Re: Scratch or fracture?

Press down hard on the chainstay. Does the "scratch" move? It doesn't appear to. As you have no mudguards that is a place stones and other debris will rattle arround so scratch isn't unusual there but its the length that is confusing, could your foot of slipped out and scratched it with t...

Scratch or fracture?

I've had my bike about 10 weeks now, and a few days ago noticed a knocking kind of noise. When I was out on it today, I noticed whenever I put a little bit of pressure on the pedals it appeared, light pressure or no pedalling meant no noise. When I got back I looked at the bike, and noticed either a...

This sounds like the cable could have stretched or as has been said not setup properly.
Does the chain rub on the outside or inside face of the front mech?

Rubs on the outside.

Re: Upgrading shifters

Humpy The adjustment needed is only millimeters,or it could be you're using extreme chain angles ie;big chainring and largest sprocket or small chainring and smallest sprocket,these will cause the chain to rub on the front mech cage,if thats the case limit you're chainline.If its not that then ther...

Re: Upgrading shifters

Thanks reohn2 and gbnz, I'll check out the adjuster. Is this something that should be moved slowly, i.e. millimeters at a time?

Also, just going back to the other question, if I got the 105 shifters (10 speed), would the original cables for the 9-speed be a straight swop?

Re: Upgrading shifters

IME low end Shimano kit changes just as good as anything else (which is very good),I'm wondering what your "gearing issues" are as you're thinking to upgrade just the shifters? I can get the 105 shifters new for £100 so that's why I'm considering that. I can shift up and down in the drops...

Upgrading shifters

My bike is a 2011 model, triple 9-speed with sora components, except the brakes which are 105's. Am I right in thinking that I can upgrade the shifters to 105 (5600), and not change anything else (and keep the same cabling)? I found the compatability chart but to be honest, don't really understand i...

Re: 2 small holes in new tyre

Wierd! Dont suppose it could be a wear indicator could it. Must admit I have not seen this before. Thanks, you're right. I've just been informed and looking at it, it does say TWI and a little ^ pointing to the hole, so Thread Wear Indicator it is. It would have been nice if they mentioned it in th...

2 small holes in new tyre

Hi all, Sorry I'm quite new to road cycling, so apologies if this is normal and will make you chuckle :lol: I bought 2 new tyres, continental gp4000s, and both of them have 2 small holes/indents. I just wonder if this is normal and where the mould is done, or if there's a dodgy batch. I haven't noti...
