Here are a few links to bike and accessory shops, as well as some camping, clothing and book stores that we've used, says Lynette Eyb.
Bikes and accessories
Wiggle is a personal favourite and we use them quite a bit. They deliver to France (and dozens of other countries), and you can pay in your local currency. I use them regularly for their gift vouchers, which are great for cyclist friends.
Chain Reaction Cycles is among the largest online bike stores in the world – they have an enormous range and variety of bike stuff, from bikes and spares through to clothing. Free worldwide delivery with a minimum spend.
Cycle Surgery started as a bike repair shop in North London back in 1992 but has grown to now have around 30 UK shops and a nice online presence selling leading brand bikes, accessories, cool clothing and gift vouchers. We have a soft spot for them, having bought a lovely Orange bike from one of their London stores many years ago. Free delivery worldwide on orders over £100.
Evans Cycles is an established high street retailer in the UK with an increasing online presence. They offer free standard delivery in the UK, and also have paid-for priority and in-store pick-up options. They deliver worldwide.
Halfords may lack the street cred of the stores mentioned above, but it's come on leaps and bounds in the last few years in both variety and quality, and scored a massive coup in securing the distribution of the Chris Boardman bikes.
Santa got a good deal on my Ortleib panners from SJS Cycles.
For day-to-day stuff in France, we usually go to the local Decathlon, which is where we also bought both our daughter's first and second bikes. They are decent quality and sturdy (though I'm not sure her little brother will appreciate the flowers on the latest model when he inherits it...)
Camping and clothing
If France, see above for Decathlon.
Camping World is one of the UK's largest camping retailers. Their prices are usually very competitive and they offer free UK delivery, as well as delivery worldwide for a surcharge.
Garmin are leaders in satellite and GPS technology and mapping – you really can't go wrong with a Garmin if you're in the market for a GPS.
Cicerone Press specialises in guides for cyclists, walkers and climbers, and have a number of excellent books for cycling in France. They have an online shop.
Stanfords is an excellent travel bookstore, with an amazing selection of cycling in France books and maps. They also have a great range of general travel guidebooks for France, as well as travel literature based in France. They also stock more than 4000 IGN maps. You can order online.
The Bike Ride Shop is a UK-based online shop specialising in cycling guides, books and maps.
