Re: Stuck seat post....why?????

Brucey wrote:you don't say what kind of seat pin it is, but as others have said the seat tube is probably nipped up slightly at the top (the seat pin will probably be undersize vs the seat tube, such that the latter will deform when the binder bolt is tightened).

The type of seat pin has a bearing on what methods can be used to remove it. Suction wouldn't be on the list of things that I would try, BTW... :shock:

cheers


By 'suction' I think the OP was suggesting this as a possible cause - not a solution.

If it were the cause, the post would move up and get progressively harder as if against a spring. It would then return to its original position. I think suction is highly unlikely.

Virtue is its own reward

In education or at work one should thank people, that makes sense. I often do it when shopping too

The HC says one should signal, it does not say one should reward those who simply obey the law! That is the difference

As I wrote above: often they slow down or stop but then move off again before one is clear, steering towards one and just missing, you have experienced this surely

N e v e r trust a moton/terrorist!


Waving is not rewarding - it is simply acknowledging courtesy. How many times have you e.g. stopped at a zebra crossing and had an acknowledgement from the pedestrians? I've also e.g. (illegally) flashed traffic cops to let them in from slip road to motorway and received a wave of acknowledgement. Common courtesy, nothing more sinister.

if the obstruction is your side, you wait. Don't like so often happens just continue straight toward any oncoming vehicle.

It is somewhat distressing how many drivers seem to think this rule does not apply if the other vehicle happens to be a cyclist.


Strangely enough I have recently had several drivers wait whilst I rode past an obstruction on their side of the road. Needless to say they get a grateful wave.

Having returned to cycling afer a long absence, I have been caught out a couple of times, where I was surprised to find I was using a higher gear than normal on my regular route. It was only when I turned back that I realised I had been benefiting from a tailmwind!

Many (most?) people do but with SPDs I've never found I've needed to unclip significantly earlier than if I was on flat pedals. In the rare instances where I've unclipped one foot as I've come to a halt & the bike has gone the other way (gust of wind, movement of child in seat or tandem stoker behind, etc.) I've never failed to get the other foot out and prevented the bike from toppling.

Look type cleats are, potentially, a different matter. I'd not used them for 15-20 years & had forgotten how much more fiercely they grip until I'd been doing some track riding at the velodrome in the last year or two.

Even Looks are so much easier than the old slot cleats with tight toe straps of the "Olden Days". Who else remembers the having to do a hard stop & then trying to reach down & loosen a strap, to let you get your foot out, before the bike had actually fallen over?


I have had a couple of near misses with SPD's, the main one being when I first went clipless and used the SH51 cleats that came with the A503 pedals. I almost gave up, but then read about the SH56 being much easier to release, so I tried them and they are fine. I've had two instances of unclipping one side (as I come to a halt - I don't unclip in advance, same as you) and then falling towards the opposite side, but in a panic the SH56's even release under upwards pressure, so I've never (yet) failed to get my foot out.

Re: pedals change

Brucey wrote:nearly all pedals fitted to adult bicycles (in the UK, a few BMXs being the primary exception ) fit to the bike using RH/LH 9/16" x 20tpi pedal threads. This means that you can fit almost any pedals to your bike. Just remember that the LH pedal is on a LH thread, i.e. you turn it CW to unscrew it.

However shoes that accept cleats come in two main flavours; 'two bolt' (for SPD cleats etc) and 'three bolt' (for LOOK cleats etc). If you are just starting out I would suggest a set of two-bolt type shoes and (say) some PD-A520 pedals, or (easier yet) PD-M520 pedals (which are double-sided). These shoes/pedals have the great advantage that you can walk in them, unlike three-bolt shoes/cleats.

Modern bike pedals (of all types that provide retention) may require a little familiarisation before you can get your feet in and out. Some are easier than others.

cheers


Just to add to this good advice; if you do go for SPD, buy the SH56 cleats which will release in any direction - much easier for a newbie, as I found out very quickly!

Could the OP buy the bike and send the fork to Upgrade as per the recall?

The advertiser specifically mentions the recall in his ad.

I don't know enough about bikes to comment on this one, but to me the advert comes across as genuine and if I were in the market for a reasonably priced road bike, I'd definitely take a punt at this one. It must be worth it for the groupset alone?

Re: Giant Revolt 2 OR Dawes Galaxy cromo?

They look to be two completely different types - the Giant is a cyclocross and doesn't look to have any fittings for guards or panniers and the Dawes is a tourer with both guards and panniers already installed.

I guess far more experienced people than I will be along soon, but in the meantime, looking at what you want the bike for, I would think of the two, the Dawes would be far better suited.

Re: Anyone recommend a cycling mitt with decent padding?

Funnily enough, I've been looking at buying a pair for the last week and have just this morning pulled the trigger on some Louis Garneau Air Gel+ RTR Mitt, from Evans at £24.99, posted.

I also suffer from numbness and pins and needles, so I'm hoping these will help.

Looking at all the reviews on line, there doesn't appear to be one stand-out recommendation. Its all down to personal preference, I believe.

That said, lot of what I read suggested that a change in bar position or even bar type, was required. I'm going to see how I get on with the gloves before exploring more dramatic changes.

Anyway, hope you get sorted. Would be good to get some feedback on what you buy and how you get on. I'll do the same.

Re: bicycle pump lubrication

The best lubricant for a leather washer is neatsfoot oil.

Silicone oil is ok too, but should not be allowed to migrate to any area of metal to metal contact, where it will cause galling and excessive wear.

Re: Help - have I messed up my Shimano hydraulic brakes?

Thanks to all who replied.

I took the bike in to Evans this morning and they simply bled the front brake, which has restored it to better than new! Good service from Evans.

Front brake is most efficient brake. Back brake also tends to increase wear on the rear tyre as the action of braking tends to lift the weight off it so it tends to slip/skid.


I'm sure that's true, but I did my cycling proficiency in 1959, when we were taught rear brake first, then front.


Times change and the reality is that the front brake should be doing most of the work. Seriously, for your own safety, practice feeding in the front brake first - you will stop faster and in better control.


I'll certainly give it a try once my brakes are sorted. Thanks for the advice.

yes but it is arguably pointless unless you can buy spare parts. Shimano don't sell the seals etc that you might require. A typical EV techdoc for a hydraulic MC looks like this

http://bike.shimano.com/media/techdocs/content/cycle/EV/bikecomponents/BL/EV-BL-M988-3074_v1_m56577569830721147.pdf

and most of them have fewer parts still.

Do bear in mind that your brakes should have a two-year warranty on them; I'd be asking the retailer about that.

cheers


Understood, thanks. I'll see what they (Evans) say.
