I'll have you know, my decision to buy a set of Carbon Jones bars was based on months of research, much soul searching, hours of working out comparative weight to cost ratios and 1 minute on the trail with them. I made a wise choice I'm absolutely sure :mrgreen: OK they were second hand on here and a fool and his money are soon parted.

I bought mine to try and solve the loss of sensation in my hands when riding, which they sort have helped. Have you seen the current price of them new, £399 :o At that price some sort of surgical option would have been cheaper :lol: That's over £100 increase in 3 years.

It's like all Jones stuff, over priced, but if you wish to join that exclusive club, then the price is irrelevant :grin:

Out of how many pairs though? Obviously it's not good but one failure doesn't make a poor product ... they've undergone the same test procedures as other bars.

Only to city and trekking bike standards , not MTB. There seems to some question over there suitability, but where bikepacking falls into the grey area between " trkking" and " mtb" is anybody's guess.

True. I suppose it's a blurred line and it's up to each of us to decide if or when we cross it.

Anyone for a 100% recycled plastic city runaround...?

My first though was if it would survive some off road bike packing. Would be a perfect bike to use between the park and ride, and work...

I wonder if it floats? No need to strap it to the packraft, just tow it behind :wink:

And imagine the storage options within the frame for bikepacking :o
We go out into the hills to lose ourselves, not to get lost. You are only lost if you need to be somewhere else and if you really need to be somewhere else then you're probably in the wrong place to begin with.

There have been multiple failures.

Not all bars run through the same tests. These (Paschier resin/bamboo bars) were tested according to the ISO test for city and kids bikes. Not the mtb test. There's a huge difference between the two.

All the gummi explanations on their website only showed up once users with broken bars went public.

How much is weight per weight is actually bamboo? Of one bamboo bar making brand I know that they use carbon sleeves and resin. Seems these are not much different.
As with a bamboo frame, just go check how much resin actually is needed. But yeah, so much greener than my 5 y old carbon bars, which are still going strong :wink:

Not so long story short; I would recommend then to folks I dislike.

My understanding is that also includes 'trekking' Gian but in fairness I, like everyone else isn't quite sure where that starts and stops. I shall continue to use them and report back on my progress ... unless of course I'm dead somewhere. :wink:

Perhaps not quite as much resin required to laminate as people imagine ... after all, a thin 'glue line' on well prepared surfaces is generally stronger than a thick one.

I just hope they have it sorted and don't run into trouble.
Their marketing goes beyond touring use after all.
And then there's also the issue with cold temperatures.
I find it quite sketchy. Seems safer to ride a penny on easy single tracks...

Edit: just went through their IG feed and saw a set of images how they're made. Seems to involve a fair amount of resin (eg. seemingly more than with prepeg carbon laminates).

There are two different, relevant tests here. One for City/Trekking and one for MTB. There are others for 'kids' and 'racing'. The fatigue tests for Trekking and MTB are similar. The test method is the same, applying a force to each end of the bar 50mm from the end. The cycle count is the same for both tests (100,000 cycles) but the applied force is different. In a test where the force is applied to both ends in the same direction then the force applied is 250N for trekking and 450N for MTB, so quite a difference. There's also a test with a smaller applied force where the application of force to each end of the bar is out of phase. These tests assume the bar is clamped in a stem. These are CEN tests from a while back. There are newer tests in play now, maybe @jameso is more familiar with the newer ones but I'd be surprised if they are much different.

Just had a look on the Passchier bar website. imho they're not very clear about the relevance of the testing they do and leave it as a grey area. They say they're not for DH use but are ok for 'trail'. So are they MTB bars or not? In all the info they give about testing they don't clarify that they test to EN City + Trekking, not MTB. They leave you to figure what level they're tested to (or even that there are levels) from reading a section of EN4120. As Steven pointed out the MTB test uses 45kgs not 25kgs of the C+T test which is a big difference.
So many 31.8mm clamp 'city' bike bars I know of from decent OEM manufacturers pass the MTB standard. Because the end use isn't clear and you can fit MTB controls it makes sense to test to the higher standard to be on the safe side, and it's not a difficult test to pass with a 31.8mm Alu bar of average rather than 800mm widths.

$15 each could soon get very expensive. I'm sure an M5 x 15 cap-head would be much cheaper. Oh yes, 200 in stainless for £19 or if you're reet posh £3.40 each for Ti including coloured variations. :-bd

Yep, rubber caps available too...plus the zitbitz have all got really sh1te graphics on them. These look nicer and a bit cheaper if you want bling, and easier to remove: https://www.planetx.co.uk/i/q/FSNITSSB/ ... SNITSSB-M5
