sorry - can't really comment on what's wrong with the Michelins as I don't recall any issues when I rode their precursors.

when you say they "kick" - is this as you go round a bend?  I'm thinking here that it's the larger knobs on the edge "catching" on tarmac doing that. when you're riding in a straight line then it would be fine as you're on the smoother centre tread.  you probably wouldn't see any issues like this off road.  maybe you are just seeing something that isn't an issue but as they are very new to you, and a different pattern to the old ones, then it's a familiarity thing.

as for bulges - I'd always be suspicious of bulges in tyres but that will depend on how large and where.  MTB tyres are never fully smooth near the rims ime and it's maybe that they just need to settle in.   but if it's a bulge that is really protruding, then I'd question the build quality and get them replaced.

and I'd always go for folding tyres....

I should get my new steed by the weekend - looking forward to getting on the Downs on that

Hi FB,

I think you may have done this somewhere already. Could you describe your MTB setup for Xterra? I'm considering some MTB duathlons over winter.

Posted this on another thread the other day, but it may have gotten lost in the recent IT melt down, but....

Picked up my new Fixie yesterday. After putting it all together I adjusted the chain tensioners so there was about 1/2 to 3/4 of inch play in the chain. But after turning the crank maybe half a turn, the chain was taught with no play at all. A further turn of the crank, there was half inch of play again - and so on. Now is the crank is out of alignment, or is it a partially worn chain.....or me just being crap??

have you checkd the chain to see if you have a stiff link somewhere??  if that's not engaging properly that maybe the cause

Just had a good look - doesn't appear to be any.

Probably just slightly out of alignment Raf, or maybe the chainring isn't perfect - it doesn't take much to take up the slack.  A partially worn chain would do it too - it only needs one slightly worn link - if it's on the chainring there won't be any slack, somewhere between chainring and cog and the chain is ever so slightly longer which gives you that half inch of movement.

You don't want it completely taught, it'll wear very quickly that way.  Set it to half an inch of play at the tightest point, if you have a bit more than that at it's loosest it won't be a problem, the chain isn't going to come off.

Which fixie did you get?

Thanks both - I've adjusted it to about half an inch play, so it should be ok.

I bought a State Bicycle Co. Matt Black 3. Its nothing fancy, just a bit of fun for running around on - and so far I'm loving it! Although I have been challenged by my local tri club to do an Olly on it next month - guess I'll have to attached the back brake before then

If you've set it up with a single speed freewheel you're OK (if a bit mad if it's anything other than a flat course) but fixed gear bikes are banned usually.

Its got a flipflop hub, so I can set it with a freewheeling hub. There's the odd up-flat - but there's a bet involving a couple of pints, so it should be worth it!!

Bike Numpty Question... 

Wife is tempted to try a sprint tri in September...  Currently she has a 3 speed shopper bike - which seems to be made of heavy duty steel lead lined suspension...  tyres made of iron...  ie it weighs the best part of a tonne!!!  And has a basket and pannier fixed on!


I was wondering round Halfords and Decathlon I saw some reasonable priced road bikes  they seemed a better idea of riding one of them than dragging her ...  are the geometries now all for men or is their a women's range or would she happily manage on a small mens frame?  Just feel that it might be a slightly better option on a 15mile cycle trip.

26/07/2013 at 20:11

Some makes have a specific woman's range, boardman do but not sure at what point they start in the range. Probably be fine on a mens frame of the right size for the time being, until she gets hooked and upgrades 


The Decathlon B'twin triban 3 gets great reviews and has a spec hard to match for the price. 

26/07/2013 at 23:19

Rocco that is the one I was think of for her indoors

27/07/2013 at 09:24

My wife has the triban 3, its a great bike I bought the triban 5 earlier in the year but I can't see much difference between them apart from £200, we've upgraded the wheels to shimano's but kept the old ones for the turbo. Highly recommended bikes

At that price range there's never much in it, the Decathlon bikes have carbon forks that supposedly take some shock out of the road, the best thing to do is try them and see which one fits you best, it doesn't matter so much about price and spec as long as it comfy for you and easy to operate

28/07/2013 at 09:14

I would go for the Decathlon as it carbon carbon fork rather than steel, is slightly lighter and has 8 speed rather than 7. Te only main difference I can see is that the decathlon has a triple where as the halfords hike has a compact double. That would just come down to personal preference though.

I have a Scott CR1 Pro as my best bike. Recently it's developed a click. 

every time the left crank goes over the top and gets to about 11 o'clock (looking from the left) it gives a single click. 

Could this be time for a new bb? It's 2011 model, so I've had it over a year. 

Anytging else it might be? I'd say its crab related. Only ticks in time with the crank, wheel speed or gear makes no difference, it's cadence related
