Top tube bag – which ones are good?
Need one to be able to charge the GPS on longer days out, the type that fit on the top tube just behind the stem. Anyone using these and can advise on things to look out for/which ones are waterproof/ don’t interfere with knees when riding etc please?
ThanksPosted 2 years ago
They have a habit of wobbling around a lot.Posted 2 years ago
Yeah I know, some don’t hold very still especially with a power bank in there that’s 250g or more. There has to be some good ones though….Posted 2 years ago
I have an apidura one. Decent, doesn’t wobble if you put a layer of duct tape or similar under the top tube straps and do them up super tight.Posted 2 years ago
The best one I’ve used is the Revelate one, the others I’ve had have all wobbledPosted 2 years ago
I have an Altura which is nice and slim so doesn’t interfere with knees. Very stable when strapped up. Not 100% waterproof though.
If you have skinny steel tubes be careful because most bags Velcro straps are designed for fatter tubes and will not close.Posted 2 years ago

I have an Apidura which needs careful positioning and herself has a MissGrape which seems much more stable.Posted 2 years ago
If you just want to hold a power bank then just get a small one and tape it to the stem plugged into the GPS. A bit Heath Robinson, but far easier, and won’t interfere with your knees!Posted 2 years ago
Hmm my revelate one wobbles. I must be doing it wrong.Posted 2 years ago
Revelate for me too, 5yrs old now on 2 bikes, no wobbles. Although trying to find a way to stop my tools/CO2 clinking on rough downhills is proving surprisingly elusive!Posted 2 years ago

Thanks everyone, looks like the revelate is the way forward.Posted 2 years ago
@njee20 – I had thought of that but….it rains lots here 🙂
Any suppliers of revelate in the UK?Posted 2 years ago
Google search just seems to bring up overseas sellers
I wrapped a length of old innertube on the frame before I velcro’d the top-tube bag to it, stopped the slipping.
Big-scot-nanny, I wrap my clunky tools in that thin, foam like sheeting you get as parcel padding, that stops the clunking.
For a partially filled frame bag I scrunch up a bath sponge and insert that into the frame bag, it fills the space for no real weight added.Posted 2 years ago
Nice one scotroutes, on the site now !Posted 2 years ago
Is that your place or just somewhere you know of?
Not mine but I’ve bought a bit of stuff there and can recommend. If you cant see what you want send an email as I know there is more on the way.
For those suffering from the droop..

You can fit top tube bags inside the frame as well as a sort of mini partial frame bag.
Whether or not a top tube bag wobbles can be down to tube profile: an Alpkit bag on my Solaris which has a flattened shape to the top tube is fine but on my Pompetamine which has a round tube it flops around*.
OP, note that USB connectors aren’t waterproof so even if the powerbank is in a bag you’ll need to deal with that. Also have a look for “angle up” and “angle down” connectors, these have the plug set at right-angles which can reduce the strain a standard connector puts on the soldering holding USB socket to the main board of the GPS. With my Oregon I have to use one as there’s no room for a standard connector when the device is in the mount.
* Genuinely no double-entendre intended.Posted 2 years ago
Consider shortening the velcro straps too. They’re invariably very long but it makes pulling them tight a lot more difficult. I have a small Alpkit one which suits me for shorter bag-free rides (tube, CO2, tyre levers, multitool).Posted 2 years ago
I’ve no recommendation for a bag, but these Polaris straps are great for attaching things like batteries.Posted 2 years ago

I am happy with my Topeak Fuel Tank
+1. very happy with mine aswell..Posted 2 years ago
Topeak Tri Drybag. Narrow enough not to be kneed, easy access flip top (no zips), I haven’t properly tested it for being waterproof, I’m usually sheltering at home before then 🙂Posted 2 years ago
I’ve tried a few, being a triathlonist and all that.
Best one I’ve used is an Altura Sprint energy pack.
Sits very stable. Zipped. Good capacity.
I use it mainly on mtb for carrying tools and it is rock solid as the straps are a good length and elastic ated so you can get it nice and tight.
Cheap too.Posted 2 years ago
I’ve a couple of different size Alpkit ones which are great and don’t seem to wobble. As noted above, a lot is maybe down to tube shape/size. You can work wonders with a tube of seam sealant to add DIY grip dots on things, then use the rest of the tube for reinforcing stitching, etc. Good for wear points/seams on waterproof shorts too.Posted 2 years ago
