A Few Small Problems

fiestaman

Hi, have a focus cayo 105 and have 100k up on it now. thisevening half way through the cycle when i went below gear 5 the chain started rubbing the inside of the big cog on the front. can this be easly fixed or will it always do it on a 10 gear casette. also lot of lads are telling me i should get the bike set up for me, is this worthed. ive just got clip in shoes and this is the 2nd run with them and im getting a little burning sensation on the sole of me foot (ball of me foot) where im clipped in. do they need adjusting or just breaking in?

Gear issues could be due to gear cable stretch, normal with a new bike. Probably just needs a quick tweak. Lots of tutorials on the web, or take it to a mechanic.

Shoe issues read like "hotspots", quite common with stiff soled shoes, partly the price you pay for efficiency but usually goes away after you've broken the shoes in to your feet (or vice versa). Try to relax your feet in the shoes, and wiggle your toes regularly if you can.

My SIDIs were evil for the first few hundred kms (hotspots and cramps) but they're better now. Or else all the nerves in my feet have died.

My own Sidis were none too comfortable either at the start, feel perfect now.

I've a 105 triple, It's new too as you know.

Mine needed a little adjustment of the cables after the first few spins. It still rubs the front deraillleur a little if I have a crossed chain, i.e. Small chainwheel(front) and the small sprocket(rear), and vice versa Large chainwheel.....Large sprocket.

It will only rub very slightly when at the extremes like on the 1st or 10th sprocket; your machine should not do it in the centre of the casette. It would be well worth getting this set by someone who knows what they are doing if you can't do it yourself.

Can't help you with the shoes I'm affraid. I've got a pair of adidas SPds and they were broken in after a couple of spins.

You shouldn't really cross your chain as it leads to excessive wear to the chain, cassett and crank. Instead of going small to small or big to big etc move up/down to the centre gear on the crank and adjust the back derailleur accordingly to get the most comparable gear. This will make your bike run smoother and give increased life to your drivechain.

Your Shimano system is also capable of half-shifting or "trimming":
