Shimano 105 is like SLX right? Any bargain group sets around? Minus brakes...!
ta!
Shimano gravel/road stuff tends to be 2x only, if you want 1x then it's SRAM stuff you need to look at. Apex-Rival-Force.
I think I want to use a double. For MOAR PWR interval sessions and turbo etc
.
I can't think of a reason to want a single ring on a gravel bike. It's not like you've got a fat back tyre getting in the way of things.
I’ve gone from a 2x9 Shimano drivetrain to SRAM 1x11 on mine - mainly to get hydraulic brakes. On most rides (Peak District area) I haven’t had a problem with running out of gears, but there have been a couple of climbs where I’ve been off walking, where others in the group on 2x kept riding.
I wouldn’t bother with SRAM either. The indexing mechanism in my shift lever broke and you can’t just replace the lever, like on Shimano - I had to replace the whole unit (lever, hose & caliper). Luckily sorted under warranty, but tbh, dunno if I’d go 1x or SRAM again.
guess itdepends on the terrain...? Cyclocross/ off road more, 1x11 is great... but i use my gravel bimbler more on road with the occasional gravel/ tame off road bimble.
Anyhow, looks lie 105 is the one to go for to replace what i have. may just go for a new chain cassette and jockey wheels, freshen it up a bit (plus new cables and outers etc)
I think the perfect gravel gearing is 46/30 front chainset with either 11-36 or 11-40 cassette out back depending on where you live.
Trouble is Shimano don't yet do a 46/30 chainset, FSA, Middleburn etc do, or Absolute Black do aftermarket chainrings that fit Shimano chainsets.

I ride my gravel bike more off road than on so 34 x 11-40 is ideal. if i was to ride it more as a road bike I'd either get a road bike or a compact chainset.
I haven’t had a problem with running out of gears, but there have been a couple of climbs where I’ve been off walking
Eh? Surely having to get off and walk is the definition of running out of gears?
You've discovered a new drivetrain niche there, Gravel Groupsets.
Personally I think 1 by is a good idea with say a 38 front and 11-40 rear, gives you loads of range and can be done with Shimano or SRAM.
Hi Steve,
You may have spotted benefits that I have not, care to share?
Smiffy
Simplicity, equal gear range, no front mech to get filled with fine gravel dust and **** up, aesthetics, clutch mechs.
A side note, I run 38t up front and 11-36 on mine and haven't run out of gears on road or gravel path, for full on off-road I have a MTB or two. Done 200km plus rides on that set up no worries.
