Re: Changing tyres to road tyres

Your wheels are 700c. That's the easy bit. But the width of 700c wheel rims can vary - the widest rims take the fattest tyres, while the narrowest rims take maybe 23 or 25mm tyres. Meaning -... not all 700c tyres fit on 700c rims. If your bike came with 45mm tyres they be on wide rims. Might be usef...

Re: Campagnolo BB Power Torque : What tools required?

If you undo/remove the LH crank bolt the LH crank arm stays in place. You need some kind of 'PowerTorque' crank puller to remove it, exactly like the one Campagnolo has never made.

Cyclus make one. Expensive.

Could you not have the BB shell faced to 68mm if it helps the situation?

Re: New T47 threaded bottom bracket standard

It doesn't really do anything that the current BSA threaded standard already does. But it might catch on in the case of metal frames. No, it doesn't do anything, except increase the overall diameter, allowing the bearings to be appropriately scaled up for bigger modern axles. With modern external B...

Re: Tri/aero bars on Trek Emonda SL6 pro

If your Emonda puts you in quite an upright position the savings with aero bars would not be half as good as on a bike with a low front end. Aero bars might also make handling a little tricky in the case of high front end.

Re: Cannondale headset

Thanks Bruce, am I right in assuming then that the crown race on my bike currently is part of the forks and not a seperate piece? Or is it possible it should come off? yeah, it can be removed, but don't. It's not a crown 'bearing' race on which bearings revolve like in the old days. It is just a st...

Re: 26" mudguards?

They do look long. But a lot of front to back coverage is no bad thing. The metal stays are possibly universal size, meaning you get the same stays for both 26" and 700c mudguards. And they can be a sod to cut because being made of stainless steel they are strong. People tend to cut them with a...

Re: Alu Dropouts 130mm, hub 135mm. Going to be a problem?

Naah, like you say, its only 5mm. Whilst aluminium isn't steel, the alloys they make bikes out of can nevertheless stand just as much bending into shape - so long as you don't repeat the process. How else do you suppose they make it into tubes in the first place, and do that hydroforming thing, and...
