Black Mountains Cycleworks - Bike Repair & Maintenance

If you live in the Abergavenny area, consider using us for your servicing needs.

We typically include more within our servicing costs than with other bike shops in the area, return your bike quicker and offer a FREE Collection & Delivery Service.

I fully assess and quote for every bike prior to commencing any works to ensure there are no surprises. You're welcome to source your own parts and supply with your bike at the time of servicing or leave it to me to use my trade accounts to find exactly what your bike needs.

We don't have a shop, but instead run a workshop nestled in the Black Mountains, just North of Abergavenny. Visit by appointment only to this precise location: ///beauty.lion.bunk (NP7 7NA)

Other Service Menu Items - This is just a sample. If you don't see what you want, just contact us.

Tubeless Setup

- If customer supplies rim tape, valves & sealant: £20 per wheel
- If customer supplies nothing: £42 per wheel
Pricing assumes customer already has tubeless compatible rims and tyres. Note: If your bike already has a tubeless compatible tyre from new, it can be assumed your rims are also tubeless compatible and simply requires valves and sealant. Therefore pricing quoted is purely an estimate.

Wheel True / Replace a broken spoke



Bleeding & Adjustment - £20 per brake including complete flush through and new olive if required

New Brake Pad Fitting - £15 per brake including piston reset, disc rotor true and calliper adjustment. A lesser charge should elements of this not be required

Cable brake & Adjustment - £10-15 per brake.


£20 (1x drivetrains)/ £25 (2x drivetrains) including derailleur hanger alignment

Suspension Servicing

Prices a guide-only as different forks and shocks require different equipment and labour time.

Fork Lower Leg Service - from £45 (+£20-30 for the relevant parts)

Rear Shock Air Can Service - from £30

Dropper Seatpost Service - From £40+ parts

Frame Bearings

Labour cost varies dramatically based on complexity of suspension design and the quantity of bearings. Typical labour costs are £60-80 + bearings which range from £40-70.

Bottom Bracket

Typically £15 for removal, clean, grease and install. Some stubborn bottom brackets can take longer to work on and will result in a slightly higher charge.


Removal of bearings, clean or replace (+parts) and refit with premium grease - £15

NOTE: The vast majority of bikes have straight forward headsets. However, newer bikes are increasingly being supplied with headset cable routing. Bikes serviced with these headsets will incur significant extra charges if headset services are required due to the excessive amount of extra time required.
