Hi Fanie. Given its design with a shox and significant travel (>20mm) as opposed to e.g. BMC Teamelite with its MTT, Ill still categorise ours it as a dual sus, even though it has a flex plate. That said, were not aware of a formal definition of soft-tail vs dual-sus in the Oxford dictionary, so you can call it as you wish.

Morning, then are 14mm OD and 8mm ID.

We need an equation for the variable shortlist.

Hi Zorro. We have had clients use mtb as well as gravel wheels (rims) on various of our gravel projects. The 29er and 700c have the same BSD (bead seat diameter; 622mm) so you can use them for the same tires, given the inner rim with is appropriate for the tire with you plan to run. Also, take note of previous comments relating to expected tire pressure as there is a large difference between what most mtb rims can take versus most road rims with gravel sitting in-between. For 1.6kg you should be able to find a very nice set of Alum mtb tires that will work perfectly for a gravel grinder. Kind regards Team CB

Hi, sounds like Shimano E-thru type. Pics would help and you will need to measure the total axle length, and possibly the thread length. No easy task hus might also be worth the while to reach out to the manufacturer for the info. Good luck.

Wow, she came out nice, what a beauty! It was a pleasure working with you on the design and well done with the build Brad, your choice of components really complement that frame. Enjoy many many miles of smiles on her. CB

The silly frame that cant take 28c tires. Throw it in the Thames when your there again.

Nothing like a fresh winter morning race to get the lungs burning! Enjoy the Trailseeker.

Brave souls indeed! Hope the snow is kind to them.

..mmm, might or might not be one of the previous winners of the MUNGA.

Hi, handlebar type related to the reach of the bike. We went through a lot of trouble to get the frame handling right with different handlebar and stem combinations. Whilst keeping rider position a priority. If you don't get this right, you end up riding a hardtail with drops that equals terrible handling, and position which is no good for something like the MUNGA. Noting to do with the hardware of the frame, just* the geometry.

Don't quite agree with "carbon will be more forgiving for certain". Comparing Alum frame with CF frame "forgivingness" (compliance) based only on the type of material used is not very informed. You are firstly comparing an isotropic material to a composite, and also ignoring geometry, tube profiles and layups of the CF which has a much larger impact on ride characteristics of the frame than the material used. Point is: ride different frames (if possible) test different tires and wheels and decide on the feel of the total setup. Cheers CB

Smart man, a custom is the way to go!

Looking forward to the next couple of days, and enjoying the view on the roads! See you at registration.

Looking forward to the race. Sure to be a lekker one. See you guys there!

This is a fun question for a forum. That said: consider who where the response comes from just as much as what is said. Take the following from someone that ponders "perfect bike" quite often due to the work we do. I think there is no such thing as a perfect bike, but there is a perfect bike for you. You need to consider your build, riding style, position on the bike, handling you prefer, components that fit your riding/maintenance preferences. Take all of this into account then look at suspension compression ratios, wheelbase, tire clearance, front wheel trail, stem length, handlebar with ect to identify the a good bike for you. And then see if you fall in love with it when you see it, then youll know its perfect. Just two-cents from someone else's that loves riding (and perfect bikes). Enjoy the journey!

Would this one do?

Wonderful, thanks all for the help!!

If you Google photographers all you get is maternity and wedding stuff, not quite the same as sweet titanium.

Hi All. We're looking for someone in Pta to give a hand with a product shoot of a sweet dual-sus. Any recommendations? Thanks!

Hi, Ti welding is mostly done with TIG, and although a lot of guys can do beautiful TIG, the so-called thin wall welding of titanium makes it a different beast. I would be cautious doing a repair on the position of the crack as its one of the areas on the frame where there's is the highest stress/strain and a welded repair could make future failure unpredictable. Your welcome to drop a pm to discuss further. Thanks, CB

That's a pity, n-1 or moving to something different?

Never too early to get ready for this spectacular event, for riders and dot-watchers.

(Almost) all prep done. Who is in the run for top 10 finish?

This sounds like a lekker build indeed!!
