Quote from: ZenCarbonBike on October 26, 2026, 08:23:38 AMWhat are everyone's thoughts on these wider gravel rim profiles?

There is an increasing interest and demand for wide (outer width) gravel racing wheels where the inner width is kept narrow (sub 30mm).

Examples are: the reserve 48|53 GR wheels (IW:30mm/OW:44mm); Newman Streem G.62 (IW:27mm/OW:45mm) ; or the Roval Terra (IW:27mm/OW:38mm).
The motivation is that at the moment, only a handful of premium brands offer this, and there's still no competitively priced Chinese alternative on the market.

So ideally narrow down the inner width of these gravel rims to 30mm or lower.

I also got mine printed through jlcpcb. Since they also are load bearing I used PA12-HP Nylon (MJF). After a couple of years already in use, they didn't deform or degrade.
Concerning finish: you can let them sand for a smoother and get them dyed in a color of preference. You can also do it yourself with some fine sandpaper and a simple spray can.

So, another SL9 copy it will be  ::)

  • Which sizes would you want first?: Normally size 54/56, personally I don't care too much as long as the other (bigger) sizes follow not too long after.
  • What matters most to you in a frame?: 1) Geometry 2)aero features 3)(braket)stiffness 4)weight 5)price
  • What tire width do you usually run on the road?: 30mm WAM, nowadays being able to clear a 35mm (WAM) tire is a nice feature but not a must for a road tire. If I need to go wider, I will take a gravel bike
  • What would you most like to see in the next update: photos, weight, or test results?: photo's, geometry, specs

I've significantly cut down on my AliExpress purchases lately. Part of it is just having less time for cycling these days ;), but the economics have also changed.

For small items, it's rarely worthwhile to buy on the fly anymore once you factor in the extra €3 fee. For items above a certain threshold (around €20–€30 for me), paying that extra €3 can still end up being a good deal. That said, prices on AliExpress have become wild and unpredictable. To get a decent bargain now, you really have to wait for major sales like 11.11 or the Spring Festival.

On the flip side, I've noticed Amazon often has surprisingly good deals on the exact same Chinese products. For instance, I recently bought a brake bleed kit on Amazon that was virtually identical to the AliExpress listing and cost almost the same.

Ultimately, all this does is incentivize local European distributors to import Chinese goods in bulk and resell them locally. I really wonder if this is the "innovation" and "stronger EU market" lawmakers intended to build. The additional Shein/temo tax in france has that same intention, but big brands (i:e: the popular clothing stores) get their products from asia as well and are not targetted.

I'd love to buy locally made gear, but it's disappointing that we struggle to produce affordable, high-quality basics in Europe. Take a simple component like a bike cassette—why can't that be produced in the EU at a reasonable price? Whenever a small European initiative pops up, they immediately target the boutique/super-premium market, positioning their product as high-end to chase high margins (though I realize they aren't necessarily making huge profits given their scale). In Asia, the mindset revolves around high volume and lower

On the agent aspect, it's something I will explore in the near future since prices on TaoBao are way cheaper than Aliexpress. For instance;  I have my eye on the Sensah ECS groupset which is 350euro on Taobao and on TraceVelo's youtube video I say it displayed at 540pound on aliexpress. Those are situations where I wouldn't mind doing the extra effort to get it cheaper. Nowadays with the GPT's, its simple to get a guide on using those sales agents.

I'm also in doubt about this frameset.
At one hand: most of the time I would be in situations where 45mm is sufficient and with the right tire, it seems that a sporadical 50mm set-up still will fit.
On the other hand: 45mm as standard clearance doesn't justify a new bike for me. Going for bikes with big clearnance like XMCS and Tavelo, result in less responsive bike handling which I also not might like.
The Winspace G5 might be an alternative, but I guess the weight is not so low for those frames.

Are there any jackets/long sleeve jerseys with sleeve lengths that work for taller people? I'm around 195cm/90kg for reference. Long inseam winter bib recomendations would also be appreciated.

Spexcel works great: I received this one in size L (192cm,80kg) and it works great. With 10kg extra I would recommend one size up. https://de.aliexpress.com/item/1005012047015961.html
In general I'm pleased with their long sleeve jerseys and jackets as being a tall person with long arms/legs

@JR: thank you for this usefull information. It's contradicting the WW posts indeed. Would you have a chance to measure the height of both tires. It seems that that might be an important factor.

Something tells me it's no longer available because they broke and / or were soft AF. the design doesnt make sense, i'd want to see a bar closing the triangle.

The fact they didn't do a 36 but are still making 42 is baffling to me.

Can you explain yourself? It looks right now they are available in most of the sizes. I guess its a new design, and the statement is more: they were not yet available rather than they were no longer available.

Happy user of the iGS800.
I'm now using it two years and its a great substitute for my garmin 840.
Originally navigation was poor, but since they did a great software update one and a half year ago, it's perfect. The only difficulty I notice is the scale of the map is different compared to my garmin which makes it a bit more difficult to navigate offroad. Likely I can modify this setting to make them have the same scale, but I'm too lazy. 
Uploading and using routes with the app is also way faster than with Garmin.

Concerning functions, it has all what you need including the colorfull widgets and a climbPro feature (which might be called differently).
So far I have no issues with the hardware: the battery life is still superb (and long lasting) and the screen is still as good as new. Also the screen does not fade at the edges (which my previous garmins started to do after a couple of years).

Customer support: For the EU consumers: BikeInn.com also sells the computer at a competitive price, so if you want better customer service or warranty, this might be a good solution.

In short: a great substitute and cheaper alternative than the overprices big players like Garmin and Wahoo.
With the current rising alternatives from magene and others, there might be better solutions, but my gamble to purchase the iGS800 has zero regrets.

I don't think I remember a single crash in the super tuck. Much like a lot of the UCI's "safety" rules, it's not really about safety.

And my point about the super tuck is that they are so much further forward than you're getting with a progressive fit. The super tuck is safe, and that's 20cm further forward than my position. Your claim that a progressive fit is dangerous is wildly inaccurate. And that's proven by the super tuck which is even further forward. If you think a forward saddle is dangerous, that's a skill issue, not inherent with the position. The position in itself isn't any more dangerous or compromising than a rearward position. The position doesn't make one safer than the other, the rider does. If a rider makes the forward position unsafe, the same rider will be unsafe with a rearward position. What's unsafe is going beyond your personal skill level.

The thing with the progressive fit is that it's still pretty rearward. You're at most, equal with the BB. I'm still 5cm behind. You seem to think this fit puts you in front of the BB or somehow shifts your weight forward enough to make it unstable, neither of which are true. You're still behind the BB. It's more about opening your hip angle to allow higher power output and more comfort. Like any fit change it'll take some getting used to. But to say it's unsafe or dangerous is just wrong. You're fear mongering.
I don't agree with this at all.

First, the supertuck didn't cause crashes because riders only used it solo or in tiny breakaways when they felt safe doing so. No pro was ever supertucking down a steep, twitchy descent in a group.

Second, any fit or position that shifts too much weight over the front wheel is dangerous by default. Unloading the rear tire ruins rear-brake traction, making quick emergency stops in the peloton way harder. It also ruins control—MTB riders lean behind the saddle on technical descents for this exact reason.

Also, rider height matters here. A tall rider creates much more leverage than a small rider, so a progressive fit impacts their weight distribution far more.

To avoid the front-end weight distribution, the actual solution is extending the front-center length of the frame to maintain stability without forcing poor rider posture. This is a must for the modern frames who want to make this solution possible.

@patliean1: so what did you modify at the front? Did you increase your reach / stack, is the distance between saddle and handlebar now different compared to your past set-up? With past setup, I mean mainly your old bikes, rather than the VRT where you were searching from the beginning for a manageable fit.
It would be interesting to hear in more detail about those changes.

You can buy any bottom bracket. just knock the old bearings out and replace by a set of ntn, skf or other qualitative bearing brand.
