I had clicking issues on my current gravel bike and have fully resolved the issues. It can be a combination or an individual set of issues causing problems. I was able to narrow it down to 3 potential problems.

1. Regular thru-axles that require the hex wrench, might not be torqued down enough. I swapped to thru axles with handles. That alone helped stop disc rotor rubbing I had on my front fork when riding out of saddle

2. The freehub might not be properly seated. I would double check if there is any play with the hub to make sure it's not loose. I'm running XD freehubs and that was a problem I was having until I thoroughly checked and secured the freehubs.

3. Certain SRAM style pre-load cranksets might be problematic. I messaged the Mangoes Cycling Store who happen to be one of the main seller for the Riro carbon cranksets. They told me to use that crankset with 68-73mm bottom brackets only. That crankset only has a 105mm length spindle. I believe the EVOSID/Zeroing crankset only has a 109mm spindle length and while some sellers say it's fine for BB86 T47/86.5mm BB shells, it still might have issues.

Anyways, I have a Ceccotti RF25 gravel frame on order (same as the SPCycle G056) and now I'm wondering if I should have went with a threaded 68mm BSA frameset instead! I'm finding T47 just as confusing, if not more so than other formats.

This post was created about an issue on the SPCycle G056 and the Evosid Crankset, using the T47, and I was able to get it to work without issues after just straight up _cranking_ down the crankarm bolt, it just takes a lot of torque, tbh.

34cm hoods and 460mm drop flared bars. I like flared bars on my climbing setup for more control, but the narrow tops are nice when riding the flats. I haven't seen any other bar similar to this extreme range.

I have the 380/500 version of these on my gravel and I absolutely love them. Best bars.

Funny, I bought the same setup this morning. With coupon codes it was about $227 USD after tax. It was the cheapest option amongst the stand alone Magene PM and another PM/Zrace crankset with chainring. I don't plan to use the cranks though. I'm going to use the PM spider on my Riro carbon crankset instead.

Yeah, 227 after the coupons, I think.

Also not gonna use the crankset, but whatever/whatever.

Finally decided to pull the trigger on the P505 Powermeter. The cheapest option includes the Z-race cranks and a BB, lol... so that's what I went with, and had to get a new chainring to go with it, lol.

Road Bike Frames, Wheels & Components / Re: TanTan TT-X38 Build

Here's my final review of this frameset after about one year of using it. I spread my riding across four different bikes, so I've done only somewhere north of 5.000 km on it. Still, that's plenty of riding to give a qualified verdict:

The geometry & fit:

It took me a long time to get comfortable on this bike and start to love it. Probably the longest ever. Part of that is down to the geo, I believe. In my particular case the seat tube angle and saddle position (plus finding a saddle I'm comfy with for this bike. The seat tube is steep - i mean really steep. That in combination with the chunky seatpost makes for a harsh ride - with 30mm tires, however, it's actually not that bad. But I need setback because I'm a big dude at 190cm with long limbs. Particularly my legs are long. And if you need setback, be aware that you'll quickly run out of room on this bike. I got my saddle all the way back and the clamp is also all the way back. And the saddle is still further forward than I got it on my VB-R218/Chinarello.

The geometry is not actually as aggressive as the looks might suggest - I found the bars to be too high for my liking even with a slammed cockpit. I needed to use the biggest frame size to get the desired reach and also, because I like the look of a slammed stem more than a tower of spacers. I do also think it makes for a stiffer interface all around to have the stem sitting more or less on top of the upper bearing and the expander reaching into the head tube. BUT the -10 stem wasn't low enough. So I ended up getting the Tan Tan bars and now I'm finally at the point where the fit is where I want it to be.

Long term durability

This bike has given me ZERO issues. I had a few hickups during the build which are more or less expected on super budget frames like this, but surprisingly little happened since then - no creaks, seatpost never slipped, BB is fine. The Thru Axles started creaking after hours of riding in heavy rain, but that's normal. I cleaned and greased them and all good.

The disc brakes were hard to get rub free initially but it worked. The front disc squeals no matter which pads I use - it might be the rotor or I might yet have to get it faced by a professional bike shop. But it's not super bad. Only real issue: The headset bearings are junk and you should probably not even bother using them. Because of the opening on the upper headset bearing's top cap, water gets in there when you wash the bike. The lower headset bearing had rust on it. It's still smooth but I reckon it's only a matter of time. And in fact on my Velobuild frame the lower headset bearing needed to be replaced in less than 6 months after riding in the rain. I think most of the headset bearings supplied with these budget frames are junk and at least the lower ones which are sujected to a lot more dirt, grime and water, should probably be best avoided.

The riding experience


So first of all, tire clearance is more than enough. My tires measure 31mm (Vittoria Corsa 28c on 25mm internal rims). Everything up to (actual measured) 34mm should be fine. The drive side chainstay will be the limiting factor.

I'm lacking comparison with other disc road bikes since this is the first disc bike I built (other than my gravel rig), but I'd say this probably rides as expected for a pure aero bike. It's devastatingly fast in a straight line - in fact the fastest bike I own. I score lots of PBs on descents which I put down to the aero attributes but also down to the brakes. I do brake harder and later with this bike, because I have the confidence to do so.
Steering is neutral, which is good for high speeds in a straight line while being tucked. Weight distribution is more front biased, which when climbing out of the saddle leads to the rear wheel skipping quicker than I'm used to. The BB is VERY stiff, which is good.

What struck me most is that because of the neutral handling, the bike doesn't actually feel as fast as it is. If you'd ask me to estimate my speed on this bike compared to my VB-R218, I'd reckon the 218 to be quicker. And yet it isn't - even if it's pretty close. The wheelbase is longer, fork trail slightly bigger and so it feels more muted. Therefore, it actually feels less exciting to ride at times. But once you appreciate the speed and the (for me) very comfy position, it's very enjoyable.

Conclusion


Looks are obviously a personal thing but I really like the color and the horizontal top tube combined with a -17 stem. It kind of looks classic, while the frame attributes are decidedly modern and aero.

IMO, this is not an allround bike. I have done very long rides on this bike (+220km / +130miles) and it's alright. I use it for everything, including gran fondos but I also race on it so I want to feel at home on it even on very long rides. But I'd argue that if you ride purely for enjoyment and if your main focus are epic and long days out with your mates and if you like comfort across all kinds of roads, there's probably more versatile options out there.

The one area where it definitely feels less inspiring is on very steep climbs. It's just not as nimble when dancing on the pedals. It's somewhere between my 218, which for some reason just really shines in those situations and my gravel bike, which feels a lot more sluggish, probably also because of the squishy big tires giving way when standing.

But it absolutely shines on descents. I mean it picks up speed super quick and it rails around bends, it behaves super predictive and I kind of feel I'd need a bigger gear than 52/11. I just spin out way quicker than I used to.

Buy this if you want to go fast and hard, if you race and if you enjoy a pretty uncompromising bike.

The biggest CON about this frameset might be the weight (if you care about that sort of thing). The frame is somewhere between 1100-1200g. The bike as pictured is just a touch below 8kg, including bottle cages, Garmin and front light mount and pedals. I think, that's already as light as it gets. I'm running a fairly light carbon crank, a monobloc steel cassette, a Super Record Hollow Pin chain, pretty light Xpedo pedals (I think around 270g) and 36g Ridenow TPU tubes. You could probably run an even lighter saddle, lighter tires and rotors. The wheels weigh 1450g so there's lighter options there as well. But this is never going to be a weight weenie bike. So while this is a great descender, it'd probably not be my first choice if I was living in the mountains. For the mostly flat terrain that I (have to) ride most of the time, it's perfect however.

Value for money


My main objective with this was to build the most price conscious equivalent of a modern aero bike that I could get. That included used parts bought on the German equivalent of Craigslist, for example the cranks and chainrings, the saddle, the brake calipers (which I used mainly cuz I don't like the look of the LTWOOs) and even the tires. It's a 580 USD frameset (incl shipping), sub 500 wheels, sub 500 mini-groupset, 250 for the powermeter + cranks, cassette, chain, rotors and finishing kit. Well, and I invested in another handlebar. The bike cost me somewhere between 2.000 and 2.500, which I think is remarkable value for money. The resale value is zero, that's just the way it is with direct 2 consumer china parts.

But I'm not afraid to race this bike and I thoroughly enjoy it.

Fuck yeah, lovely review Seb!

I took a swing on the new winter/fleece YKYWBIKE stuff and... it doesn't quite match the quality I've expected from them. Well, maybe the quality is fine, but the sizing feels completely different.
 
https://www.aliexpress.us/item/3256806120127489.html - Long sleeve fleece lined jersey.
Ordered the same size I usually order in their jerseys and the jersey is *very* tight - likely should have sized up considering it's fleece lined, that's on me.

https://www.aliexpress.us/item/3256806036760169.html - fleece lined gilet
Holy shit, how is this from the same manufacturer? I ordered a size up compared to the jersey I mentioned above and this thing is atleast 2 sizes smaller. It's insane how differen the sizing is. highly recommend 2 size up if you're considering.

I think it's going to work.
Current setup on fork is ltwoo 160mm (using ltwoo hardware from the box).
the adaptor says 160 to 180mm.
Using longer screws, the adaptor goes between the fork and the existing setup as pictured above.
None of the holes in the adaptor are threaded, so it's really just a spacer, someone courageous enough might just put shims really...

So, the current setup is threaded into the fork at 70mm interval. I'll add the adaptor, using longer screws. And voila. In theory.
On the picture here, the 34mm spaced holes will not be used. I guess that's to screw on a shimano FM caliper, at which point i think you have a 160mm setup, not 180. Anyway, i dont run shimano.

That sounds simple, but it took me over a year to find that stuff at a reasonable price (12 usd + shipping). It should cost 4 bucks, but hey ho.

Hate to rain on ya here Serge, but the adapter i got form amazon is almost 1:1 the same as the lewis, but it doesn't work and the reason is really annoying.

The L-Twoo calipers have this bulge that goes down into the adapter they offer - that works in that gap in that adapter, but because "flat mount" standard is literally meant to be *flat* against the adapter or fork, you lose the lift/benefit of this adapter when you install it because the caliper isn't direclty mounted to the lifted part, it's mounted to the outside areas that don't give the full 20mm lift.

It's midnight here, but I'll try to sketch it out tomorrow to show you what I mean. Essentially, the little ridge that hosts the 34mm spacing is where the Shimano caliper would attach, giving it the life, but you're bypassing that with the l-twoo brakcet and going back down to a smaller lift, which doesn't *quite* do it. I was *almost* there, lol.

Same with the Magura posted here - almost *every* "flat mount" adapter tha'll get ya 20mm, the 20 mill is on the highest edge of the rise where the Shimano would direct mount, and as such, does us no good.

I did try to just use the adapter between the caliper adn the l-twoo braket, but because of the odd shape of the l-twoo caliper, the little buldge made it impossible.

This Magura adapter claims to do 180mm rotors:
https://www.amazon.com/dp/B0973NQN4N

That does look like ti'll do the job. I got the other one I posted today, I'll play with installing it tomorrow and see if it works!

Well I'm in Europe, so can't buy your links, first of all :) or import and what not, too much drama.
The first link makes no reference to 180. I'm a simple man, and I've already bought adaptors that didn't fit. So, I think the first one doesn't work.
The second one makes a reference to 180, but it's confusing.
So... My source is selling them for 12 dollars, I'm buying 7, and a friend is paying for the shipping because he wants his upgrade in winter... So I'll buy from my source, I think. But it doesn't mean there aren't alternatives. What I know is that I've been looking for months and never found anything that worked.

Of course, yeah. Curious what other options similarly you've tried so I can avoid them!

I ordered the first one because, it's 20mm, fuck it, lol. A lot easier to get 2 day shipping than have to email someone to order a single part, but as soon as that one doesn't work, I'll be going for the Lewis one, haha. Appreciate you sharing!

May have found another version more easily obtained here at Amazon: https://www.amazon.com/LQ-Industrial-Bicycle-Accessories-Hydraulic/dp/B0CNJZGDLY?source=ps-sl-shoppingads-lpcontext&smid=A23QJEODOLCAYG

or even: https://www.amazon.com/dp/B09SH8FV9M?content-id=amzn1.sym.8c2f9165-8e93-42a1-8313-73d3809141a2&s=sporting-goods&sp_csd=d2lkZ2V0TmFtZT1zcF9kZXRhaWw

Am I crazy or is these the same?

It's this i'm eyeing. https://www.lewisbike.com/lewis-fm-f-adapter.html
The issue is that i dont understand how it works. I've just emailed them to explain to me. So many holes, i dont see which ones have threads, not sure what threads where. I do know my fork is flat mount with 70mm between the holes in the fork, but beyond that...

I've been curious about this because there are a fuck ton of options out there like this - suppose that as long as they sit well as a +20mm spacer between the L-Twoo adapter and the frame, it's all gravy?

I think I found a 180mm adapter a la Peak Torque. I'm about to order a bunch.

Oi, do share! I had the adapter listed above with a set of 4-piston post mounts in my cart and canceled them because the spcycle store told me they only offer the 180mm flat-to-post adapter for rear.

14
Rhinowalk has a bunch of new-ish bags that all look quality. A year ago there wasn't a single top tube screw mount bag and now there are at least 4 models on ali that all look better than the cervelo bag I had to get, for cheap

I went and looked at the new series "Wilderness" and I'm really into it. Ordered the half frame and the top tube bag, really stoked to see the quality.

15
Thanks, that does look like this would work! adaptor for flat mount forks, 180mm, for post mount brakes! 4 piston & larger pads, you'd expect them to brake at least as well as road setups, and should legitimately brake better!
I'm already running 180mm at the back, the adaptor is widely available so i made the upgrade when i built my bike. works fine, i can vouch for it.

I think I'm going to go this route.

The adapter that you Jonathan shared seems to *only* be rear? I should be able to get a 180mm adapter and put it on front and a 160mm adapter and put it on back to accommodate those 4-piston post mount mtb calipers, yeah?
