Berk - Any updates on wheel development?
I was wondering the same thing... Its been 6 months since we got a peak at proto type wheels, any updates to progress would be great! :-)

Jure - just fitted a padded lupinA to one of my bikes, now after one in white. Can you supply one!

Thanks

Interesting article on some new Syncros wheels which are one piece carbon (similar to what Berk has shown before)

Does anyone use Berk saddles with a Carbonice seatpost? Or with a similar seatpost clamp design (see photo)?

My saddle rails cracked on a regular ride and I weigh 52kg. Starting to wonder if the two may be incompatible with each other.

I use a very similar seatpost, with the same clamping mechanism and a Berk Lupina with no issues, in your case, not sure it helps if you have that type of clamp and what looks like a huge saddle bag (300grams plus) hanging off the rails too.

I use my Lupina with a MCFK seatpost that has a similar clamping mechanism. No issues yet, and I've used it extensively for over 18 months now. I'm 68 kg for reference.

All this cracks are covered by the warranty ?

I think you should contact Berk instead of posting on a forum
Will do, but, berk saddles are very popular here on WW. I was wondering if I was the only with such 'issue'. We are here to share experiences, so, for me, nothing wrong with my post :wink:
Have to say, brilliant customer service by Jure :thumbup: Warrantied without questions asked. A new one is on my way, the current one will be send back for investigation
Can you post again the photos ?

The saddle bag is about 200g. It's not actually that big, I only carry sealant and a mini tool in it, so I'd be really surprised if that's the reason for cracking. Yes in my case it's under warranty.

The Lupina is really the most comfortable saddle I've rode on. I'm going to try the same with the oval rails version and see how it goes. I haven't had any issues with other carbon saddles on this clamping system, although all the ones I've used did indeed have oval rails.

The yokes appears not to be parallel. On another seat post it caused them to break... here guess the unbalanced forces were higher than the rails could handle.

Yeah, I have the exact same setup with no problem (i weigh 68 kg, fwiw). My guess (as well) is that the bolts to the yolks not being parallel increased the forces enough to crack it, but I'm no engineer, so... Sorry man, that sucks

I have a carbonice seatpost and use with a lupina with 7mm rails but parts of passion yokes. Nil issues. I assume the bolt alignement moved when the rail cracked.
