Re: Velobuild VB-R-218 Received my copy (Disc) on Monday and also ordered a set of RC-50 wheels. Complementing it with Rival AXS the assembly was straight forward, but some points one should take care of (if not already mentioned somewhere in this thread).

When you fit a DUB/30mm axle you have to file down a protruding rivet that holds the bottom battery cover. Otherwise, you can't mount the axle straight. Just remove the bottom cover and you can access the rivet. The BSA threads seem to be cut post-mold and co-axial alignment/facing is fine. I had to remove some residuary debris and paint, but then you can screw in the bottom-bracket by hand easily and crank-axle fits smooth. Break mounts seem not to be machined but are sufficiently flat/parallel - no rubbing. What you have to take care of is the thread-insert holding the rear axle. It is fixed with a small screw that may get loose/lost. It can then happen that the insert rotates, and the axle becomes loose. Coming from the factory without it (!) apply thread-lock to the screw and check regularly. Overall quality of the frame seems fine, but time will tell. Test-drive today did not reveal any issues. The frame feels firm and with 28mm/5bar sufficiently comfortable (for a race bike). The handlebar seemed quite flexible when putting power into the bike, but I have no experience with the original, so that might be normal.

Someone having long(er)-term experience?

Can someone tell me what spokes i need for this rim
https://www.aliexpress.us/item/3256805863224869.html?spm=a2g0o.store_pc_allItems_or_groupList.0.0.86b76a46E92BEx&pdp_npi=4%40dis%21EUR%21%E2%82%AC%2031%2C77%21%E2%82%AC%2030%2C06%21%21%21239.08%21226.25%21%402101eff117135512245803360eb854%2112000035490977194%21sh%21HR%21833424489%21&gatewayAdapt=glo2usa4itemAdapt


the rims are lb falcon pro 55 with ERD 530mm, i would like to use sapim cx sprint but what length?

I think you can try ask the aliexpress store actually! Ive done that in the past and they calculated for me and i double checked with an online spoke length calculator

Can you put some pictures from the non drive side, i want to see hidden thruaxle

how would you put that bike on the trainer?

thru axle is "only" hidden on the fork (drive side)

Re: Hygge Aero Carbon Frame Dear friends,

My frame arrived last week after a month of anxious waiting and complications. I built it and rode it this weekend—it’s fun, light, fast, and both stiff and compliant. I’m pleased with it! It weighs about 8 kg with bottle cages, Garmin mount, and Look pedals. Note that my Merlin CDR-2 carbon wheels are not the lightest at 1650 g per pair.

During assembly, I had some trouble routing the cables through the handlebars, but using a shifter cable as a guide made it easier. The other components were straightforward to install and adjust. The frame is pearl white, and its color truly shines in sunlight, with a sparkling effect and "laser" decals that change hues—definitely a head turner! I haven't had issues with the headset loosening, thanks to the new design C rings, and all bolts, including the seatpost one, remained secure.

I'm using a Shimano 105 mechanical groupset, a 3D-printed Ryet saddle (160 g), Supacaz sticky cush bar tape, and Continental GP5000 32 mm tires with RideNow TPU tubes. I installed a chain catcher for frame protection and put Zefal Skin Armor under the downtube and in other key areas. The brakes are Juin F1 hydro-mechs and they fitted by the skin o' my teeth at the rear mount (160 mm rotors). I still need to adjust my hood positions, as they seem angled downwards too much. This frame is size 52 M, and it fits me perfectly (180 cm, 73 kg). I left full stack of alu spacers under the handlebars and will decide if I'll slam it futher down.

Here are some photos I took during the ride but they don't do the justice - it's more beautiful in person! (Sorry for the dirty rims and anti-Velominati postioned tires and valve stems!). Hope Hygge won't steal my photos or will at least credit anyone who posts their photos after they put it on their FB or Insta.

P.S. I don't know if they've changed the handlebars but they have different graphics and 6 Nm torque written. Handlebars are pretty stiff.

Cheers!

Weights:
frame 56cm  910g (with both derailleur hangers and 5 bottle cage bolts)
fork 401g (uncut)
cockpit 402g (115x410, with guides and computer mount bolts)

Anyone here can measure tire clearance of the frame and fork?
I'm about to pulling the trigger but not sure if I can put 34-35mm actual width tires front and back.
I have schwalbe pro one 30mm on 26mm internal rims. They measure 33mm. Fork is super wide can probably take 40mm, same as seatstays. Chainstays are the narrowest point but there's still a bit of room. I think 35 should fit.

Re: Speeder Cycling SC-R55D Received my SC-R55D a few days ago. Almost 2 months from the order to receiving it at my door. Shipping was only a few days (Fedex International Priority).

Size 535 (more like a 56-58cm).

This is my first carbon bike, I'm not sure what's normal and what isn't.

NOTE I specifically requested it to be unpainted. So, naturally it looks rougher than one you might receive with the standard matte clear coat. Don't judge it too much based on the unfinished appearance. I'll disassemble and paint it in the spring.

BB Shell
I measured the BB with a bore gauge, 6 measurements per side and averaged.
DS: 40.97mm
NDS: 41.02mm
Could be better, could be (far) worse, I think the ideal is like 40.98mm-41.00mm.
DS should be fine, NDS I might use a bit of Loctite 641 for good measure, but will see how it feels first.

Frame + essential small parts (hanger, FD tab, seatpost clamp, rubber cover): 905.7g

I didn't purchase the offered thru-axles, getting some blue ones from elsewhere.

Notes/Issues
  • It was packed well
  • Carbon looks pretty good on the inside. I assume EPS molded. No large wrinkles
  • Brake mounts look good
  • Seatpost slides into the frame easily, certainly not too tight, perhaps could be a bit more snug if anything
  • Geometry of the frame seems accurate. The fork length however is ~4mm longer than stated (measures in at 374mm)
  • Headset bearing seats look good
  • Seems to be compatible with mechanical shifting? There's an exit hole behind the ST (in addition to the FD Di2 wire exit hole)
  • The seatpost wedge clamp is definitely better finished than the one shown in Peak Torque's Tavelo Arow review (sides are nicely rounded), but could probably still use a couple minutes of sanding to make the top edge smoother where it contacts the post.
  • :( The pocket that the clamp sits in is angled, so it falls right into the seat tube when removing the seatpost. And it's not easy to hold it in place with your finger either, again due to the angle on the bottom.
  • :( The rubber cover for the seatpost clamp touches the grub screw in the clamp which prevents it from sitting flat on the top tube. Also, it fits kinda loose, not sure if that's common, but I assume it will jump around a bit on rough roads, or even in the wind.
  • :( HT/headset/fork vertical gap is about 1mm on both the top and bottom, which is noticeable from the front and sides. Weatherproofing is poor. Not sure how much of the gap is due to the bearing inset vs. the non-FSA ACR top cover. Might be better with a real FSA cover?
  • Lower headset bearing sits kinda high on the bearing seat. But probably fine.
  • Cable routing -- there's a guide tube in the NDS chainstay going to the rear brake. And the fork of course. But I don't see anything for the rear derailleur. And it didn't come with a foam sheath to prevent rattling in the DT.
  • The DT water bottle could have been placed lower for aero I think. There's a few cm between the two.
  • :( The threads in the fork dropout are kinda rough, one of the first threads is clearly a bit damaged, and there seems to be some excess resin that made its way to the bottom of the threads. I tried threading in a 1.5 pitch thru-axle and it felt quite rough. Ordered a rethreading tap to chase the threads, let's see if that works.
  • The additional zero-setback seatpost I purchased has a 2-bolt clamp rather than the 1-bolt Ritchey-style clamp on the setback post. So anyone worried about the 1-bolt clamp slipping might consider the zero-setback seatpost, if your fit allows it.
  • Tire clearance -- fork can fit some larger tires for sure. Width between the fork legs is around 50mm, not sure about radial clearance. Wouldn't be surprised if it could fit a 38-40mm tire leaving 5mm around. On the frame, width between the chainstays is ~40mm, so personally I wouldn't use anything wider than 32mm actual.
  • Rear flat mount bosses are 20.8mm tall, for those looking to buy the correct length bolts.
  • Wish I had thought to order an extra seatpost clamp in case I lose it.

Aero
Random dimensions for unscientific aero weenie comparisons:
  • Seatpost is ~21.8 x 33.4mm. Wider than supersix (15mm)/sl8/etc
  • Fork legs are ~16.5 x 40mm in the middle. Slightly narrower than supersix
  • DT is 43 x 63mm in the middle. Narrower than supersix
  • HT is 45 x 73mm in the middle

As I might've mentioned earlier, I'm doing a weird setup with a +17 deg stem to approximate the simplon/cervelo/bianchi/colnago thing and to get enough stack for my tall self. Then I'll design a fairing that encloses the stem/spacers/cables to make it sleeker and more aero. Hoping to finish it up by mid-January and have it ready for spring racing.

Re: LEXON Road Carbon Crankset I finally managed to fix the chain line issue on my setup. My BB is 90.5mm (BBRight). As others have pointed out with chainring issues, the same problem exists with the spider. The machining quality is poor - some tabs on the spider are 3.4mm thick, while others are 3.6mm. The spacers included are also the cheapest imaginable, and their thickness is inconsistent (not 1.5mm but 1.4mm or 1.6mm instead). I think the chain line problem comes from the spider’s incorrect depth.

I’m using Ultegra 11-speed, and to resolve the chain line issue, I had to add 3mm spacers to the drive side. However, this left no room for preload adjustment, and tightening the crank bolt added extra stress on the bearings. Additionally, with the 3mm spacers, the crank arms were no longer centered relative to the rear wheel. I figured that if I used 1.5mm spacers on the non-drive side and adjusted the preload ring by ~1.5mm, I could center the crank arms. While this helped, the chain line worsened, as the spider was pushing the chain too far in, causing it to rub against the inner plate of the front derailleur.

Here I realized the spider itself was the issue. After searching online, I found a replacement spider from Stone with similar dimensions but slightly less depth. I decided to take a chance and ordered it, and thankfully, it worked. The new spider had a ~1.5mm shallower depth, reducing the need for 3mm spacers to just 1.5mm, and I could finally use the preload ring. The chainring tabs on the Stone spider were also properly machined, with a uniform thickness of 3.5mm, similar to Shimano’s. I slightly adjusted front derailleur and everything looks okay for now, however I haven’t been able to properly test it outside yet, as it’s winter here.

Initially, I wanted to return the crankset. The seller contacted me, begging not to return it through AliExpress, as he’d lose money and the crankset would just be recycled somewhere at AliExpress's warehouse. He promised to cover all costs if I shipped it directly back to China. I asked him if he can provide any solutions and decided to give him a chance, but after two weeks of vague promises and no real solutions, I found my own fix and asked him to compensate me for the replacement spider. At first, he claimed it was too expensive and suggested splitting the cost 50/50, but eventually, he agreed to cover the full amount. However, it’s been nearly two weeks since then, and I still haven’t received any refund. Now I'm being simply ignored.

So, I DO NOT RECOMMEND buying this crankset unless you’re confident you can handle the issues yourself. The crank arms and spindle look good, the rest is bad, and if anything breaks, don’t expect much in terms of support. While I’ll probably keep the crankset, I’m still unsure about its reliability since I haven't tested it outside.

Re: LEXON Road Carbon Crankset Following up on my previous post about the gap between the power meter and the crankarm, I reached out to Lexon, and they assured me that this gap is normal. Being a bit stubborn and skeptical about their response, I decided to take everything apart and remount it. After doing so, I can confirm that this gap is indeed “normal.”

In addition, after receiving a set of spacers I ordered from AliExpress, I went ahead and mounted the crankset on my bike. My bottom bracket is a Shimano BBR60. Before installing the Lexon crankset, I measured how many spacers I needed. If you check picture (1), you’ll see that I had 1.5 cm of spindle remaining with my Shimano R8100 Ultegra crank arms. After adding a 1mm spacer on the non-drive side, I achieved the same 1.5 cm clearance with the Lexon crankset.

From what I can tell, this crankset pairs well with the BBR60. It spins just as smoothly as my R8100 Ultegra crankset. I’ll be testing it out on Zwift during the holidays, and I’ll update you if anything comes up. So far, so good!
