SOLD Pinnacle Dolomite SS Fixed/Singlespeed (Medium/56) Midlands

SOLD
Here's a good condition, simple reliable workhorse. There are a few minor cosmetic scratches to the paint but nothing major.

Currently set up fixed, using a disc mount rear cog and a freehub mounted disc rotor . Can easily be swapped back to regular SS using a cheap bmx freewheel. A quirk is that you can hold the rear brake and “freewheel” the bike backwards.

Spec is as follows:

• 28mm gatorskin hard shell tyres - ideal for avoiding punctures!
  
• 160mm TRP Spyre cable disc brakes
  
• 40cm width PRO bars
  
• full coverage SKS mudguards
  
• Truvative chainset with 46t chainring
  
  • 19t rear disc mount sprocket. Can include 17t and 16t sprockets if wanted
    
    

Looking for £200 NOW £175. Collection only from Bromsgrove, just to the south of Birmingham.

Cool bike - how did you mount a disc rotor to a freehub? Also, does it have a wider mtb chainline to work with that 6 bolt mounted hub?

And how is it fixed if the cog is mounted on the freehub?

It’s not, it took me a while when I first heard of this set up.

disc mount rear cog and a freehub mounted disc rotor

So, the set up was carried out by the previous owner. In practice it rides as a fixed would BUT if you are stationary you can apply the rear brake and 'freewheel' backwards - probably only useful for setting your pedal position before riding off!

The rear wheel is the 'wrong' way round, with the drive cog bolted to the disc mount and the brake rotor bolted onto a freewheel carrier. The chainline seems fine to me, no undue noises etc.

Hope that all makes sense!

Can't tell if it's a good idea or not but i think this is great, GLWS

Dont you still have to pick the rear wheel up because the fixed side is holding the tire to the ground?

Yeah but you can do that with the rear brake on. I think.

What benefit do you get from that. Sounds like your hand is occupied holding the lever then. With the wheel in the air the brake isn't stopping you from moving, in fact don't you have to also hold the front brake to stop rolling away.

Edit:ignore the last bit, you could just lift the whole bike at that point without bothering the front lever

So no different to a regular fixed gear then.

(This took too much thinking about for the train journey home).

Cool bike.

How do you keep the chain tension?

It has an eccentric bottom bracket
