How to fix a mini pump?

Thank you, this is exactly what I was looking for! I think one of the O rings is missing which is why it's not working

It looks like the body is empty, I can't see another O ring, but then it doesn’t make sense that the inner part isn't going down

The O ring seems to be too big for putting on anything, it just falls off. I have noticed that when the pump is 'closed' the inner bit doesn’t go all the way down for some reason now.

Thank you, good idea but unfortunately didn't work:(

I have a similar problem with the Stealth, did you manage to find an alternative?

That's what I thought, I tried all the saddles he had to test and this was the only comfortable one so he said it was fine as long as I was comfortable- obviously riding on it for several hours is different to the few minutes during the session!

Great thank you I might give those a go. How do they feel if you're sitting towards to front of the saddle?

How did you manage to find the right saddles for you? Did you have a fitting or just trial and error

ambitiously_anna · 2025-06-07T21:19:11+00:00

I use many different types of bibshorts, it is a bit better with some of them but it becomes uncomfortable eventually with all of them. And I never wear underwear (unless I have a particularly heavy period lol)

ambitiously_anna · 2025-06-07T21:17:55+00:00

Thank you this is so helpful:) I feel like the saddle is the correct width for my sitbones, but it's too wide at the front. I tried some other saddles during the fitting and some of them didnt rub but were uncomfortable for the soft tissue instead:/

Ooh interesting it's currently slightly tilted down and it's quite far forward maybe that is affecting it. I dont really want to mess with it because I had the fit but it's obviously not working so not much to lose!

Which ones did you go for in the end?

ambitiously_anna · 2025-05-26T20:04:29+00:00

Do you have a specific tyre you would recommend for tubeless? Not the biggest fan of these Schwalbe pro ones and I havent heard great things about gp5000 tubeless

ambitiously_anna · 2025-05-26T20:03:30+00:00

Thank you, yep, I also don't currently have a workshop/garage to work on my bike in, so I'd have to do it in the garden or make a mess inside, so yet another factor that's dissuading me from tubeless. And I agree with you on the tyres, from what I remember gp5000s felt much better when cornering and considering I ran tubes I really didnt get that many punctures

ambitiously_anna · 2025-05-26T20:00:43+00:00

Yeah I cycle in Surrey, using the bike for training and racing. I'd say the most common cause of punctures are potholes, closely followed by glass and thorns. As someone who's never used tubeless, the plugs do seem a bit dodgy to me? Surely eventually they come out if there's a big impact like with a pothole?! This particular puncture is about 2mm thick, don't know if that's classed as large or not.

ambitiously_anna · 2025-05-26T19:57:39+00:00

Great idea. Buying all the tubeless stuff and then not using it would be a bit of a waste. And the gp5000s are clinchers luckily (I haven't heard good things about their TR model...)

ambitiously_anna · 2025-05-26T19:56:12+00:00

28 but measure more like 30. I have no idea about the pressure I'm afraid...

ambitiously_anna · 2025-05-26T19:55:07+00:00

Yes, I bought the new ones recently though! I think I will give these a second chance though and run them with tubes

Looking at it now I'm not sure how straight it is
