SAFETY BRIEFING.

  • Wear a helmet. Despite recent advances in medical science, brains still cannot be mended nor replaced.
  • Wear gloves or mitts. Hands often hit the ground first. Cuts and grazes invite infection and a hospital visit.
  • Wear eye protection, it only takes a twig or thorn to lose an eye. Crud catchers are a good idea in mucky weather.
  • When downhilling, for your own protection, allow plenty of space behind the rider in front.
  • Bring a bare minimum emergency tool kit and a spare inner tube.
  • Breakdowns are a bore. Plan not to have any by ensuring your bike is in perfect working order.
  • Punctures are also tedious. You can minimise them by fitting latex tubes, slime tubes or running tubeless tyres.

Wheel size does it matter?

Hi,

Looking to buy a mountain bike to come ride with you guys. Rode a couple of times with you but it was about 5 years ago. Don't currently have a bike so looking to get a new one but unsure to get a 27.5 or 29 wheeled machine. Any suggestions or does it not matter?

Re: Wheel size does it matter?

Around this area, this country, nearly every where def 29er. The only time I might possibly prefer a 27.5 is at a very technical trail centre or serious Alpine down hilling.

Re: Wheel size does it matter?

i would agree with Duncan on this.

But my reason is there is probably a better range of tyre choice on 29" compared to 27.7".

And they roll a bit better.

But if the option exists on the bike you want, and the budget will stretch, go for the Boost wheels as they are a bit stiffer and you get better mud clerance.

Re: Wheel size does it matter?

Ok, well trying to get a 29er then. One more question would something around 100mm fork travel be more than adequate?

Re: Wheel size does it matter?

should be fine around here, but it does limit you options for going further afield like the Peaks or Wales.

my old/standby bike has a Fox F120 on it and that was all i used for 8 years, it did bottom out on a couple of occasions, but i'm quite heavy and i don't take it easy on the trails.

as i suggest of you can get the boost wheels that means you can possibly use higher volume tyres like 2.5" and bigger and that will help with the damping.

Wow Adriano, Trying to beat me at my own game?:laughing:

Re: Wheel size does it matter?

Well I have brought a bike, managed to get a used bike for a decent price that's been ridden a handful of times since new.

Now I just need some lights. Any recommendations for a good front light that's under £100??

Re: Wheel size does it matter?

i was going to point you to the "CAM MTB Lights FAQ" post at the top of the list ...... but it looks like we may need to update it a little.
