Alot of generations of Shimano and SRAM cassettes and chains are interchangable so what they are going to do likely has no negatives and doesn't stop you putting on a SRAM cassettes in future. What speed is your set up? I've used SRAM cassettes and chains with my Shimano groupset for years without issue.

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.

I got a snakebite puncture at the weekend on my rear wheel (tubeless). It didn't seal on the road and I had a mini-pump failure so couldn't put air in to limp home.

Having got home, I topped up the sealant and tried to inflate it. I lost pressure the first couple of tries (mainly around the rim by the looks) but after a while it seemed to hold air. Overnight it had lost most of the pressure however, and when pumping it up first thing in the quiet I could hear air escaping from the two holes shown when it hit about 60psi.

There's air coming out of both. I could patch the to one as it's not that big, but not sure about the one near the rim. Anybody got any advice? I'm a bit gutted as it's a brand new GP5000 with less than 250km on it. As a last resort, I could run it with a tube I guess.

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 Cycling, long long long time no see.

Not sure if this is the right thread (no stupid questions?) but I have an old Peugeot racer ('70s) that needs a good bit of work (new BB probably, maybe replacing the derailleurs, mayyyybe new wheels) and was wondering if anyone had some Dublin City suggests for a good bike shop to approach with a vintage bike.

I used to use Little Bikes on Stoneybatter, who I loved. But they have closed. Had good services at Bee Cycles on south circular probably 15 years ago at this stage, so my current plan is to go to him. Just checking in here first.

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….

Had this issue before, probably a 15mm. You could try 3 allen keys together, i think 5/6/8mm work, or you could try a radiator allen

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?

They're sockets. Won't fit up in axel

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.

Twas a 14mm

Stripped off the rotor and pulled out the non-drive bearing.

Got a 14mm from my socket set up the axel.

Does mean I may as well replace the bearing now. But no harm

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?
