I don't have tt bars and am not looking to go down that route anyway so sounds like it'd be ok.

Is it something specific about your tt bars that made it less secure do you think?

Yes, I was using the velcro wrist strap round the bars rather than a cable-tied bike mount.

I've got a bit of foam pipe lagging on my handlebars and just put the garmin on that    very technical

Good idea that, what do you do in transition, just unfasten it?

I am looking at getting a turbo trainer for the winter (Tacx Satori) and also a GPS and HR monitor, probably the Garmin XT910.
I am not sure if I should/could get a cadence device for the Garmin so do not need to put a cycle computer on the bike. My current Specialised Dolce has got a wireless cateye with front wheel sensor. My budget is not bottomless but want to cover the basics. Oh and at the moment I am using a Lidl  HRM basic but it works.

So what combination of turbo and GPS/HRM do I go for?

Wotcha Steady   If you're looking at getting a 910 with HRM you might as well go for the associated Garmin cadence sensor too then you've got everything you need (and swim watch too) all in one package.

I think Polar have just/are about to release a new watch which does GPS/HR but can't remember if it is compatible with cadence sensor. Fairly certain it doesn't do swimming though.

Can't help with turbo. I have one ( Minoura HyperMag 1200) but it doesn't get used as often as it should for some reason

Any ANT+ cadence/speed sensor will work with the Garmins. I hear Decathlon do a cheaper one than Garmin. That said, my Garmin cadence doodahs work just fine.

Thanks Trogs and IronCat. Will now look at final amount of pennies in the piggy bank. I feel the need for some retail therapy and the best sort is sport related.

Front of bike was creaky yesterday, found headset loose AGAIN. Stripped it down, rebuilt it. The went to tighten stem bolts (5-8Nm). 1/4 tunrs on each until got to 5Nm on one, fine. Other bolt sheared before the torque wrench popped.

Did what I could (cutting/drilling) and have trashed the stem. Feck Feck Feck. New stem on order from PX. WTF does the headset keep coming loose?

22/08/2012 at 14:08

is it a PX one??  if so - cheap crap 

maybe the star nut needs replacing??  maybe it's slipping a bit??

The bike or HS? Both are PX!

22/08/2012 at 14:53

deosn't matter - cheap crap....  

get the LBS to take a look as I suspect the star nut is where the problem lies.  and as for shearing a bolt - cheap crappy bolts!!  replace with decent ones...

Sheared the screw at 5-8Nm ??? Whoever fitted it initially stretched it with way over 5-8Nm. Regarding the headset, which screws are you tightening 1st ? Do not tighten the side pair until you have taken all the vertical "slack" up with the star nut screw.

23/08/2012 at 12:58

5-8Nm is barely more than finger tight isn't it??

I have a spare stem, brand new, never used, cost me 35 quid I think. I THINK it's 100mm. That or 75mm. Pretty sure it's a Deda but would need to check. Any good?

23/08/2012 at 19:31

Yes FB, hey Dboy thats an inch difference The dimension is from the centre of the big hole at one end to the centre of the other big hole down the other end, in technical terms that is

Replacement arrived this morning - thanks anyhow DB. I decided that the thread wasn't too damaged on the old one so rode it last night (with new fasteners. 5Nm reached easily). Will change it out though for the sake of safety,

I have some thoughts on root cause, certainly as the old stem was tightenend it seemed to creep up the steerer.

23/08/2012 at 23:52

I'm confused now, is it the thread in the stem thats stripped or the screws that have sheared ? Stem "moving up the steerer" have you got the correct spacers in place ?
