Re: Best sub $400 carbon 29er wheels Most vendors will supply the option of HG/XD/Microspline freehubs. In your case, you just ask or select XD and you should be good. Somewhere between 25mm and 30mm of inner width rims should do the trick for the rims. You should also look for at least 28 spokes per wheels and if you're hard on them, then go for 32 spokes for some peace of mind. The low cost carbon wheels will all be using hubs like Bitex, Novatech, Powerway or other chinese brands. They aren't that bad but require more maintenance for sure. Again, for some peace of mind, I would pay a little more and get some DT 350 hubs. If you can go with brass nipples, you should do it. It's a little bit more weight but they won't corrode as fast as aluminum nipples. Sapim and DT anodized aluminum nipples resists a lot better but most chinese wheels comes with Pilar aluminum nipples and those corrode pretty fast. As for hub width, just check for BOOST 12x148 for rear and BOOST 15x110 for front.

I hope this help.

Re: Ican S3 XC Frame
I appreciate the explanation but I think the ratio is off because 165X38 shock is 100 mm on most bikes so taking the trunnion in consideration 140 trunnion should be about 105 ,  the 142.5 should be about 112 and the 145 should be about 120.  Maybe the stroke changes that slightly but unless you're compressing the shock to get in the frame then the numbers are still skewed.  Not to mention that if it doesn't have capability to full compress the shock and bottom out then what's the point?

I'm not quite sure if I fully understand what you mean... But there seem to be some errors in your thinking. Please correct me if I'm wrong:

You say that "165x38 shock is 100mm on most bikes", do you mean that a frame with a 165x38 shock usually provides 100mm of travel? Well it may be, that many bikes with these shock dimensions have 100mm of travel. But the amount of travel that the shock stroke translates to, depends on the leverage ratio of the frame. And that cannot be "off", it is what it is. Every bike is different. That just depends on how the linkage is designed. Like some bikes with a 210x55 shock have 140mm of travel, others have 160mm.

The Ican here for example has an average leverage ratio of 2,5. That means that for every 1mm of shock compression, the rear wheel moves upwards by 2,5mm - on average. It's probably a progressive frame, so the leverage ratio will reduce throughout the travel.

Now for this, the only important number is the stroke length of the shock, which is the second number, like "38". The first number - 165 - is the eye to eye, so the overall length of the shock. That should usually not be messed with, since any changes will drastically affect the geometry of the bike. Also, it doesn't matter if its trunnion or standard mount. The eye to eye is what counts. In this bike, you should only run 165mm, trunnion or standard.

What the guys are talking about, is keeping the eye to eye length the same, but changing the stroke length of the shock. So when the standard shock would be fully compressed, a longer stroke shock still has some more to go, resulting in more travel. The limit of this is reached when the seat stays hit the seat tube. What Ben did, is go to this point of maximum compression and measure the remaining eye to eye distance, which is 115mm. A 165mm shock would need to be compressed by 50 mm to get to this point. But you need some safety room to avoid breaking the frame at the first bottom out, also because the bottom out bumpers of the shock still give way a little when it's compressed hard. That's why Ben suggested a 45mm stroke shock may work.

The rest is math. Let's say the leverage ratio is 2,5 at the end of the stroke (it's probably a little lower), then an additional 2,5 mm of shock stroke will give you 6,25mm more travel. Take that twice and you have your 112mm with a 45mm stroke instead of the standard 100mm with a 40mm stroke.

Sorry, a lot to read, I know... I hope I didn't misunderstand you, just thought this might help. Took me a while to get behind this linkage stuff too.

Re: XC frame comparable to Specialized Epic Evo (110mm travel)? Haven't bought it to test but icanbikes s24 looks the fit.

Re: XC frame comparable to Specialized Epic Evo (110mm travel)? Consider Ican S3 - https://icancycling.com/products/xc-full-suspension-mtb-bike-frame-s3#

66° HA at 120mm fork, and can take a 165x45 shock to gear 112mm travel. Very up to date geo, identical to FM936 from Carbonda. Longer reach than Epic Evo. Little bit heavier. FM936 comes in a superlight frame option but the longest travel shock you'll fit is 165x42.5.

*disclaimer* I chose the Ican S3 as it ticked all the geo boxes for me. I've done nearly 200km on it now and I love it. It's definitely on the chubbier side and I am working on that, have changed the front to a carbon wheel and lightweight hub, will do the rear when I get a bit more cash together.

Re: XC frame comparable to Specialized Epic Evo (110mm travel)? Ican S3, FM936 and the FM909 are the only frames I'm aware of that are short travel with a slacker front end. All 3 have steeper seat tube angles than the Spec, but for me that's a plus.

Re: The Different Types of Carbon Fiber and Their Characteristics It will be nice if this thread could also explain the differences between various tensile strengths and tensile modulus, e.g., T700 T800 T1000.

Re: How to post a picture Is there someway to do something about the size of the pics that are getting uploaded at the moment and the way they appear on the screen.  Using a windows PC here and the thumbnails that get dropped into the post are too small to see any real detail. Clicking on the pic takes them to their full uploaded size which in many cases is 3 to 4 times the size of the sites viewing panel which obviously means you don't get to see the whole pic at once and the only other option s to click on the attachment which is then downloaded to my PC, not something I want to be doing on a regular basis.

Re: XC frame comparable to Specialized Epic Evo (110mm travel)? If you looking at size M, the Topcarbon TCSF046/Lexon Riot in M or L (reach brackets the Epic Evo M) is essentially identical in geometry (BB drop, head angle, seat angle, chainstays) using a -1.5 degree angle headset (68 to 66.5) like the Works Components Angle Headset and going 110/120 travel. You could even go with a -2.0 headset if you want to go a tad slacker.

Re: DT 240EXP hub clones Goldix, Venfort I received the hubs, they look very good! Even one bearing (only one, I don´t know why) is from NTN. The others are from NRW.

My model is GDR310 so, no EXP240 version. The weight was 319, so very good, close to DT 240 in terms of weight.

Do you know any official website for this Goldix brand?
These are some pictures:

The most particular thing, from my point of view, is the red parts. The last one is like a lock ring to keep the spring in the correct position. This is missing in the DT Swiss desing. I think that these red parts are adding a bit of weight, this 10 grams of difference:

Re: DT 240EXP hub clones Goldix, Venfort I just dismantle, some more pictures:



Red parts:


Spring retention ring:


Ratchet rings:


I will compare with my DT350 hub that I have already... just to see if they are compatible like everybody says.

it could be good, DT replacements are easy to find.
