Is it normal for spokes to poke through the rim this much?

Welcome to Bicycles SE Without being pedantic you’re seeing the top of the nipple making an impression on the rim tape. It might be OK. Lift the tape/liner with a blunt edge and have a look under. As ...

I have a bent aluminum rim on my Merida MTB. Is it damaged beyond repair?

UPDATE That aluminium rim is cracked. You should scrap it immediately. The crack is a weak point and if you try and straighten it, the crack will widen. The air pressure in the tyre will lengthen ...

I have a bent aluminum rim on my Merida MTB. Is it damaged beyond repair?

When dealing with dents like in the first photo only… I get dents like this all the time. I straighten them out with a crescent (adjustable) wrench. Start with small movements to get a feel for how ...

Bike too large, if I change the wheels to a smaller size will this lower the height?

There are several issues worth addressing. The frame is too big, when I stand on the bike, off the seat, my toes only just touch the ground. I'm not thinking this is safe to ride around London. When ...

Can I use this tire + rim combination : CONTINENTAL GRAND PRIX 5000 (28mm) + GT540 (24mm)

Its clearly not-recommended by the rim manufacturer. On top of that, the tyre has come off for you proves that its a bad combination. That it is only 2mm is immaterial - it came off and could have ...

Can I continue use abraded rim?

The rim is toast. Even if the sidewall is structurally sound (no cracks or anything) that’s too little remaining material to safely retain a tyre (i.e. to properly seat the tyre bead). The tyre ...

Can I put a 700 x 35c tire on a rim that came with 700 x 30c tires?

I’ve used 35mm tyres on DT Swiss RR415 rims with a mere 14mm internal width. The main problem was that at low pressures (<3bar) the tyre tended to “collapse” sideways in sharp turns. Very high ...

Bike too large, if I change the wheels to a smaller size will this lower the height?

Being able to touch the ground while sitting on the saddle is not a criterion. When you stop you are supposed to move in front of the saddle. If you are in front of the saddle and unable to stand on ...

Exactly the same thing happened to me with a brand new pair of DT Swiss ARC 1400 wheels that came as standard on a new bike. Both of them blew out within a few days of each other – thankfully not ...

Yes - start by lubricating all the nipples with penetrating oil, and then back off the red areas and tighten the green areas, a half turn at a time. As the wheel comes back into round, check ...

Are my rims "tubeless-ready"?

No, these do not appear to be tubeless compatible. Tubeless compatible rims have sidewalls that are much shorter than yours. These are necessary to create an area for the tire bead to lock into. ...

How can I treat small glass cuts on my bike tyre?

With some kind of protection inside the tyre, the best you can do is check the tyre occasionally. The tyre doesn't have to be airtight (assuming you're not running a tubeless setup, and it sounds like ...

New wheels: WTB KOM Tough with 32 spokes sufficient?

My opinion, as a huge fan of 36-spoke wheels (the only case I accept 32 spokes is a 559mm fatbike rim and in this case the spoke density, spokes per inch of rim, is the same as for 36-spoke 622mm rims)...

Access hole opened near spoke on Dt Swiss 1600 rims

I would fit a new rim tape that is sized for your rim. That's probably 622mm, and of a width to suit. You might choose to peel the existing tape off, but there's some chance its stuck down with ...

Bike too large, if I change the wheels to a smaller size will this lower the height?

No - this bike cannot take smaller wheels Based on the photo - you have rim brakes on an 80's or early 90's road bike. The height of the pads has a few millimetres of adjustment, but not enough to go ...

Does "ETRTO" apply also to tyres?

Yes! We can refer to the tyre size and the rim size using millimetres by the ETRTO system. Note that the rim diameter comes first in it's designation, while for the tyre we put the width first. So we ...

Do you think these are the same wheel for all intents and purposes?

I'm assuming that the question is about the whole wheel, not just the rim. The rim dimension is the same, so the same clincher tires with tubes do fit. Tubeless tire compatibility is a complex subject ...

Do you think these are the same wheel for all intents and purposes?

Both rims are 622mm diameter, with an internal rim width of 19mm, according to the numbers on the label. They will suit exactly the same widths of tyre. Neither appear to have a brake track, so they ...
