Drop bar gravel to flat bar hybrid.
I would like to convert my 105 gravel bike, Topstone, to a flat bar bike. I would need to change the shifters and brake levers but need to find the compatible parts. I believe the front and rear D's are good but am wondering what to do about the shifters as the bike is an 11-speed and currently has trim on the front D. Is there a chart that is easily understood for a relative novice to know what components are compatible? I have changed out BB and cranks so I have limited knowledge of bike parts but have never gotten into the hydraulic brakes other than bleeding the brakes. I understand that I should probably take the bike to a local shop but I would really like to do this myself. Any help would be greatly appreciated.

This bike is good guide...It has all the parts to do what you want including a trim on the shifter for the front derailleur.

Why the change? curious, not critical
note just changing bars and stem will not give a hybrid geometry full disclosure: i find flat bars hurt my wrists. I am a big fan of drop bars for versatility, efficiency and ergonomics |
You have better control of the bike on gravel with flat bars vs. drop bars. Especially the gravel that is loose like rolling on marbles.

I just did this to my son's Pure Cycles gravel bike. This thread is funny, because I also bought an Upan handlebar! Just a straight flat bar, however, narrowest thing I could find (620 mm).
Picked up the bar, a couple of SRAM MRX Comp Grip Shifters, and some Sora BL-R3000 Flat Bar Road Brake Levers that are compatible with his mechanical disk brakes. He got used to the Grip Shifters on Mom's old bike, so I stuck with those, rather than imposing trigger shifters (or thumb-shifters, my preference). I removed the drop bar and brifters, and installed the new cockpit ... but then got stumped at the cabling (and forgot to buy housing!). So I ended up taking it to the local LBS and letting them complete the setup. The only thing I have found is that the bars are a little wide, leaving the brake levers a little too far inland for where I find my hands in general. I may cut it down, but he says he can work with it. The advantages of youth, I suppose - he doesn't have decades of hand movements in his system yet. Edit: "Muscle memory" -- That's the term I was looking for the other day and couldn't remember it. I have decades of muscle memory that my son doesn't have yet. Confirms the getting old part, I guess |
https://cimg0.ibsrv.net/gimg/bikefor...24436aac2.jpegI did something like you're describing, and for the same reasons, to my 2000 Gunnar Crosshairs. Nitto North Trail bars, Brooks saddle, Shimano bar ends, Shimano brakes and levers. Much more comfortable for my neck/upper back.

Sweet Gunnar!
I've done this multiple times and start by getting the right bar on the bike then play with the stem, angles, etc. until it feels just right. There is very little chance that you'll get the setup right on the first attempt (I've yet to) and every time you ride it for a while you'll likely be considering and making adjustments. It helps if you have a number of spare stems and bars to try out. I also recommend using an adjustable stem initially to help figure out bar placement before shifting to a solid stem. |
Frank - just got a Topstone at a flea market this past weekend
low-end model - Shimano Sora 9 spd with mechanical disk brakes I believe it is a 2021 - dark (dark) gray metallic rode it a little yesterday - seemed good / I like - but obviously too early to determine how much I like but the first thing I did notice is the difference in braking - mechanical discs vs the hydraulic discs on my other disc bikes ... |
