The Shimano method is best if you ask me (you obviously need compatible gear). You basically attach a reservoir (sold at various place) to a port at the top of the system and you squeeze fluid in using a syringe at the caliper. Very simple, no mess.

Registered 10 years agoThese are Tektro brakes - having finally bothered to look at the instructions, that's basically what they suggest too - with a tube attached to a bag at the reservoir at the top end. I was looking at it the other way round, thinking I would push oil through from the top to bottom. Still need tubing though, tubes at my local aquatics centre were too big!
Edit: Looks like washer hose is about the right size...

Registered 10 years agoYeah, that's what I thought, but as I say, they were too big from the first place I looked (mainly ponds as opposed to tanks)! Only concern is that without the nozzle that fits the reservoir at the lever end, it could get messy. Might have to suck it up and buy the Tektro bleed kit for that alone.
Got a bit of grace though, even just opening the lever reservoir up has somehow given me a bit more power which was sorely lacking - didn't fancy taking it out in the wet otherwise!
Really, really should get round to buying that maintenance manual! LBS wanted £15 to do both brakes, sod that!
Edit: Have asked CRC whether the Shimano funnel fits Tektro reservoirs!

Registered 2 years agoSo... did the London to Brighton off road BHF event on Saturday.
Great fun - only the middle third felt like proper mountain biking. The first third was on the Thames Path and most of the last part was on the Downs Link.
Two big ole hills though including one near the end at about 70 miles which was a bit of a killer. Nice at the top though to be able to look down over Brighton from above.
Two weeks of dry weather made it nice - biggest problem was dust. Had it been wet I imagine parts of it would have been stupidly muddy with 1500 bikes going past!

Unfortunately I can say from experience that the Park stand you're linking to isn't up to their normally quality. Which is a shame.
I have this one http://www.evanscycles.com/products/feedback-sports/sport-mechanic-bicycle-repair-station-ec011372

Registered 5 years agoMade a lucky call on Sunday morning. Waking up from our overnight bivy in the Cheviots, I called an easy day and a fry up somewhere.10 miles down the valley instead of a 20ish loop back to the car.
Just rolling back into the carpark when my freewheel broke. I would have been seriously screwed if we'd been more adventurous.
Amazing weekend, there's a section of the Pennine way that is also a bridleway, it's a paved track running along the Scottish border on a ridge. A real money shot for the picturesque. -

Yes, I've had two over the last five years and well worth it. Even the slightest tweak can make a lot of difference if the fitter knows what they are doing. I've had a BG fit with Specialized (one of my training partners does them) plus I've been fitted by the BikeWhisperer. Both very good with similar approaches, and BW was taught by Steve Hogg who is one of the advisors for cyclingnews.

I personally wouldn't bother with any fits that cost less than £50.00 though. You need to spend a few hundred or so I think to get a decent fit. Plus the like of Specialized or BikeWhisperer will offer a free consultation after the first fit.

Registered 7 years agoI've seen that they seem to scale up quite a lot from the basic (your seat height must be X and your seat should go X back) to the full on (we're going to measure almost every part of you, calculate a bunch of angles and then tell you exactly what length all the different bits on your bike should be).
I wouldn't mind having my cleats set-up properly too. I'm not getting any pain from mine (nor any pain in my legs) but they definitely don't quite feel right to me since I put in a new pair.

I find it much more comfortable to move out if I'm matching speed with the traffic around me or on quieter country roads with less traffic but higher speeds. In the country, I want to make absolutely sure that whoever's coming up behind me at 25mph in excess on my speed can see me as early as possible.Cubby didn't know how to turn off sigs!

I also move into the whatever position gives me the best visibility on country lanes, or whatever position gives drivers a greater braking distance in which to slow. I also check behind as often as I do in a car.

I did quite well without one for a few years and you can get yourself pretty close with a turbo and some common sense, but after a few years my goals were different and I wanted to get fitted properly to try and make myself faster and more efficient on sportives. You really don't appreciate how good a fit can be until you've been on the bike for a few hours. For example, I fitted myself in the early days and was ok for 2-3 hours. Once I started getting into 4-5 hours I felt there could be improvements made in my position. A fit corrected a few minor issues and from there I just felt more comfortable. I couldn't imagine doing something like the Marmotte (9-10 hours in saddle) on a bike that was only "nearly right".
Getting your cleats set up properly is one of the most important things to do, and both my fits were from the cleats up. Fits will ensure you are as efficient as possible on the bike and even before the fit starts a good fitter will check how flexible you are before you even get on the bike. You could have exactly the same measurements as another rider but they could be a bit more flexible than you in some areas. This would mean a slightly different set-up.
The cheaper end of the fitting market I find is little more than sticking you on a turbo and putting basic formulaic measurements and that's not good enough. Everyone is built differently.
So back to my original point, it depends how serious you are and what you want out of it. -

Registered 7 years agoI'm not particularly serious at all, but, I certainly want to increase my comfort on the bike and reduce the likelihood of injuries (I'm an old man now, everything takes so long to heal).
But yeah, I want to be able to do 6 or so hours as comfortably as possible so I guess it's not a bad bet.This post is sponsored by Apple and the iPhone 4S. Think different.

Registered 10 years agoIt appears I have failed the man test. Bleeding these brakes is more problematic than I thought.... Thought I'd sorted it once with minimal fuss, couldn't see any air end to end, but they were still spongey. Spoke to the LBS and they thought that as the bleed nipple ony brakes is at the bottom of the caliper, it's likely air was still trapped inside the caliper.
So I took the caliper off and dropped it so the nipple was higher and tried again. This time was a disaster, with the tubing coming off numerous times until there was mineral oil everywhere! Ended up with me in a huff and brakes that def don't work! Will have another go tomorrow.... -
Bless. I ended up doing my nephew's when my (cunt) local bike shop utterly failed to do anything. Bastards charged us for it though and then said it was just because the bike had been hung up and it would settle (or something).
I followed the process in the Shimano manual which came with the bleed funnel. Was pretty much perfect after I'd tilted the reservoir to get the last few bubbles out. Don't forget to hit the tubing etc with something too to get rid of the trapped bubbles.
(Also, I ended up with the tubing coming off once because I hadn't loosened the nipple enough. Sprayed oil all over my shoes.)This post is sponsored by Apple and the iPhone 4S. Think different.
