Re: Surly Big Dummy Handle Bar Width

11 April 2015 - 7:22pm
Doh! I knew this would happen. I just can't keep still and need a project especially if the Sun's out.

I've sawn off 20mm each side and my initial 'feeling' is that it is more comfortable and it 'looks' more like MY bike. The extraordinary thing is that the saddle now feels like it is in a different position. I find bike/body geometry fascinating.

At least I can fiddle with the saddle but there is no way I can cut the handlebars longer now [emoji88]

Surly Big Dummy Handle Bar Width

11 April 2015 - 3:09pm
Although the Big Dummy isn't strictly a mountain bike I thought this would be the best place to ask. The geometry of the SBD is essentially a MB up front and the handle bars are Salsa Salt flat 700mm. I've fitted Ergo Biokorks with bar ends.

The whole set up just seems VERY wide to me. I know you need the extra stability from such wide bars, but 'as the crow flies' from one bar end to the other it is over 64cm. (Maybe the 70cm is the measurement along the curve of the bar)

I find getting the bike in and out of doors fiddly and there are 2 gates I use where I need to walk the bike through.

There are little calibrated, painted marks under the grips which I assume are suggested guides to where you can cut the ends off. I guess where this convoluted thread is going is: Should I start nibbling away at the bars until I find the width I like? Or should I just leave the set up alone and go with the maximum width considering my loads on this bike will border on the absurd?

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

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

I bought one a few months ago after my Topeak mini started leaking air from the tyres faster than it went in.
At the time it was £23 ish I think and so far I'm very impressed. Got my girlfriends 26x1.75 tyres up to 50psi easily and a club members 700x23 up to 110psi with a smidgen of effort after his mini morph fell to bits, literally. My favorite bit of this pump is the copied from Topeak but superior foot stand. Bontragers effort is an alloy box section which with the steel pin hinging it, slides back into the pumps end for extra reinforcement. I've not got the pump to hand to show this right now, but is a great deal stronger than I experienced with the mini morph.
The hose is nice and long too and the valve thumb lock easy to use.
Utter utter brilliant pump

Yep, that's the one - I haven't needed to use it yet but impressed with the design and feel of it, it's good to gear you've found it works well.

Re: Expected 'lifetime' of a 7005 alum frame??

8 April 2015 - 9:09am
Can any frame experts give an approx 'lifetime' for aluminium? 10 years max? 20 years?

Afraid not as it's not just about the material but the way that it has been put together.

For instance I've had 7005 frames from a certain maker that often broke within the first year, whereas I've had 7005 frames from another that were going strong at least ten years after getting them.

And my Zaskar (which is 6061 I think) is coming up to its 20th birthday and has been ridden hard all of its life.

Expected 'lifetime' of a 7005 alum frame??

7 April 2015 - 2:47pm
I have a quick question: With a short off road ride once each week, plus a 10 mile commute everyday in all weathers, how long APPROX would an aluminum 7005 frame be expected to be roadworthy (assuming of course, no crashes or accidents)??

Can any frame experts give an approx 'lifetime' for aluminium? 10 years max? 20 years?

(I'm thinking about buying a well looked after frame that is now 10 years old)

GBR.

Re: Burly blokes on the pavement - why?

3 April 2015 - 8:52pm
I seem to be winning with bells: a single loud brringg before I'm close enough to make them jump seems to wwork almost every time.

But then, there's lots of bikes around West Norfolk.

I have a little Bontrager mini track pump which is around the same size and weight as the hand pump I had but vastly better for pumping up tyres, I came across it oddly enough when a friend on a Genesis Longitude punctured a wheel a ride and one of others in the group had this little track pump.

Re: Burly blokes on the pavement - why?

I've never seen any MTB groups that ride on the pavement up here, certainly none of the groups I've been out with do that and can't see why they would.

Re: Should I just stick with 26" wheels?

3 April 2015 - 6:56pm
I don't understand why people get so up in arms about wheel sizes, there are advantages and disadvantages to the various sizes so it's case of choosing whatever suits your needs which is pretty much the same with the rest of a mountain bike - there's no one setup that can do it all perfectly so there's always choices for frame material, gear systems, suspension, suspension travel etc.

27.5+ certainly looks very interesting, 3in wide and similar diameter to a 29er that should fit in some existing 29er frames as well as more of the fat bikes. There is an existing 29+ standard but due to the larger diameter it tends to only fit in specific frames for it leaving it too big for 29er frames and a lot of the fat bike frames. It should be a good all round tyre for off road with a bit more traction than standard tyres but not quite the heft of the fat bike tyres.

Re: MTB C2C Ravenglass - Ravenscar

2 April 2015 - 10:20am
I see it covers many classic off road routes along the way. Should be quite a challenge to but a lot if fun. I've swore never to do the Garburn pass again but there again I've never done it W to E. It's one long push from the east.

Anyone have a poploc remote going cheap as I have just bought some new forks and have no lockout remote

Hope you ok after your trip in the ambulance

Re: Should I just stick with 26" wheels?

1 April 2015 - 2:11pm
The best wheel size is usually what's on your current bike, ie I ride an old fashioned 26 hard tail, I'm sure a 29er ht would make me faster given my lack of skill, but wouldn't make nearly as much difference as actually going out and riding more.

If I had to replace / had space and money for an n+1 I'd certainly be looking at clearance / second hand 26 inch full suss bikes where people have upgraded to 650b. The better bang for your buck would override any thought about wheel size issues. I've got half an eye out for a new pair of knobblies and the selection of 26 inch tyres is still way in front atm, so should be safe for many years yet.

As a tall rider, I do wonder if there isn't some advantage to the manufacturers who are now sizing wheels to the size of the frame rather than just fitting all sizes around one standard.

Re: Should I just stick with 26" wheels?

29 March 2015 - 1:23pm
I've got 26" and 29" bikes

I enjoy them both for different reasons.

I have 3 bikes in total

I have a GT Zaskar 26" mountain bike. it's great for single track and technical stuff. the 26" wheels are more nimble than the 29ers so they have their fun aspect but they're not as good over lumps and bump when it comes to speed

I have a Genesis Longitude 29er (fat compatible) running 2.4" X King tyres. it's really good for track and trail routes and rolls over stuff very easy. it's not as nimble on technical routes like the 26er but it a very good allrounder and lots of fun.

I have a Thorn Sherpa 26" touring bike. this is a great bike for what i mainly bought it for which is Touring(surprisingly). the 26" rigida grizzly wheels are strong and very light which is great for exeleration (or hill climbing). I had problems getting wheel parts for my (not so old) 700c Felt touring bike on a trip to Spain not so long ago and decided that 700c was not the way to go for touring abroad.
My 26" wheeled Thorn is great for almost everything. if i had to choose one bike it would probably be the Thorn .

Thorn has some blurb on their website about wheel size and explains why they chose 26". After many years and miles i agree with their stance on it.
They essentially state that the most important place to save weight is on the wheels. Rotational weight is very important and getting bigger, heavier wheels moving is obviously harder than getting smaller , lighter wheels moving. there is also the factor of how common the wheel is when needing parts which i found to be true even in a large city in Spain.
Then there is the strength of the wheel as mentioned before.

I think there is a lot of fad behind this wheel size thing but there is also a difference with them too. You have to decide honestly for yourself , what you want it for and then make the choice.

When touring the main thing that will enable you to complete the trip or get up the massive hill isn't how big the wheels are. it's your mind. People Tour on 20" wheels perfectly well.
It's just a choice.

so , again , i would say , Look at what type of riding you're doing, where you want to do it and then decide for yourself.

To be honest, I'd dismissed you as a serious rider once you'd quoted Thorn as some sort of world authority on modern mountain bike design.
