Otherwise if you can get into York this evening, I'll have a look at it for you.

Where abouts in york?

You have a PM

I am going to put this in here to avoid making another thread as I have made enough allready.

I have got a puncture today and its on the inner side, do all wheels have these holes on the inside of the rim? Even with double rim tape on there it seems the inner tube has pushed through some how and obviously got a puncture, not made a hole in the rim tape, but its a problem anyway and needs sorting.

Also do some rims have gromets in them or something to stop inner tubes from puncturing through the holes in the rim?

Don't worry about asking for advice Will - that's how you learn. We've got a rota going now though for answering your queries

First may I recommend 2 good sources to give you enough reading to keep you off the bike for weeks.

Richard's Bicycle Repair Manual will answer 90% of your maintenance queries http://www.amazon.co.uk/Richards-Bicycl ... 502&sr=1-3 and,

Sheldon Brown's website http://www.sheldonbrown.com/hb.html which will answer the rest. There's a lot of information in both so treat them as 'library' resources not bedtime reading. Sheldon Brown has a link to an article on Rim Tapes here http://www.sheldonbrown.com/tyres.html which goes into some depth on the subject.

However, to answer your question very quickly, rim tapes serve a few purposes one of which is to prevent the tube being forced down the spoke holes or against spoke nipples, under high pressure and puncturing. If you suspect your puncture was caused by this you've either got no rim tap, damaged rim tape or some other tape that isn't strong enough for the job.

Thanks, will read all that later when I have some time, just going off to halfords now seen as its the only place open to see what rim tape they have, we just had some cheap white rim tape and also under that some other black rim tape, hopefully halfords have something better, need it for college tomorrow, but I will hopefully get to a better shop tomorrow.

...to add to Paul's comments (don't worry, there isn't REALLY a rota ) the other possibility is that the tube had simply been installed twisted, and although the puncture might be on the inside of the tube it may have been that the inside of this bit of tube may have been against the outside of the tyre, if you get my drift. Check the tyre VERY thoroughly for holes and - especially - for anything still stuck in it.

Another excellent online resource for repairs stuff is the Park Tools website at http://www.parktool.com/repair/ - there are lots of how-to step-by-step tutorials.

Tube cant of been twisted surely would not last long? Must of gone 400-600 miles since the last puncture, anyway what we have done now as halfords just has crap rim tape is used the same double rim tape, but under that we have put some of this blue elctric insulation tape or something like that so that should hold. Will go into the LBS tomorrow see what they have.

It is really stressing I think my tyre is going down allready, my dad must have caught the inner tube and I would do it too, I have read guides on how to remove tyres and all that but still cant do it. I know I would be fine on the club rides as I have my inner tube and all that and I am not alone so will be able to get it repaired then.

Will,

Long range diagnoses are a tricky thing. But *assuming* you do have a rim tape issue I thoroughly recommend the Velox stuff http://wiggle.co.uk/ProductDetail.aspx? ... Rim%20Tape. Selby Cycles should stock it. Its adhesive backed so won't slide around on the rim and made of a tough woven. It comes in two widths and I guess you'd want the wider (the narrow is for *really* narrow rims).

Re getting tyres on and off - best learning comes from watching a master craftsman in action - one for the clubrun?

R

Is it the same as the tape onthis page?:



Also is that Continental Easy Tape any better? I notice it costs more.

The 'easy' tape is just slightly thinner and snugger fitting. Some rim/tyre combinations are really tight and using a thick rim tape makes the tyre almost impossible to remove/fit by hand. I put some on Gill's road bike for this reason and it made a, small, difference (difference between breaking tyre levers and not). I use the stuff Rob mentioned for all mine though. The only one I don't get on with is the Michelin plastic, super thick, band. It's difficult to fit and get off and is too thick for most road tyres. If you split it, it can also develop really sharp edges.

The Velox stuff wont make it harder to put the tyre on and remove it right?

Right

Incidently I've only just looked at your link. That Velox stuff isn't the same as Rob advised. That looks similar to the Michelin stuff. Stick with the cloth one.

Yea I noticed, could not look at the wiggle link at home as it wont load.

So the cloth one will still be stronger than the rubber one and not make it any harder to remove the tyre and put it back on? Also wont it get more flexible in wet conditions?

Cloth one is tried and tested, it's fine.

What size would I need 19mm?

I am thinking of going to a LBS to see if they have cloth rime tape in as I need it for tomorrow I think.

At the moment my tyre has a couple of layers of electric insulation tape then the 2 rubber rim tapes but my tyre was rock hard last night I am sure its slightly softer this morning but it has got me 10-11 miles to college
