the 'there's no such thing as a stupid question' bike maintenance thread

I think it's 8 speed, double chain ring on the front. My son is actually using the bike the last while. He uses it for commute mostly, and wants to put "heavier" gearing on it - he has big strong legs - the lbs telling him more costly as would have to change crank of that was the case.

Park Tool (and I assume other companies) do tyre boot patches that are compatible with tubeless tyres.

I'd be inclined to give them a shot.

Hi all

i'm in bother here. I'm pretty sure this takes an allen key. Had a 10 and 11 - no use. Bought a 12mm and still too small.

Before i keep buying allen keys for the next 2 weeks, any experience here?

I've got short keys up to 20, but need longer ones for this….

Sorry but what do you mean that you have short keys to 20? If that the size, can you not insert the long end of the key to figure out the size?

So update on the wounded GP5000. Having played about with trying to get it to seal for the past couple of days I've decided to play conservative and throw a tube in for the moment. I would give a normal patch a go, but the jury seems to be out on whether that works reliably. I'm off to the Ring of Beara next week, and have bad memories of one of the lads we did L'Etape with last year having to stop several times in a vain attempt to get a tyre to hold air. When I get that over I'll grab some of those Park Tool patches mentioned above and try them close to home.

Hi, I have an Outlander bicycle I bought in Lithuania, which is kept there. I would like to install a pannier rack to allow carrying more weight in some pannier bags of some sort (I see Lidl have some from tomorrow onwards), but have no clue about which ones I should get to install…

I see the bike has the small threaded holes over the rear axle which is I assume where the lower end of a rack would be bolted to. It looks like with the brake disc/calliper I’d need a spacer of some sort to get into the small holes on that side? I’ve seen some of them where the lower ends clamp onto the seat tray on either side, but would ideally prefer something bolted on which would look a bit tidier…

And as for the top side where the rack attached, is it simply a bracket to clamp around the seat tube? As I don’t see any fixed attachment point on the bike frame where the top part would attach.

Would this be an attachment point?

Yes to the last picture, a mudguard or carrier rack would normally utilize this connection point

experience, yes. Issues, no. Always worked ok for me

I have a handy press set that I could send up to you for a lend if needs be

Just bought an Elite Novo Force turbo trainer and now need to figure out how to measure my training rides. Elite suggest the Misuro B+ sensor but I have no idea if that's good or bad.

Ideally I want something that measures all the basics (including watts which my odometer doesnt) and if possible a free site or app that will give me an idea of what kind of session I should be doing.

You cant put a 28/700 on a 27.5 wheel as it wont fit the rim. Halfords,for example do a Marathon 27.5 X 1.65 for about 35euro each that would fit.

That's brilliant thanks I searched Halfords website earlier but couldn't find any 27.5. they look absolutely perfect

I’d say it warrants inspection but you might get away without a repair.
I’d throw an estimate of €250 out there but could be well off the mark

Mapdec Cycles make excellent videos, and this one should probably answer any questions you have related to press fit bb installation
