DIY Gravel Bike Cyclocross budget custom 1x11 MTB Conversion from 26" to 29" SENSAH SRX PRO
Ғылым және технология
! Cutting parts away from an Aluminium frames can be dangerous!
But in my case i did some tests and measurements and for my weight it is absolutely fine.
I got this old MTB for free from my Brother ( ;* ).
And so the story began......
Some Alieexpress orders and a lot of hours later, this awesome bike was ther result.
This Gravel ride as good as the most gravel bikes but i spend much less (approx. 450€).
Parts i used from Aliexpress:
-29" Toseek carbon fork
-Toseek carbon compression top cap
-Rsik quick release
-Elita One carbon seat post
-SENSAH SRX PRO 1-11 Groupset
-ZOOM XTECH HB100 hybrid brakes
I hope you enjoyed this project.
You would really help reaching my dream by subscribing me.
Thanks

The geometry of gravelbikes is actually the came as it was on old Mountainbikes, GCN mentioned it is a vireo. Some brands even bring out "new bikes" that share the geometry with their old Mountainbikes.

Great build, nice to see someone using normal tools and budget parts. I watched another video where guy (Canadian but cannot remember his KZread channel name) mentioned starting a 26er to 29 conversion with a smaller frame than you normally use for a 26er meaning the top tube (pipe) isn't so high but I suppose it depends of geometry of the frame you choose. Enjoyed watching the build. Enjoy the bike.
Awesome build! I’m glad you’re enjoying the hard work on your rides with it.

I've build myself something similar out of a 26 inch hardtail. Although I chose 27,5 inchers as the hardtail wasn't my size to begin with. I stuck to the 3 by 9 groupset although I've got rid of a chainring. So now I'm riding a 2 by 9 Gravelbike with dropperbars and triggershifters. In addition I had to add an adapter for the rear disc brake. Originally went with cheap single piston, now rocking cheap dual piston mechanical brakes. Cheers

I recommend changing the carbon seatpost to aluminum. Your bike has a split seat tube at the back, so the carbon seatpost will wear quickly where the clamp is installed. For carbon poles, the cut on the seat tube is at the front.

It looks nice and am sure it performs ok too. Just be careful of your new centre of gravity. The bike is now higher than it was designed for and this means that you are riding "higher up" so you cannot quickly put your feet on the ground unless you hop off the saddle. To avoid this you can experiment with shorter forks that give the bike a more suitable BB drop of 5 cm or so. It makes a big difference when stopping at the lights and gives you more of a feel of sitting in the bike than sitting on it when riding.
Great video Man, similar to my idea what to do.

Nice, no nonsense build. Great to see as I am looking for something like that to build to ride the shoulder seasons when my MTB or fat bike stay in the garage. Where did you source the the wheels from? I would think those would bring the majority of the cost.
For people having concerns about modified rear triangle (chainstay bridge cut). While you don't want to do that in a super light thin wall road frame, he is reusing an old MTB frame for gravel use, and his MTB frame is extremely overbuild for that. You can see that the tubes are large size squares, not round, they are very thick walled. That frame is originally designed to do jumps on rocks. There is ZERO danger that anything will be compromised, the old MTB frame after the mods is still many times stronger than a brand new $1000 racing bike frame. It sure weights a ton (this one is probably around 2100+ grams without fork, when Specialized Diverge E5 alloy gravel is around 1200-1300 grams), but it will outlast any high end light weight frame
Looks great!

Ok, i liked the video overall, but cutting the frame reinforcement for the rear wheel area is a bad idea since ita an aluminum frame and it's supposed to be rigid and not flex. Another thing that cought my attention is cutting the bearing race, you are supposed to press it, by cutting it will not be as smooth rolling as it should be and it will absorb and distribute the forces from riding differently. Cutting the race normally wouldn't be much of an issue with a steel or alu steerer but the fork and steerer are carbon i believe, and i would never mess with carbon

But in my case with my weight i did some tests and measurments and its fine. But of course everything on my own risk! And yes normally i wouldnt cut the race too but in this case it was not possible because of the bad dimensional accuracy of the fork. So i had to cut the race. But normally if you install everyhing corryctly, this wont be a problem but of course i will check regularly (maybe every jear) if everything is like i installed it.

I'm an older rider starting back after a 10 year break. This bike exceeds my capabilities and has been easy to get comfortable riding. I'm mostly on easy trails with almost no street riding and have not been disappointed with the performance of the bike. My fitness level is far below what I previously rode with and because of that the mileage is going on the bike slowly. While I'm losing weight slowly, the bike seems to tolerate my 220 pounds just fine. The bike has been used by several family members ranging from 5'5" - 5'9".
11:40 - "pipe super high" tope tube being too high - I see that you have selected 29" size for Topseek fork, size 26" is what is needed. 29" size keeps MTB geometry, that's why the wheel opening is so big at the front and the top tube is seating so high.
