Bike broke (26 inch MTB) - need new one quickly :(

[mauvais]

Looks good! Look after it!

 

[gentlegreen]

It's the sort of bike that could get a pensioner into trouble

 

[gentlegreen]

I imagine this is what I need to put different cogs on ?

 

[gentlegreen]

9 speed - so I'll need to buy new cogs and stuff ... or fit my SRAM bits ...

 

[Sprocket.]

Put thread on ignore due to gratuitous use of the unfit for purpose word ‘cogs’!
My heart is broken.

 

[gentlegreen]

Seems I just whack the crank with something soft
So what I have is "Shimano Hollowtech" ... so I need one of these ...

 

[two sheds]

I have raced on or mechanicked for MTB and road racing teams for 30 years. You pick up a thing or two...

Still no excuse

 

[weepiper]

That's hollowtech II not octalink. Why do you want to change it?

Currently it has 36 and 23 (I think) tooth chainwheels - whereas I live on my 38 tooth middle one and most days I feel the need to change up to 48 for a bit - I know they wear out quickly, but I like my SRAM X4 and I have a couple of spare 11-34 8 speed cassettes.

I find the 9 speed Shimano shifter a bit vague ...

 

[gentlegreen]

I now have a bike worthy of my OMM rack
Next stop Carradice panniers...

A Park BBT-9 will do your crank bolt and your bottom bracket so that may be a better buy.

If you are not given to lubricating correctly the plastic tensioner bolt (as Shimano calls it) then eventually you will need a Park BBT-10.2 to get it out so just buy that now. The 10.2 is also useful because it can be be in conjunction with a torque wrench to accurately torque the TB to the 8Nm recommended by Shimano.

A cog is a toothed wheel which directly engages another toothed wheel. THESE ARE NOT COGS. There are no cogs on a bike unless you have an IGH.

 

[gentlegreen]

Somewhat worryingly the tensioner wasn't even finger-tight !

 

[gentlegreen]

I wish I'd upgraded to hollowtech - I'm going to actually clean my transmission properly now !
To which end I will cough up for the proper tool.

 

[gentlegreen]

Bloody hell - so many standards !
I was so relieved when I stopped having to carry a hammer with me that I quickly decided square taper was the bee's knees ... but I swear my chainwheels got closer to the frame every time I serviced mine ...

My biggest issue as someone who only does pedals and bottom brackets once in a blue moon is the direction of thread.. I always have to look it up to remind myself..

Congrats
Im about to go out and hopefully pick up this thing for £200
always a bit dodge buying a second hand bike, but i think the seller is a bikepart dealer judging by his ebay account
Ah the days of Loot and bikes for £20

 

[gentlegreen]

ska invita that bike is looking very appealing right now ...

After hours and hours playing with it and swapping parts ...
Previous owner must have had shares in Loctite - and I need to get a peg spanner to remove the chainring - never needed one in all the years I've been pottering ...

Whereas my old bike felt like a Volvo estate or maybe a Landrover, this one is a bit frisky even with the fork locked down.
I may yet relent and buy something else and have this as a spare bike

It doesn't help that I'm a bit under the weather...

I had to over-extend the seatpost by half an inch so that's another expense - looks like I can get a 400mm ...

Dare I ask why you are taking it apart?
I know nothing about bikes so moving the saddle is as brave as I get

It was set up as a semi-serious downhill mountain bike whereas I want something for commuting - but only for another couple of months - thereafter it will be mostly 20 mile picnic and fitness rides (I trundle there and ride home with a bit of enthusiasm) - but I also want to get into longer rides again - possibly with the CTC - I rode 70-odd miles in a day several times on my previous bike - so I need to raise the gearing - not that i don't appreciate having some low gears ...
But I'm sensitive to teeny changes in saddle height so it was always going to take a bit of getting used to ...

I ride on rough tracks and roads so have always appreciated the solidity of a MTB.
My old chunky cheap suspension fork was locked up solid and I kept meaning to take a chance on a steel fork - it may explain the shoulder nerve problem I have ...

I actually also own a Specialized steel-framed non-sporty hybrid that I fell out of love with - not least because the suspension handlebar mount got sloppy and the warranty replacement soon went the same way and the back wheel didn't like me so I ought to have a go at fixing that up...

 

[gentlegreen]

I was going to buy a dropper seatpost anyway - so perhaps I'll do that ...

 

[gentlegreen]

The size is similar, but the top tube drops towards the seat tube so I've had to mount the saddle very differently ...
Since I've stopped winter commuting, I won't need to fit the several pounds of lighting rig to the front - which undoubtedly affects the feel ...

 

[gentlegreen]

Here it is nearly done.
Since I couldn't get the teeny 36 (?) tooth chain ring off, I'm still on the 9 speed mech and 11-32 cassette so my top speed is somewhat compromised .. I just ordered a peg spanner..
I guess I'm not used to riding a lightweight machine with give in the fork and brakes that work a bit more acutely ...

Those seat stays are very spindly so I think I want to find a different method of mounting the rack struts... probably two new struts connecting to the seat tube union ...

 

[gentlegreen]

Bloody hell, my new spare wheels with 2.5" Maxxis tyres are massively heavy - I'm amazed people ride around town on them ... wheels are Sun Rims S-type (riveted I believe) on Deore hubs.





But I can see myself being less hesitant to drop off kerbs - there's movement in the fork even with everything tightened down.

Just ride it like you have nicked it!

Especially as that bike cost $4,000 apparently !!

Let "Pil" be your guide into the world of ultimate epicness.

 

[gentlegreen]

I see he's missing a front tooth

er, NO BTW !

 

[two sheds]

Why a tricycle ?
I wish I could find the advert for these bikes.



EDIT :-

I didn't answer this - when I was young and cycled loads I found it really easy turning round to see behind me while keeping a straight path. Not sure how bikes have changed now but they're much less stable so if I turn round now I start swerving across the road . I think a trike will sort this

I'm sure a mountain bike is better for that than an old school 10 speed (with toe clips ?) - it's a key reason I ride one - it's all about control ... modern carbon racers with clippy pedals will doubtless be a whole different kettle of fish ...

 

[two sheds]

I do have a mountain bike but have found that just as bad - they're just not as stable as they were, I wobble all over the place. And if I ever tried toe clips I'd slowly topple over at the first junction.
