Quick question about bars, I’ve never built a gravel bike before…When I’m looking for brake levers for drop bars are there different sizes or are they all the same diameter clamp to fit the bull horn part?

I've never thought twice about lever clamp ID vs. drop-bar drop diam OD when considering lever and bar combos and I've mish-mashed a wide variety of vintage/new-ish/new combos trying to configure a cockpit. They've all worked together. .

I'm thinking the diam of the drop part is pretty standard. I'm sure someone with moar 'sperience can confirm/correct that.

I wasn’t sure it would/should be an issue anyway but I only asked as when I was adding stuff to my basket on chainreaction it had options for sizes which has totally confused me.

Unless your bars are something weird like the Soma Gator which is made for mtb controls, they should all be the same size.

For my gravel build I’m using DMR moto digger tyres, they roll surprisingly well on road as well as being super grippy for off the beaten track. 26” x2.1, not too wide but just enough.

I used those in 2.35 on my 26in gravel build.

Pics of the build?

Hey everyone. I'm new to vintage/ retro bikes. Was recently given a 88' Shogun Trail Breaker in really great shape. Was looking to convert it to a bikepacking/ gravel rig. Any tips would be appreciated.

Stick with the cantis / u brake to make your life simple. Get some friction bar end shifters and some nice dirt drop bars. Then get a really long stem - a nitto technomic or dirt drop will work for a threaded headset. If you're running threadless a VO Cygne stem will work well. Get some used drop bar brake levers, cables, housing and you're off to the races.

May I ask why you changed the front crank? I am doing a similar build, and wondering if I might need to change my crankset as well.

I'm converting my stock 1993 Specialized Rockhopper Sport to drop bars. I have Shimano Exage front and rear derailleurs and ordered some Microshift R473's after reading your post saying they are compatible. (Fingers crossed that everything works!). So is there any specific reason you changed the front crank? I believe my front chainrings are 26/36/46 and the rear cassette is 11-32t if that is relevant.

Thanks in advance!

I've changed the crankset only because it was in my parts bin (no money spent), I liked this one better and this one has less teeth to compensate for my less the stellar physical condition...

If you're not planing on super steep climbs and if your crank is in good condition than you should keep it, and you also get a bonus of having a full Shimano Exage build, instead of a mixed bag of parts.

What I strongly suggest is to try a lot stem lengths until you feel comfortable. I started with a 90mm and ended up with a 60mm from the parts bin. The same goes with the tire choice, I started with 2.0" Schwalbe and ended up with 2.35" Mavic Crossroc from another bike.... and this is all part of the fun of playing around with this old bikes.

I'm looking forward for some pictures of your build!
