It's waterproof you can just fill it with water and bring a straw.

 Make sure the straw is waterproof too...

 I’d imagine you’re paying for the software to compare laps and segments. Pricey for software but that’s all I can think of

 Don't forget the subscription service too! 250 Euros is for just the hardware.

 greater accuracy? Lap comparisons? He does say its for racers laying down lap after lap and looking for consistency/small improvements.

 Garmin records 1 point per second This and SkyPro XGPS160 paired with Litpro record at 10 points per second which is leaps and bounds ahead in accuracy and allows for better ghosting, comparison, etc and thus more valuable from a racers perspective

 Sorry this one is 20 positions per S which is huge! That’s massive for accuracy and comparing lines

 @stormracing: OK, that makes sense, but only for a few of us. Mine will show;

1.00 Thinking about it
2.00 Pondering
3.00 Spot checking
4.00 Nervously smiling
5.00 Back to car for a brew

 @noplacelikeloam: for sure! Yeah, you definitely have to be seeking something a little extra for this to be the product for you. I use a garmin for regular rides but then Litpro when I’m on the DH track.

Hahah that’s a good system ya got going for ya

 @stormracing: but those 20 points per second each come with 1.5m accuracy, so up close the tracks are going to be fuzzy to say the least. With some averaging, it might be useful for a 5 second plus section where there are multiple clear line choices, if you're a real pro. Or just get Ben Cathro at the side doing ghost videos...

 I thought of the same, just a BS product

 My son who races World Cup DH uses one and loves it. it is very consistent and gives him a good idea of where he is on speed and time and definitely helps with his DH preparation. He makes suspension/bike changes then goes down a track he knows well and gets very good feedback. We have used all sorts of other methods from the simple handle bar timer to watches but this works the best for him.

 As mentioned, the 20hz rate is pretty key, but without DGPS you're limited to accuracy. If you were really interested in accurate lap timing you'd set a base station with a reference to a local geodetic marker, let it burn in for a few days and then reference to a body worn GPS, we've used this for tracking targets for human detection when I was working on some self driving technology back several years ago. We could regularly get accuracy down to about 2cm with a fairly moderate 100hz data rate. We built the system on bread boards with a small antenna in a Camelback since we were doing a lot of our work in the desert and the humans had to stay hydrated. You could probably build something now way smaller using Raspberry PIs and a low power transmitter. Our system was pretty compact, back then.

 @BikesBoatsNJeeps: A few days?? Nowadays cm precision can be achieved much quicker.

 @mountainsofsussex: here's a nice video of RTK GPS versus standard GPS accuracy: youtu.be/ZEQYJgNpwlQ

 Not sure I understand...even if it is recording at 20 times a second, it still is only 1.5m accurate - which is more than the width of a lot of trails and is a bike length difference, so despite being accurate in terms of recording a position, the position itself isn't that accurate for most of the sections that racers would be racing on. I like the idea though, just doesn't seem as accurate as I think it should be given the width of a lot of singletrack.

 @krpduner77: exactly. I think it’s a very valuable tool and use it the same way when out racing/practicing/testing. I think it works very well for what it is, the accuracy is pretty solid(no issues for me really) and definitely provides great info when practicing/testing
It’s the best set up I’ve found so far.
People on the internet can gripe all they want but there’s a reason some bigger names such as Amaury use Litpro and train with it. It works
Does your son use crossbox or litpro? I use Litpro with a SkyPro XGPS. Never knew about Crossbox but it looks solid.
I’m a big fan of Litpro

 @stormracing: He uses the Crossbox. Most of his buddies had the Lit pro (the red square box)and have also switched to the Crossbox. The Crossbox unit seems to be a bit more reliable in the trees and stuff according to them. He does really like it.

 @krpduner77: right on. Good to know. Appreciate the feedback on that. Might have to check out the crossbox now as it’s double the positions per S as the SkyPro(red box). Seems like a sweet set up!

 @stormracing: If you do I would recommend buying an extra charging cable as its proprietary and they are in Austria or something and if you lose or break it it can take a while to get another. My son is good at doing both Otherwise great product

 @mi-bike: I didn't want to start with "as an engineer", but I've spent some time with pretty expensive data acquisition, and I agree with you and @BikesBoatsNJeeps that differential GPS would be an enabler for pretty neat line to line comparison. It's a bit of a pro solution - most of the kit I was using was $100k+, so I've no idea if there are more consumer level tools that can do it

 @mi-bike: needs edit post button> meant to say differential with base station...

 @krpduner77: appreciate the tip! That’s a great thing to know that I’ll keep in mind.
Haha learned through experience. Thanks for passing on the good info

 I've never had a hydration hip pack, but I've had different hydration packs and been much more pleased with some than others in terms of comfort and bounce. I have a long torso and so really like Camelback's lumbar reservoir packs.

 I have Oakley clothing from 2010. Pretty sure Walmart products won’t last that long. Quality hopefully equals less waste and happy customers. I have a camelback hip pack that came with a sweet water bottle for like $40. Great quality and I trust it to go the miles.

 I have a Dakine Helipro (for skiing) that I have used for 16 years, my old Camelback was 10 years old when it got half inched from outside my apartment, my current Camelback is 5 years old and looks as good as new, my Dakine Drafter is 10 years old also and aside from a failed bladder still operates as new.

Quality products last so long, much better than Walmart 1 year life landfill products IMO and are often more specific to sport (Camelback has back protector, Dakine Helipro has probe, shovel and ski/board carrier) that make them incomparable to a generic cheaper model.

 Yeah, the price is very expensive for a lot of brand hydration packs. However, I would not say the quality or design is comparable to the cheap ones. I have used a lot of cheap hydration packs and several name brand ones. Most of the cheap will work for the purpose, but they did not hold up or the pack and bladder were designed really poorly. The name brand ones I have are going strong and been using them for several years.

 I don’t ride as much as I used to, but my Camelbak is more than 10 years old, goes in the wash every year, and there isn’t a stitch out of place.
My brother buys the WalMart stuff, and my brother always has a new WalMart thing to replace the one that broke. I paid $60 for my Lobo many years ago. I paid $80 for my kids Lobo a few years later, and both are in perfect shape.
I lost one of the buckles for the Lobo a few years ago. I emailed Camelback and they sent me the buckle for free. I like that. A lot.

 @Tonedelove: it's not that cut and dry. My longest lasting shirts are, no joke, $10 western shirts from Wal-Mart that I bought 15 years ago and wear ALL the time, including for trailwork sometimes. Just because something costs more doesn't mean it's more durable. Sometimes it does, but not always.

 Walmart and the like's aim is to build a good enough product for as cheap as possible. That means a product that won't be as durable-lower quality materials, less thought put into the design, more weight, corners cut (less bar tacks etc).

These things all add up to a value product. Walmart's bag will carry water, but it won't do it as well or as long as a performance minded product.

The best example I can think of is a t shirt-an athletic fit costs more because the cuts and seams respect the human body. The $5 dollar shirt at Wal Mart works, but its essentially slapped together to get the job done.

 I'd take $200 on a quality product that would last 10 years + (as my Camelback has) over buying a new Walmart backpack every two years as it wears out. Cheap is cheap for a reason (not that expensive is always expensive for a reason).

 @rickybobby18: yeah, I have boxers from high school too, but when talking about technical wear and packs it’s important for me to get items I can trust for the long haul. Readjusting straps every mile isn’t fun. Yanking stray threads isn’t fun. Fabric wearing through in high stress spots isn’t fun. Fasteners breaking on trail isn’t fun. And throwing away your bad decisions every year isn’t fun.

 @paulskibum: "it got half inched"

For the education of anybody else who didn't know what that meant:

half inch: vb. slang old-fashioned to steal. [sense 2: from rhyming slang for pinch to steal] (Freedictionary.com)

 @Ellocomotive: There are some walmart "athletic fit" workout t-shirts. I have a few for running. They are not bad. Some of the inexpensive stuff is decent, some not worth it.

 This question gets a lot more interesting when you have a business like Decathlon in the equasion. (There is a us alternative i am sure)
I think, it is dang in the middle between the two options debated here!
A bit less comfy and less feature packed than most "brand name" options, but still way above the quality and durability of the cheapo stuff, for a price just a nudge over the cheapo knockoff stuff.
In my opinion, ,the btwin 12l bag i have is a dang good compromise between price and performance.
I used an above mentioned dakine heli pro for years, that was a hand me down form my broter... solid 15 years of use in it i think... The decatlon one will not last this long, but not 1 season either. This is my 2. season on it and no sign of wear so far.
Th only thing i miss is the option to use it as a back protector, but i am planning on upgradeing it with a generic sas pad. We will see!

 @paulskibum: Haha, yes, I still have a Helipro I bought back in 2002.

 @jaytdubs: I mentioned upthread that I've ridden with a Camelback LR pack for years now, but my pack before that was a Dakine Helipro that I got for ski touring and used for mountain biking when I started to ride. I got it used in probably 2009, skied and rode with it, and then in the past years, kept it loaded with my smaller trail maintenance kit. I don't like the fit while riding quite as much, but that same stiffness makes it great for carrying heavier things and it is still in completely useable shape despite lugging a lot of dirt/sharp implements around. Great pack.

 Ha yes. Anyone who actually believes Strava is nuts. At best a guide but certainly not accurate and certainly not a comparison tool as used. Especially if from a phone.

 Strava via a phone or watch or whatever is OK over a longer distance but all the ridiculously short strava segments are asking for inaccuracies - at least thats what I tell myself when I am seeing my time is five times the fastest time on a given segment near me.

 @paulskibum: Strava is the worst. There is a hill near my house that has some fun, but short descents in the 1-1 1/2 minute range. Strava gives times from under a minute to up to 8 minutes on the same segment. I’m dumping Strava as soon as my subscription runs out.

 @endoguru: ha! If I put the ride on public I would have the KOM on a trail here by a looong stretch. And I didn't even ride it that day, that's some serious speed!

 sold

 The digital gauge on the Syncros looks exactly the same as the one in the Topeak Smartgauge.

 I think it matters less how accurate it is, but more how consistent it is.

 True! I upgraded my pump with a new gauge which reads up to 4bsr instead of 12bar and it's perfectly fine. Plus, it's not about the actual value but about hitting the value time and time again.

 My experience is that analog gauges are relatively accurate as long as they have the right range for the pressure they're reading. Eg: don't buy a 0-3000psig range if you want to measure 100psig, buy a 0-150psig range. Most pressure indicators have calibration screws on the back for setting zero and span as well, so not only are they accurate, they can be recalibrated every so often if they fall out. I've never seen cal screws on a digital gauge.

 1.5 meter on start point (1 second?) + 1.5 meter on end point (1 second?) plus what sample rate (1 Hz? would infer 1 second precision on both start and end points) gives as much as 4 second accuracy uncertainty. Much more than .05 seconds or claimed .01 average. And this is why Strava or any other GPS based timing may be fun but is directional at best.

 Seeing an interrobang in the wild is always a treat

 Thays why there is more than one hip pack being produced. I dont want a bottle holder on mine.

 I put my bottles on my bike and would prefer the hip pack use the space for something else. Full bottles are really heavy too and I prefer anything on my body to be as light and unnoticeable as possible.

 Double up and wear a backpack with a bladder at the same time.

 It is nice to have the display high for visibility but as you mention it is much more likely to break when it falls over onto that display. I had a pump with an analogue gauge in the same location as that digital one in this article and it failed after the pump fell over onto it too many times. After I got a replacement gauge I taped a chunk of foam onto the outside of the gauge so that it would not break again. It looked terrible but preserved the gauge.

 I just bought the dewalt cordless compressor. That thing is awesome. Not sure I’ll ever use a floor pump again.

 @Blackhat: i saw FIXIT or whatever that company is do a portable usb rechargeable mini compressor

 @Blackhat: fixmfg.com/product/eflator-digital-tire-pump

 @Blackhat: it is pricey though and uses an adapter for presta which is lame. Probably better options out there like the Dewalt

 @andraperrella27: That looks awesome. It’s significantly better than the dewalt if you just need to pump tires since it’s so much smaller and they both need presta adapters.

But mine is serving triple duty as a truck tire pump and camping mattress deflator. And you can use the battery to jump start a dead vehicle with a little foresight. Oh, and I just figured out how to use a truck tire as a tubeless inflator tank. And it can run on 12 volt if the battery is dead. And it’s easier to pack in the vehicle than a floor pump. Just a ton of flexibility and convenience as an adventure device.

 I’ll second the cordless HH air compressor route. Ive got 2 diff nock off cordless pumps and they were both under $50.00 they’ll both seat tubeless setups pretty quick w/ those little adapters from LBS and you can stash one in your vehicle
there da shizz for bikes yo

 @Crankhed: Link? That's pretty neat if the handheld compressor can seat tubeless.

 One of them is called an Air Hawk and was a gift it may have been a bit more but the other one came from Wallmart. idk if you have access to a Harbor Freight but i think they have em too @jojotherider1977:

 Bontrager Dual Charger is the best pump i've ever used as a road and MTB household.

 A stick of gum: $.05
A drop of pine sap: free
A drop of mint: free

Same

 I want to know how well calibrated it is

 Their punctuation was not great, to be fair.

 This guy's asking the real questions.

 Who's managing the couple-thousand-buck base stations for this RTK-equipped couple-hundred-bucks lap timer?

The 20 hz update rate is hopefully for the entire system, and 20hz of IMU data can potentially help with precision.

 @justinfoil: Free ntrip corrections provided by gov. basestations where I live

 @LaurensVR: that's... Pretty damn useful

 We have free NTrip corrections in Florida called the FPRN provided by the DOT it’s centimeter accuracy/RTK and available w/any internet connection @LaurensVR:

 Its the Ocotocon, there was a review on pb in march

 That isnt what he said - the analogue is impossible to set to (I agree my Park pump is rubbish, my Topeak is better but still vague), the digital agrees to his stand alone digital to within 1psi. Depends if you think the stand alone or the pump is right and whether 19 or 20 psi is actually that important to you.

 I could care less about how accurate it is, I care about it being consistent each time I use it.

 I think you do want it to be consistently accurate though. You just don’t care if it’s “calibrated”. Otherwise, it could be consistently inaccurate and still fit your criteria.

 About $100.00 different.
