Having purchased my new bicycle a Cannondale 29er Mountain bike but leaning more towards road and a bit of trail, I need a rack for it. Any thoughts /experiences on seat post racks vs regular rack? I would be putting a single bag on it and not going touring etc.

Thanks

Does it have rear suspension, if so you probably can't fit a standard rack?

Rigid rear end
Haha, technical term, ' Hard tail' 😁
Conventional rack, will take more weight but look like an old man's bike.
Seat post rack, trendy but not particularly practical, don't load it with lots of shopping (wine)
That's my opinion 😎

I've got a 29" full sus. When I had a Fiamma rack on the back of my previous panel van, I found the bike was so long it would roll of either end of the rail while I was trying to clamp the seat. The 2.6" tyres don't fit in the channels either. Fiamma do a longer rail, which helped a lot.

The new van has a Thule rear rack. The rails are curved, a bit longer and the stop blocks are bigger, so it's much easier to use.

Edit: you're taking about pannier racks... Ignore me.

I've seen these but wondered whether it would flop about when pedalling? Not a problem then?

Hi Jon..I've been down a similar route you are on so I'll relate my experiences in case some of the points help..
First off is the bike frame equipped with specific mounting points for panniers or rack..if it is you should be able to buy a frame to fit...
If its not then it depends on frame material and possibly whether you have a dropper post etc..
I bought one of the seat post type racks as a starting point but made some alterations...for various reasons...mainly because I wanted to carry a substantial load and my frame was carbon..I also had a dropper post..
Even if your frame is aluminium the clamps supplied Williamston certainly need lining with rubber if they are not to damage the frame...
The support stays supplied are adjustable but transfare the load to the frame ..I added a 2nd set of supports to transfare most of the weight to a modified back axle...
I didnt want any weight on the seat post clamp so added support there which transfared weight to the upper frame..
The original clamp been now rubber lined was just used for providing a bit stability and locating the whole rack..
All the above may mean a bit more if you look at the attached photos.. (y) :LOL:

Hi jongood

I’d recommend Topeak as a quality brand who do various options from very minimal seatpost mounted racks, through to much more substantial touring options with panniers.
If you’re planning on carrying anything more than a packed lunch, jacket, phone etc, then I’d look at something that has supports that attach to the seat stays.

Wow Andy! Got a bit of engineering going on there.

I do have mounting lugs but not looking to carry anything like that amount, I'm talking 2-3 hours mostly road with space to but a baguette or a flask, a lock and the wrong tool for whatever problem I have :giggle:

I'm now wondering about maybe one of these and one of these


Looking at the next says, they are made in Sheffield so also fits in with my trying not to buy Chinese stuff.

The ToPeak bags that go with this system: here? Edit: sorry, yes, there was a link. But to the smaller of the Topeak panniers. They do one with expanding side pockets.

Called RX BeamRack V-Type

That’s what I used. Quite small so only for a couple of nights away and for between B&B stops rather than camping.

The Topeak panniers I use are like these here

My MTB has a dropper post so here’s a pic of them on my road bike from Devon C2C:

My mate used a handlebar bag on the C2C. You can see it in the pic above.
It was awkward and horrible (in our opinions 🤪).
His was like a roll. Off the bike, load it up with clothes etc. then wrap it up like a Swiss roll.
Awkward to fit and secure. But he didn’t practice before hand and just tried it for the 1st time on this Reid’s.

mine has a dropper as well , but in touring mode its not really going to get much use as a dropper anyway...I was still able to drop my seat a couple inches anyway as the seat post clamp was only clamped very lightly...I used a modified clamp to take the load to the top of the seat stays...
to me that set up in the photo of the seat post clamp rack looks unsatisfactory for anything but a very light loads..
it needs some additional support imo..

The max weight is 7kg. So just clothes and not camping stuff. My Devin C2C was just a single night route but an additional night or two would work.
The design worked well for road routes.
But the weight is quite high so the centre of gravity moved up.
If the MTB course is windy/bendy, maybe that would change the handling and is a factor to think of.

Do you mean awkward to pack or to ride? I'm thinking it looks ideal fro the morning baguette run.

Thanks for that..ive seen the photos...its not really what I'm after..they look a bit formal.. I'm thinking a bag that could maybe take a tent or a sleeping bag..
I might even just try strapping a large dry sack to the bars rather than anything to rigid..
