Monty M5 OS Carbon

Product code: 12105


On order

Monty M5 OS Carbon

Normally only available for Special Order only. Please contact us for more information.

- Monty's top of the range M5 Carbon 20" complete bike, now with some choice updates!
- The 'OS' in the name refers to the new oversized fork steerer tube, which features a 1 1/8" steerer tube at the top cup, expanding to a 1.5" crown race giving far superior frame and fork stiffness and strength at this key area.
- Updated spec also features the new Monty Pro Race 135 freewheel, Pro Race disc rotors and Pro Race disc pads.
- Aluminium inserts at the dropouts and threaded areas of the frame and fork help keep durability up whilst maintaining a super low overall weight.
- A selection of Monty "Pro Race" parts throughout the bike help keep the weight down to a staggering 7.320kg!

This bike is supplied with a 6 month warranty covering manufacturing and materials defects. The warranty does not cover mistreatment or poor maintenance. Please ensure all the details on the warranty sheet supplied with the bike are adhered to. Certain circumstances (such as stripped threads or rounded crank arm tapers) only occur due to a lack of correct maintenance and all manufacturers are aware of these situations, so any claims due to incorrect maintenance procedures are much less likely to be successful.

We build this bike to a 100% complete state in our workshop before dispatch to ensure all items are manufactured correctly and nothing is missing, but we do have to remove some parts to ensure there is no damage during transit. You will need some basic tools (usually 4mm, 5mm, 6mm and 8mm allen keys and a 15mm spanner) for final assembly upon arrival. We have a video guide here to help, but please don't hesitate to contact us if you require any further assistance.

Hello. Don't you sell this with HS33 brakes anymore? Only rotorbrakes?

Posted by Johan on 23/01/2014

Reply from TartyBikes on 24/01/2014

Hi Johan - we have only the disc brake version of this bike in stock. Thanks, Flipp.


What brake clamps would you suggest to use with this frame. Ether washerless design or wash design thanks Lee

Hi Lee - thanks for your question. That would be entirely up to you. If you prefer the extra adjustment the washered design provides then use them, though you would also be just fine with washerless clamps too. Thanks, Flipp.
