New german brand "Bold Cycles" puts the shock *inside* the frame

Because it is not hard enough to get to the adjusters already .... hahahaha Smiling

Would be awesome for cooling, as if DT shocks aren't troublesome enough.

let me just check if the seals are weeping... Oh....

Well I like their thinking! Good to have some genuine innovation for once rather than just another wider headset, bigger wheel, extra sprocket.

By the way it's Swiss not German, and being protected from all the dust & cr@p a shock usually gets thrown at it, an annual service may be the only attention it needs.

Interesting business model too - order direct from the manufacturer and delivered right to your door.

I'll certainly be watching with interest...

Wonder if it's a push or pull shock?

A few companies are selling direct to the customer now, I wouldn't want to have to send a weird shock back to Switzerland for a service though.

It's a DT Swiss shock, and they have a service agent in Australia - you don't have to send your Fox shock back to the U.S. do you?

That is if the local DT distributor(Sheppard) has the gear to do it, getting the rubbish Scott DT shocks fixed is enough of a pain and they stuffed up a lot. Their fork was based on the old Pace fork for a long time which was also garbage(I owned one), I stick to the normal brands for suspension nowadays.

Fair enough Fairy1.

I've no experience with DT Swiss parts except their spokes!

I've had enough problems with Fox - three out of four bits of Fox suspension I've owned had to be returned for warranty repair, but thankfully the LBS and Oz service agent made it a relatively painless process.

My LEV also had to have a new cartridge under warranty a week before I was due to go to Rotorua, but the Oz service agent pulled out all the stops and got it back to me in time.

So, I agree that reliability, ease of servicing, and a good local agent is important, and if DT Swiss don't cut it in this department then I'd have second thoughts about a bike that comes with one.

"being protected from all the dust & cr@p a shock usually gets thrown at it, an annual service may be the only attention it needs"

I'm reminded of the old neoprene shock boots that were popular in the 90s/early 2000s

designed toprotect the shock from dust and mud, what they did was trap and hide the dust and mud so a dirty/weeping shock didn't get the attention it needed before it was too late

And I'm reminded of chain drives in factory machinery, and internal gears in vehicles, which last hundreds/thousands of times longer than the equivalent on our bikes, because they are protected from the elements whereas our bike machinery is constantly exposed to grit, water, and mud.

Or just ask anyone who's worked in a mine or offshore which bit of equipment lasts longer and needs less servicing - one exposed to the elements or one covered?

As I said, I'll be watching these guys with interest, as I think they've got an interesting idea there. Only time will tell if they're onto something, or the naysayers were right.

Yep things that are protected last longer but how protected is it though? I can't see that system staying 100% sealed and the stuff that gets in is going to go unnoticed, and thus not cleaned.

At the moment after a ride I wipe the dust off the shocks. Pop the seals every 20hrs or so and wet the dust seals, give the stanchions a spray with silicon spray before a wet ride.. How easy is that going to be with the system is the question.

+ the reason our chains and gears wear out so fast has less to do with dirt and grit and elements and more to do with the basic design of the derailleur system, ie using brute sideways force to derail the chain from one gear on to the next (yes ramps and pins and teeth profiles help but it's the side force that causes the shift, side force is the arch enemy of chain driven systems.)

Single speed gears last much longer despite being the only gear to share the strain and coping with the same dirt and grit and elements.

Put the shock back out where it was and give me a light weight, efficient, center mounted gear box and I will applaud your innovation.

Hats off to your experience Flynny!

However, my understanding of why our bicycle drivetrains wear so quickly differs a bit from yours, as I've not heard it being about shifting force before. I understood it's a combination of factors around the overall design of modern derailleur systems and the conditions of use they are exposed to. To cram so many gears in modern systems the chains, sprockets & chainwheels have become narrower, concentrating same force on a smaller surface area. Then, in order to give the chain more lateral flexibility to span multiple gears, bicycle chain manufacturers went from sleeved bushings (which are still used on motorcycle chains, industrial chain drives, and some single speed bicycle chains) to the swaged bushingless design in the 1980s. This makes the surface area of the bushings in contact with the pins even less, and allows dirt to penetrate more easily into the bushing. Then you regularly douse the whole lot in dust, water & grit and you get a lovely grinding paste which works its way into the bushing and creates the wear we're all familiar with as chain stretch.

Anyway, at least it seems there is one thing we can agree on - that things that are protected last better.

Which means what it comes down to with that new shock design is A. whether enclosing it does indeed protect it better, or is dust and grit still going to get in there, and B. ease of access to inspect & maintain, which becomes even more important if the answer to A is no!

Unfortunately I don't think anyone can answer that based on just the pictures released so far, which is why my attitude is to applaud the innovation, but a wait & see as to whether I'd want to spend my hard earned cash on one.

And agree, gearboxes and maybe belt/shaft drives are where it starts to get really interesting...
