What i find the most problematic is how seraph made a 321g with uncut steerer copied fork while specialized one's are around 350-370g.
It doesn't seem safe at all for me...

Road Bike Frames, Wheels & Components / Re: SL8 Replica Build
« on: October 23, 2024, 04:11:11 AM »
So this thread started with a very satisfied customer and ended with an horror story.

Where is the truth with these frames, are there different sellers who sells different products or are all the sl8 replicas total garbage frames?

Design was ridiculous.  Wider tire clearance and rear 'suspension' to handle the gnar.  But ridiculously short front center and wb, and steep head angle in larger sizes.

I imagine it never made it off the drawing board.
On yishun website you have now picture of a real finished frame. For me micro suspension is more for softening the ride at speed, same as big tires.
But yes geometry is a bit odd, with huge stack, short reach, long chainstays which puts the bike on the relaxed side of gravel...

And i'm sceptical about the "suspension" with these beefy chainstays?

Hi.

I'm completely new here and willing to buy good chinese cross country bike. I settled my mind for dm936 based on all the threads here.  I prefer 2 chainrings but somehow it's impossible to get a new frame designed to have front derailleur.

So I contacted Carbonda on Alibaba and over their webpage..no reply.
How to get to them, has anyone any other contacts? Thnx in advance.
If you were talking about road or gravel, i'd say ok to double.
Nowadays in MTB, i don't see why people would want anything else than single?

If you want to contact carbonda use the website, someone will answer you, or find a direct email in this thread.

165mm cranks have been sold out or on back order for ages. Has everyone been moving to 165mm length cranks? Is there a fad or some recent sport science that came out showing clear benefit of 165? Or is it just the upcoming Tour de France and Olympics that teams are hoarding them? Just a few thoughts I've had.
This is the "pogacar effect". Everybody wants shorter cranks now.

In my case 165 for road bike feels more natural, is great for cadence, without thinking i gain between 5 and 10 rpm, a bit easier to accelerate and put immediate power.
For me it's another way to pedal and produce power with more cadence so less torque to apply.

On mtb i will probably stick to 170 because it's harder to just sit and pedal 90-100 rpm, but i'm probably sure i won't go back bigger crank arms.

Wendy did reply to me and tried to help we're she can. I really appreciate that. But she told me that there is only this hanger version. So I guess I have to go without the stabilizing screw and try to index it somehow. As I'm reading in other forum it is also like that to e.g. Basso frames.
It seems only recent shimano derailleurs have this "stabilizing screw". Don't worry front derailleurs work perfectly without this feature.

I made a quick comparative test with the 120mm rocker versus the original one.

I use a 42,5 shock and a 120mm fork. I just changed the rocker, same pressure in shock, SAG is nearly the same anyway, no adjustement on the bike settings.

The impressions you can expect by geometry changes are confirmed. You are more on the bike than in the bike, position for pedaling is in my case better, and bike feels more lively. Around the sag i feel it's a bit more supportive without losing comfort.
About driving what was predictable due to higher BB and steeper HA is confirmed, cornering is more lively, you lean and it turns faster.

If you ride mainly flat and prefer a XC feeling, i would recommend the 120mm rocker+120fork. 100mm fork+classic rocker gives probably equivalent sensation with more stability thanks the overall lower bike.

If your terrain is made of steep descents or fast corners (for example bike park)where you want stability i would go with 120fork+classic rocker.

I recently bought a roval sl8 handlebar copy on aliexpress. I get it for 100$ with all accessories included.

Quality is here, i just found the marks for hood position are not aligned but who really cares, screw for computer mount is to change if you want to have a good tightening without destroying it and interface between bar and mount is probably better made on the original too but it works.

About weight, it's light, mine is 325g for 400x100.
Rigidity is here on tops, i found hoods flex more than a alloy bar.

If you want to buy it, have in mind that exit hole is really small for 4 cables, i think like the original, it's made for electronic shifting.
Beware of the shape that is flat and wide on the top if you like this hand position.

I bought it on"hyyd sporting goods Store" which seems to have the lowest price with plenty of dimensions available.

29er / Re: XC Marathon Fully with... Drops? Advice?
« on: April 04, 2024, 08:33:20 AM »
I have briefly tested a fully mtb with a drop bar.
For me the drop bar doesn't allow to use the full potential of the bike and i always felt frustrated not to have a flat bar for more control. I lost the fun of the gravel and the ability of the MTB...
It wasn't a fun machine.

If i was to build a suspended gravel, i will go with max 50mm travel, big rolling tyres and road/gravel geometry.

Hello,
I bought a 120mm rocker to test it.

On static i can confirm that the bb is about 1cm higher and reach is 1cm longer. Thus the head angle is steeper, probably 67° versus 66° if use a 120mm fork on the 100mm chassis.
With a 42,5mm stroke shock, the 120mm rocker seems to have a bit more sag, in my case 13mm SAG versus 12mm, nothing really different and maybe in the margin error?

I don't have the 30mm bushing so comparative test done at the moment.

I bought all the replacement parts for 60$, that's a very good deal and they also send me some bearings ;) i had a UDH hanger so you can probably bought this frame a UDH rear triangle.

Road Bike Frames, Wheels & Components / Re: Elita One Saddle
« on: March 16, 2024, 07:14:18 AM »
It looks like a specialized saddle.
If the elita is really 100g for 50 dollars no wonder why it breaks easily ::)

The frame in the video is clearly not the frame in the brochure. Or are they doing like LC and the LCR017-D, with final product different than pictures on website.

What's the real RD301-D looks like? ::)

Thanks again.
Just to have an idea and compare different frames, around which value of reach/top tube I should stay in order to obtain neutral/comfortable position (not race or aggressive)?
I'm 174, my gravel is a gra02 size 54(medium), saddle height 72.5, 100mm stem and 2,5 cm of headset cover +spacer.
I think 390 reach on the medium 707 is too much for you, you will feel overstreched with more than 70-80 mm stem. With short stem on a dropbar i feel the steering becomes very direct and a bit twitchy.
For fast gravel roads, S sounds better for lower stack (more aero position) longer stem (more planted)  and more seatpost equal more flex and more confort.
But M can do the job too, it will behave more like MTB.

15
Is it right? I always ride mtb and never teste road/gravel bike, so is quite difficult to understand geometry table
Don't worry 8 to 10 cm saddle to bar drop is pretty common for a dropbar bike.
You can always add spacer if you're not supple enough to handle a road position but you can't cut a headtube^^

To me, in the case of the 707, for 170cm tall, M size is too long and too high front end.
S is the better option, XS can do the job too but at the price of an agressive position which i won't recommend to a newbie.
And it's be better not to get a combo handlebar as it's your first experience in dropbar bikes.
