These videos are not reviews, nor is it an endorsement of the product in question. Just the checking actual weight of the thing.
I just bought a set of each type myself for my new time trial bike and got the following weight.
Continental GP 5000 TT TR - 28mm = 248,7 gram
Continental GP 5000 TT TR - 28mm = 258,4 gram
Continental GP 5000 S TR - 28mm = 282.5 gram
Continental GP 5000 S TR - 28mm = 287.6 gram
Great, love these videos! Regarding the TT TR, that’s about 5.7% of error. Coming from the outdoor apparel industry, I’d say that’s close to acceptable. I’d expect everything within 5% from any item with a liquid state production step. (The rubber in this case) Keep up the great vids.
Love everything you do. May I suggest doing a video about the weight of air in the tyres. I have measured it to be quite a bit. Not surprisingly because it’s pressured.
What?!
@@SuperDodoe If you don’t understand, read again.
Unsolved RUclips-Quirk: when people delete their comments. You can weigh the tire without air and with air in it.
you can do that, but it is relative meaningless; the air inside a 28 mm tire pumped to 6 bar adds only about 1.5 g to the wheel, so you can neglect that, even as a weight wheeney
@@fiddleronthebike I don’t think that is correct. I weighed my wheels and it was a lot more. 1 Liter would be 13 grams unpressured. At 6 bar and 0,5 liters this would already be almost 40 grams. Or am I missing something?
GP 5000 28mm clincher is 242gramms measured. Michelin Power Cup clincher 237gramms. With 30gramms TPU these are the way to go for weight weenies. GP 5000 clincher is also much more bullet proof against punctures vs. STR/TT.
On paper that maybe, because of tubeless, the gap kind of closes. And in the real world 600miles in, ridding over very flinty and sand cover roads I have yet to see any cuts in the tyers.
but then I run these on on resvere 40|44's with 25mm ID and the 28s blow up to to around 32mm wide on these rims so I can run pressures into the high 50's depending on the roads and dryness of the route. I really love the power cups they are miles better than any of the GP's but until Michelin up date those with a larger tread cap on my wheels they're a no go, and on many modern rims over 20mm ID.
Not bad weights for 28mm. I've just received some IRC Pro Formula TLR S-Light in 25mm and they're 224g. My Challenge Criterium TL in 25mm are 230g.
What's the difference between STR and TTTR? is one strictly for tubeless and the other on can be used with tubes? Both are TR (tubeless ready?) so it's a bit confusing.
All can be used with tubes or run tubeless.
The TT TR (TT stands for time trial) is a lighter and had better claimed rolling resistance. But is less durable than STR.
For everyday riding the STR is probably the your best bet between the two (if you’re not counting grams)
@@slayerofgrams Thx!
damn. I just checked my bike and have the GP5000 S TR, didn't even realise there were two GP5000s
I use the GP5000 S TR in 32mm for gravel riding, I bet this wouldn't be a great idea with the TTs.
@@chrisko6439 that would probably be a waste on the gravel. I don’t do gravel though but I am on 32mm as well.
There is also the AS TR. So 3 variations in total.
GP5000 S TR - I found them not very reliable .... maybe mine bad luck? GP5000 (standard) worked for me for 2y. but with S TR (tubeless) i had problems in last 3 months, and i had to pump them up every day.
maybe they are too thin ???
Tubeless in general you will find yourself having to add pressure most days, it's akin to running latex tubes but no wear near as bad. But you should only lose around 1-2 PSI in a 12 hr period. If you're losing PSI at a rate of knots then there is something wrong with the installation, My Gp 5k s tr's held air for hours without sealant and are actually some of the best tubeless tyers for road I have come across in that regard if not the the best.
I use orange seal reg I think that the keys for Conti , from what I have read GP str are happy bead fellows with this combo and proved as much, beyond that make sure the rim tape is perfect and has been compressed for a few days with a tube in the tyre prior to the conversion. Something that really helped me was to use the Reserve Fillmore valves, these are brilliant and allow the tier to be inflated with nothing more than track pump. Make sure you add a healthy first dose of sealant, I added 50ml to my 28's, on my rims they're big boys! running close to 32mm, so im really pushing them and ive had zero issues. with weeping side walls or anything I was all set up in 10mins. got them to hold air with no lose in 15mins.
Coat the tyers in soapy suds and look for air leakage get the sealant over these problem areas, leave the wheels on side on top of a bucket for a few mins allowing the sealant to settle
all the time squeeze the tyres between your fingers enough to compress the bead ever so slightly and the sealant will find its way in to gaps of bead. Often the problem area.
Tubless you have to methodical everything has to be done just so, it can't be a "that'll do" mentality it just wont work otherwise and everything as to be supper clean
@@gaza4543 i run tubeless tires on MTB for almost 15y. I don't have problems with Pirelli P-Zero Road TLR, only with new Conti
Weighting my s tr at 290g :(
I don't know what's the margin error but if you're lucky it's lighter else heavier, you never know before purchasing :(
how many killometers can the tire be ok?
I bought 3 Conti GP5000S TR . They are all 285-290 grams. This is the tanwall version, could they weigh more than the all black or is this just a manufacturers variance ?
I don’t know but there was discussion on some forums that the tan/transparent version came in heavier then the black but could very well be manufacturers variance.
Tan is heavier.
Tan is heavier and has worse rolling resistance unfortunately.
Cont GP 5000 28mm tan wall = 239g and 251g. (quite a difference). - Clinchers. TR always appear to be heavier...
Clincher version or STR?
That TT version is one fast tire for the street without going full retard with thin sidewalls.
Seeing the weights I´m getting screwed... All my 28/30/32´s come overweight.
Still love them though..!!
lol might as well just stick with S TR
My 28mm TT's were 241 and 242 grams 🤣
