Re: Coed Y Brenin

14 January 2015 - 6:38pm
I used to take my son and his various cousins/friends here maybe about 15-ish years ago, with a trailer full of bikes.

I'm sure I used to travel north up the A470 then turn left into the biking centre (excellent beans on toast/giant bowls of rice pudding!).

But when I went there a few weeks ago with my other half I found myself driving into a craft centre - the bike centre was on the other side of the road, a bit further up. And it looked a tad bigger and less rustic than I rememberd.

My other half thinks I'm going doolally in my old age - but I think the bike centre has moved.

Has it?

NB I was clearing out some junk the other day and found a leaflet for the Karrimor trail - which appears to show the bike centre on the left-hand side as you go north!

Re: Pumping up 29er 2.4inch tyres

I got a chance to try out a Giant medium sized pump on the 2.4's today as I punctured about 3 miles from home,it was a slow one and as it was going dark I decided to pump it up from 5psi to 25+ according to the little gauge on the pump,I had to pump it up three times on the way.
It's as well I didn't take the tube out as it could've potentially been frustrating.
When I got home I repaired the tube found a small thorn in the tyre but decided to check out the rest of the tyre and found two more thorns stuck in it .
One had pierced the tube the other not,so if I'd found one in fading light I may have just replaced the tube and thrown the tyre on thinking all was well
Just goes to show,always check
Anyway the pump worked OK

Welcome to the forum corey.
Nice vids but here's what you're missing out on https://www.youtube.com/watch?v=aeamDfgQVUQ
Not my own vid, but long ago before I got chicken and flogged the MTB, this was one of my regular haunts. The guy at the end got off lightly as hitting those boulders halfway down, I can say with some authority, hurts, a lot, when you come off

Lezyne HV Micro Floor Drive V2 ABS Pump from edinburghbicycle.com

The Lezyne HV Micro Floor Drive V2 ABS Pump lets you enjoy track pump-like performance from a lightweight portable pump.

HV stands for high volume. The Lezyne HV Micro Floor Drive V2 ABS Pump is a fatter-barrel pump designed to move more air per stroke into a high volume mountain bike tyre. You could use this pump to inflate high pressure road bike tyres up to around 60psi on a 'get you home' basis. However, for road tyres, we would recommend a high pressure pump such as the Lezyne HP Micro Floor Drive V2 ABS Pump.

When you need to use the pump, unscrew the ABS Flip-Thread Chuck that secures the hose to the pump's base in transit, screw the chuck onto your tyre's Presta or Schrader valve and flip the 3mm-thick stainless steel wire stirrup. You can then inflate the tyre, track pump style, with a foot on the stirrup.

Alternatively, you can use the Lezyne HV Micro Floor Drive V2 ABS Pump like a good quality hand pump and enjoy the fact that the hose connection frees you from the sometimes awkward action of holding a push-fit pump's head perpendicular to the valve it's connected to.
•CNC machined aluminium barrel, shaft, base and handle for light weight and precision performance.
•The pump's ergonomically designed T-handle manages to be very comfortable without protruding in transit.
•The pump's machined Flip Head Chuck is Presta threaded on one side and Schrader threaded on the other to ensure an air-tight seal for years to come.
•The Flip-Thread Chuck features an ABS Air Bleed System button. Once your tyre is inflated, press the button to release air pressure from the hose, thus reducing the risk of air escaping when you remove the Flip Head Chuck.
•Supplied with Lezyne Speed Chuckshould you prefer a push-fit pump head.
•Also supplied with needle valve for inflating footballs and so on.
•The 24"/| 60cm long rubber hose makes it easy to access your tyre valves.
•Supplied with composite matrix frame-fit bracket that mounts onto your bottle cage bosses.
•30cm long.
•Manufacturer's published weight: 150g.

'A compact HV pump design that brings floor pump function and power along for the ride. The aluminium barrel, shaft, base, and T-handle are custom CNC-machined for durability, ergonomics and reduced weight. A stainless steel wire foot peg provides stability while pumping. The ABS Flip-Thread Chuck and 24" | 60cm long rubber hose make it easy to reach both Presta and Schrader valves. Speed Chuck also included. Includes Composite Matrix frame pump mount.'
Lezyne.

'Fact: mini pumps are largely just a waste of time and effort. What you really need is a track pump that has been made small enough to carry with you in a pack when you're hitting the trails. Which is why we have been making good use of this battered and bruised old Lezyne Micro Floor Pump.

This pump has survived countless rides and lots of use and abuse and still continues to fill tyres quicker and with much less effort than any mini pump we've tried.'

Why Does No-one Want To Work As A Mechanic In Castle Douglas

12 January 2015 - 10:21am
Studio Velo in Castle Douglas is looking for a bicycle mechanic to repair £5,000-£6,000 mountain bikes and road bikes as well. The shop owner can find no-one at all. The Jobcentre arranged an interview for me as are the only one to come forward in the whole area. Now realise are good though not at this level at what I can do with my bikes and others which are usually are worth two zeros less! Feel it's well above my league as are the bottom end of cycling mechanics not the top echelon, was always taught my place in society. This is a genuine job offer, so here's the details;-

I soaked up the sunshine and the heat. (Envious)
I'm sure the descent is better to ride than to watch. (Not very exciting)

Congrats on the new toy John, I'm jealous
You'll be thankful of those wide bars when you hit narrow twisty singletrack. A short stumpy stem might benefit you there you too. I don't know what the fashion is nowadays but back when I were a younger lad us downhilling types all used that set up as it did really make the bikes easier to handle.
For those years I used one of the earlier versions of Blackburns Mammoth pump. Back then they were almost indestructible and did (from memory) a great job of inflating a 2.3" 26" tyre to 40 ish psi. http://www.evanscycles.com/products/bla ... p-ec018763
I would imagine that the newer version is better...assuming the suits at Blackburn have any sense.

Re: Trail Manners?

You could of course hear On Your Right as 'On the right' and move right, if necessary and you choose to take the risk for protection of kids' sake.

When overtaking on normal trails I don't suggest a side until I have the ped's attention, having had too many just pickup the direction and move there.

My take is that the faster vehicle behind has the Duty of Care, and Duty Not to Be A Reckless Idiot, just as cars to cyclists and cyclists to pedestrians in normal circumstances.

Thanks everyone for you suggestions so far.

I'll write a 'first impressions' post of the bike with some detailed photos when I've had another couple of rides on it.

MrJemm
The ETT is long @ 611mm (medium,17.5in model)because it's designed for straight 'bars,the seatpost in the photo is a non standard Easton EA50 with a bit more layback to get the saddle a little further back (without being at full rearward adjustment)with my favourite 1990's TurboMatic 2 saddle on top .
With the saddle in it's optimum position (for me nose of saddle 90mm behind BB and 89cm from pedal at BDC to top of saddle centre)from saddle nose to centre of stem h/bar clamp is 56cm with the standard 80mm stem.
Same measurement on the Vaya(s) is 54cm,but that's with compact drop bars so it's another 75mm forward to hoods.
The upshot is that the GL is in fact quite upright which isn't so bad off road though could perhaps stand another 20mm on the stem without it being a stretch or maybe turn the stem over in the -7deg position and see how things are with the 'bars a little lower.
I've sawn 25mm of each side of the extremely wide 720mm Alt h/bars and am considering Space Bugel bars for their backsweep,though I've not explored the stem length yet and or if the Alt's need more sawing off .
It's early days yet for me on a new bike and new h/bar type so I'm not sure other than the 'bars were waayy tooo w-i-d-e.

You were saying the other day how the TT lengths on these bikes are very looong, yet I spy a setback seatpost and fairly long stem. Is that because you went for the smaller size of your options?

I woulda suggested the Lezyne also. But anything to stop someone using those gawdawful cartridges TBH.

Or of course the kinda footpump I have for the dinghy, after all those tyres are about as hefty, hehehe.

You need a Lezyne Micro Floor Drive HVG Mini Pump. Easily mounted on the frame and much better quality than the Topeak product.

There's a problem carrying a big frame fit pump on the bike,It doesn't fit anywhere ATM I'm carrying a small one in the rackpack but wondered if there was something better.I have a Mini Morph which is next to useless with big tyres


The Road morph came with a bracket that i've fitted to the top tube but i think you may be able to fit this to the down tube on the Longitude.

by the way i see your front mudguard is really "full" . my Bluemells are nothing like those and don't have a mudflap. ?????


also i see that your rack isn't level. i ordered a set of extra long bracket arms so that i could make the rack level. a bit of extra expense but nice to get it level:

would like some close-ups of the bike if you can ?

thanks

BTW, the gauge version of the Mountain Morph is called the Turbo Morph (who thinks these names up?). I have that one.

+1 for the Topeak pumps

I use the road morph with gauge (gauge isn't that easy to decipher but it's adequate).
