Hello to all foristas! I come today to share my new Gravel project with Chinese frame.
Choice of the frame: I was between the meinier grl15 and the Spcycle g026. Both around 5000 with taxes and freight. Both weigh 1200g
Characteristics of meinier:
-Clearance 57mm
-435mm from Chainstay
-80mm bbdrop
Advantages of Spcycle
-Clearance 51mm
-425mm of chainstay
75mm bbdrop
Both with more than 620mm in size 54, without toeoverlap for 2.2 tires.
I chose SpCycle. When studying about it, I discovered that geometrically it is identical to the Mondraker Arid, with a front travel fork ready geometry. Aesthetics is similar too, but it is not an identical copy.
This frame is manufactured by mondice in models 326, with Mondraker geometry and 316, with a bizarre geometry (in mathematically incoherent, by the way) thanks to a 395mm fork. Mondice is the factory, Spcycle only resells, this is clear.
After being the topic and the geometries, I had an idea: the 316 is too aggressive, the 326 is quite conservative. Wouldn't it have a middle ground?
Before deciding how to customize the geometry of the frameset, I looked for some references: Crux 5, was the target I chose.
Crux characteristics: 78mm of bbdrop (it's a lot, but with tires between 38 and 56 the height of the central is good. I decided that this was the maximum I could do to "lower" the bike, "my" geometry will be ok from 38 to 51mm.
According to the proportion of ~33% of relationship between a2c and bbdrop, I came to the conclusion that changing the original fork for another 1cm smaller (from 42 to 41) would result in a more aggressive geometry possible respecting the 78mm of bbdrop.
Choice of fork:
They had some options of 41cm in the ali... I opted for the one with clearence for 2.4, 41cm, the largest possible rake to avoid toe overlap and reduce the trail so that, even with long between axles, the steering is very agile.
I bought the Fkg40 from Winowcycle (manufacturer/factory) for 950 with taxes and shipping.
The pieces are on the plane...
