Cannot get carbon seatpost to stop slipping on aluminum frame

Have used carbon gripper paste inside frame, torqued to correct nM

Keeps slipping. Gravel bike

Original seatpost, no cracks

Collar seated correctly.

I've order a new seatpost clamp, will use paste and see if it works. Might have to over-torque the bolt

Wahoo v1 Roam battery replacement:

Is there anyone on the island who has experience/success with this?

My unit is only good for about two hours, which is effectively useless. I lack the fine motor skills to try it myself.

(Aside, the deterioration happened quite suddenly, from ~8 hours capacity to 2, over the course of the summer)

Thanks C.

I bought it used, so no, I didn't contact the manufacturers. I suppose I got my moneys worth out of it. I'll do a factory reset, perhaps there's something burdening the battery unduly, but I haven't been using many add-on sensors.

Nice unit, I would be a fan. The easy map zooming seems to be the best noticeable difference between it and my buddy's Garmin.

Yep, which is why I'm fully behind the Right to Repair movement 😄

The new seatpost clamp and tube of carbon paste seems to have done the trick. Huzzah

Also helps that the new clamp has a bolt with a hex head whereas original one had a torx head

Has anyone any experience of putting a child seat on a rack? I bought frame mounted yepp maxi for my wife's e-bike last week and it won't fit as doesn't have adequate clearance over the back tyre (I had been warned this might be the case but it's not an issue as I have just installed it on my commuter).

However I now need to try get her a rack and rack mounted seat. However, when I've looked online, most racks look like they have a weight limit of 25kgs. Considering a seat probably weighs over 10kg, I'd imagine I'll be approaching the weight limit soon. Does anyone have any recommendation on a decent rack that can take more than 25kg?

I bought a trailer, mainly to transport my ageing dog. The tow hitch (for attaching to bike) is too thick to allow the axle nut fasten. Is it usual to (a) get a longer axle or (b) get a make/female stud or (c) some other solution?

Cheap bike and trailer. Solution to match the already sunk costs!

I was cleaning the brake pads on one of my bikes tonight. When replacing the front, I inadvertently dropped the tiny spring clip (which attaches to the end of the bolt) and despite a lot searching, I couldn't find it. (They're ridiculously small).

Presumably it's purpose is to prevent the retaining bolt from shifting if it loosens? What are the chances of this happening?

(I replaced it with the back one in the interim as I'd prefer to have no rear brakes rather than no front ones).

That does sound like a typical stripped thread, all right. Are you using the same lock ring for the turbo and the rear wheel?

what speed cassette are you using?

Did you notice any metal swarf around the freehub threads on the wheel?

Yeah, I fitted a new chain and a 36 tooth cassette, way too big. So the chain is ~200 km old. I'll look around for the longer derailleur bracket too.

Free travel me asre!
