Boerklong Posted March 13, 2019 Posted March 13, 2019 I read somewhere that a mtb frame wont work as the bars would be too far forward. I have a Chinese Carbon ht frame that I wanted to use.
m-squared Posted March 13, 2019 Posted March 13, 2019 Thread hijack ... How does the Momsen STR 29 frame geo stand up to being a gravel build?
V18 Posted March 13, 2019 Posted March 13, 2019 Momsen str works well. Just buy a size or tow smaller. Same for the HT. Expect to have a moerse long seat tube.
Stretched@Birth Posted March 13, 2019 Posted March 13, 2019 I built this using bits and pieces I begged, borrowed and stole. It’s a 26er MTB frame (Giant XTC) with a rigid steel fork (was the most difficult part of the build to source), 29er wheels with 35c tyres, 9 speed and cable disks. Not sure what it cost in the end, but was not a lot...!

You need some shallow drop bars,short stem and maybe a riser bar.
Shebeen Posted March 14, 2019 Posted March 14, 2019 I’m keen on a gravel bike but given a shortage of cash I can’t buy new and nothing second hand that I can find would be in my budget. So the question, assuming a budget of around R7500 how would the knowledgeable folk approach building one from the ground up? Use a road bike as the basis? Or a hardtail MTB? Other things that should be considered?

johnson Posted March 14, 2019 Posted March 14, 2019 This is my attempt. It's a 26" mtb that I had so I didn't have the expense of getting a bike to start with. I Fitted a ridged carbon fork that was also the most challenging part to source. Got one from fellow hubber MTB TG. A friend of mine has a Trek Boon that he upgraded the wheels and had the original Bontrager's lying around. I Bought them for verry good price from him. The next challenge was the gear ratio's. 38-11 wasn't ideal. I Got hold of a Sram 44t ring. It's actually for a triple crank but with a small mod I made it work on the double crank. The small ring was changed from a 26t to a 28t. Using a 11-36 cassette the ratio is low enough to climb anything and high enough for a decent top speed. I've got 700-28 tyres on at the moment but test fitted a set of 35's and they work perfectly. In total I spent R7k.
Stevovo Posted March 14, 2019 Posted March 14, 2019 I am also building up a gravel bike. Took a carbon gt zaskar 26er frame, 10 speed 105 shimano shifters with 9 speed slx rd and shimano cable disc callipers Not finished yet. I have a road fork on a.t.m. i.e no front brake. Want to keep it 1x and try a 36 oval. Will go bigger in the future when I upgrade to a wider range cassette. Cassette is 11-36 a.t.m. with a 32 in front but thats too small. I had to put a 50mm stem with spacers under the stem to bring it closer and my saddle is as far back as possible to get back over the bb. Will need a setback seatpost. Still to come. I think the frame is designed for a 100mm suspension fork and when you put a rigid on it messes everything up. Bars drop and seatpost angle changes in the proses. Still not sure if I like it or not... Build cost me roughly 5500 but used bits lying around and got bars and shifters from a friend.
Farrnus Posted March 14, 2019 Posted March 14, 2019 we'd love to see some of our FARR OUT Cromo Frame-Kits used for some of these essential N+1 builds - so we have dropped prices a bit to help. all frame-kits now only R 5995 for a limited while - see them here

Koos Likkewaan Posted March 14, 2019 Posted March 14, 2019 https://www.bikehub.co.za/classifieds/352267-large-29er-gt-zaskar-with-carbon-rigid-fork/ If you sell those xt brakes, bars, stem etc youll have enough to buy the stuff for the conversion to drop bars Only challenge with this might be to find decent 2 x 10 Shimano Shifters at a good price. ( Tiagra won't work ) You will also need a 9 spd rear der. to work with the 10 spd cassette, but this is a cheap conversion.
Allrounder Posted March 14, 2019 Posted March 14, 2019 The pull ratio on Sram MTB and road mechs are the same. I have campy shifters and Sram derailer. works perfect. If you go that route, the shifters should put you back about 1800. 2x10.
Allrounder Posted March 14, 2019 Posted March 14, 2019 Currently I have 2.25 racing ralph tyres on it, so very comfy... It is a mtb frame, so I moved the seat forward and a very short stem.
