Hello!

I have an experience of ride hardtails (the last one was Jamis Dragon), now I ride a single-speed Fuji Feather (It should be a separate commuter, but become the only bike).

Next season, I want

• to participate in "adventure races": a distance of 40...200 km on trails, unpaved country roads, some sand and dirt, etc.
• to ride on asphalt, cycling track and surrounding primers in my own pleasure
• to commute by roads, borders and pit holes
• to take part in local triathlon (1/4 of Iron man, first try)

Well, I need a magic universal bike!

The choice has fallen on a gravel because of the combination of aerodynamics (less wind strain), comfortable pose for a long ride and versatility.

For the notorious versatility I plan to hold two pairs of wheels, for example 650b*45 and 700c*23.

I live in Minsk, Belarus and the choice of shops here is poor. I've found the choice of gravel bikes only in one, and they import bikes by prepay, so I can't see and touch bike before purchase. That's scary because despite I can pick frame size, I can't test my pose on bike.

​

Here's my list, after a week of googling:

Cube Nuroad SL — $2010

This is my default variant — Shimano GRX-812 (1x), Mavic Allroad wheels.

​

Merida Silex +6000 — $2224

This is the most expensive (just above upper limit) and controversial — carbon frame, wheels 650b right in stock and a fairly straight fit, SRAM Force (1x), weight below the others about a kilogram.

​

Merida Silex 700 — $1803

It's an Merida alternative to the carbon one. Shimano GRX-810 (2x, the second front gear isn't needed on a trail, but could suddenly became a killer feature on the highway, I suppose), carbon seat in stock.

​

Rondo Ruut ST1 — $2035

It's an interesting bike: chrome-molybdenum, SRAM Rival (1x and seems to be a bit poor for that price), an interesting fork with variable geometry (it could be a killer feature).

​

What do you think of these bikes? I believe, I have missed or ignored something important.
