Brand New cSixx Chainring Set – 55/40T – 4x110 BCD Asymmetric
Selling a brand new and original set of cSixx chainrings.
I originally bought these for a project that is no longer going ahead, so they are now surplus to requirements. Purchased by me in late 2025 directly from the cSixx website. They are completely unused and have never been mounted. Retail price is $260 plus shipping and taxes.
The set includes matching bolt covers for a Dura-Ace 9200 crank, but the chainrings are compatible with all 4x110 asymmetric cranks (e.g., Shimano Ultegra, 105, etc.). The original chainring bolts are also included, making this a complete set with all accessories.
Specifications:
Ratio: 55/40
Shape: Round (not oval)
Compatibility: 4x110 BCD Asymmetric
Price: 200€
Shipping from Germany to EU (other locations after clarification)

« on: January 22, 2026, 02:38:47 AM »
I own this frame as well and built it already last year. No real problems in the build-up of the frame.
I used the delivered headset bearings, compression ring, cover and so on. My question: Is it in theory possible to install a normal FSA ACR headset and then pair it with an FSA ACR compatible AeroCockpit or do I run into any kind of problems? This whole headset standards-thing is confuing me a bit...

I have a problem with the one-bolt saddle clamp. My rider weight is 75kg, but the saddle tilt slipped several times. Already torqued it up to 12NM and used carbon paste. I do not see it holding up doing a race situation even at higher torque numbers. As I know my exact saddle tilt, I am honestly thinking of glueing in the inner part of the clamp.
Besides that, no complaints. Frame and build quality seems very good. Brake mounts are faced properly, BB thread was also good.

Did not measure, but bought the version that does not say "3mm offset". So, should be the standard version.

Received my frame and quickly installed the BB to check what chainring fits.
I run a 50t passquest narrow-wide chainring on a shimano road crank (Ultegra/105 R8000/R7000). It barely fits! Nothing I encourage anyone to do as it is without any safety margin, but it works. So any other crank/chainring combination up to 50t should be fine. 48t for sure.

« on: August 08, 2025, 04:39:40 AM »I've ridden the crap out of my Spcycle SP-M05 that I purchased on 2021. Best inexpensive lightweight carbon hardtail frame I've ever purchased.
Thinking about your problem, it is with the fork. There is a high probability that Spcycle purchases the forks they are using from another supplier/manufacturer. If this is the case, they may not want to admit this, and or their supplier wont honor a warranty to them. I purchased a 26" X 150 fat tire carbon fork from Spcycle 3 years that has worked well without any issues.
I wonder too if you are in the USA. Perhaps, they are disenfranchised with the tariffs, and how much it will cost them to ship a new fork to you, and decided to say screw it and blow you off.
No, living in Europe.

Update on the whole situation:
Like written before I ordered a new fork and told them that I expect a compensation. They answered really unprofessional and told me that they will not cover anything. Not a single word of "sorry" or anything.
Now they have my money from the order, but the fork does not ship and they do not answer any mails anymore in which I ask them to at least cancel the order and refund the money. Nothing.... Luckily I paid with paypal and just opened a case for this.

« on: August 05, 2025, 06:40:08 AM »did the rivet nut crack the carbon and fell out?
I had a "similar" problem with the the rivet nuts inside the handlebar where the garmin mount is screwed into. Suddenly my garmin and the mount "disapeared" while riding some mild cobbles. Problem was that the nuts were just kind of glued into the handlebar instead of beeing crushed as intended.
No, no crack visible. The rivet nut was just "pulled out" during riding.

« on: August 05, 2025, 06:38:59 AM »Are you sure you installed the fork properly and torqued everything down properly? Gravel riding puts extra strain on equipment, so it's a good idea to make sure everything is secure. I don't see how the dropout just started randomly rattling. I'm fairly OCD making sure everything is bolted down firmly. Where I ride, normal gravel riding can be life-or-death if my bike isn't setup properly.
At least it's just the fork that's problematic. I'd just buy an aftermarket fork and not mess with the adjustable offset. The less $hit to fiddle with the better.
For the dropout there is not much you can do. There is one very tiny screw that secures the insert. However, this was more like a little play. Not nice, but also not threatening. The brake thing was obviously the bigger problem. I just can say I ALWAYS use a (Wera) Torque wrench and never tigthened to more than 5nm.

« on: July 22, 2025, 01:24:43 PM »good to know. I find it very hard to trust frame sellers that use aliexpress. I guess you didn't go through via aliexpress? I think you may have better protection there, because it's in aliexpress' interest to keep customers happy, to some extent, for repeat business. It's also often cheaper on aliexpress because of all the coupons games.
Either way, in recent times, it means tantan and spcycle have brought back cases of catastrophic failures that we used to be afraid of years ago when buying chinese frames. In both instances, forks, interestingly. What i find really interesting is that lots of forum users are still buying the tantan x68 despite all the shadiness and failures. Looks like because it looks like an SL8, short of shooting them in the head, they'll just buy the x68. At which point, it's not irrational for tantan to sell garbage, because people are buying it no matter what. Not unlike fast food, in a way. Maybe something similar is at play with spcycle.
No, I bought from their online Shop.

Some context first: I have dealed with several Asian suppliers before and have not had any problems so far. Some even exceeded my expectations and offered a really good customer service. Unfortunately, Sp-Cycle cannot be included to the list of trustful suppliers.
Short version of my story:
Bought the Gravel Frame G068 last year on July 29th, so roughly one year untill now. Building quality was ok. The brakemounts needed some facing, besides that, nothing serious. However, after a few weeks of normal riding I experienced a play in the fork. Turned out the "FlipChip" Insert in the dropout rattled loose and the play was getting so bad that it was unrideable. First they did not respond anything to my mails. After a "not so nice" mail they were willing to send me a new fork. This took roughly 2 months (!) untill I received my new fork.
Then, two weeks ago, during normal riding on a flat road my braking suddenly felt "strange". I had a look at the fork and realized that on of the bushing/sockets of the brake mount snapped out of the fork! I could wiggle the brake mount with my bare hands. I attached a picture for reference. I again contacted them without any response. After a serious mail, they replied that "I can do what I want, but they will not send a new fork". Full transparency: After that, I told them that I will publish my story, if they do not agree to fullfill warranty.
Normally I am the one that "defends" Asian suppliers when someone is concerned and talks about Carbon braking, serious defects and so on. But in this case I really feel that this is a serious defect that can lead to really serious injuries. If they would have even responded in a professional way, I would be willing to accept that, but the way they are dealig with customers is just plain unprofessional.
