I would like to replace my current skewers but I don't know what size I need.
my hubs are ft. 100 and rear 135.
my bike is a hybrid with 700cx35 tires.
I been looking on ebay an seeing this "Effective front hub width: 100mm, Effective rear hub width: 135mm, suitable for Road & MTB "
what does "effective hub width mean?
one us dealer I ask said that 100mm/135mm were the length of the skewers.
does this mean that these will fit my hubs or are they to short? do I need longer skewers?

thank you in advance for your help.

Be wary of that dealer in the future.

The 135mm and 100mm refers to "OLD" or over-locknut-distance. It basically means your fork spacing, since your lock nuts need to fit between the dropouts. However, the axle extends past that so it rests in the dropouts, and the skewers extend past that so they can clamp down on the outside of the dropouts.

Just buy skewers meant for 135mm hubs and 100mm hubs. While there are a variety of OLD, there are only 3 common ones that use skewers. 100mm, 135mm and 130mm. If a product is advertised to fit one of these sizes, it is meant for that size OLD, even if it isn't clear what the heck they're measuring.

Buy skewers with an internal cam mechanism, the kind where you cannot see the pivot, such as those supplied by Shimano. This type will clamp much more firmly with a given amount of lever pressure than the external type. If you can see the pivot point it is the external type and I recommend that you avoid them.

Check Velo Orange for resonably priced internal cam skewers.

+1 on the internal cam skewers. Front skewers are almost universally sized for a 100 mm OLD hubs. Rear skewers are made for either 130 mm (road) or 135 mm (MTB, Hybrid, etc.) hubs although many 135 mm skewers thread down far enough to fit 130 mm hubs. Despite the nominal size (100 mm, 130 mm, 135 mm) all of the skewers are really long enough to clear both the hub width plus the dropout thickness.

Yep. Internal cam are SO much easier to operate. External are much harder.

I'll say I prefer shimano. Well made, and smooth. Just my opinion...
