Re: Moving up from 32 tires to 38/42 - how much of a differe

1 October 2014 - 4:10pm
The cheapest thing to do is to experiment a bit with tyre pressures. If you generally just pump tyres up to the maximum pressure on the sidewall then one or both tyres are probably overinflated. If tyres are overinflated then the ride will be harsher and the tyres will grip less effectively. This document explains the science and recommends pressures for general road use: http://www.bikequarterly.com/images/TireDrop.pdf Mountain bikers or those riding rough surfaces often go for even lower pressures but for a mix of on and off road you have to find a happy medium between on and off road performance.

There is quite a bit of extra air in a 37-42mm tyre so otherwise identical wider tyres should be noticeably more comfortable (again, at the right pressure which will be lower for the wider tyre). I tend to go for the biggest tyres that will fit my 700c bikes whilst still leaving some gap between the tyre and mudguard.

Tyres are the main thing which can be changed to suit terrain. Some people find that suspension seat posts provide a worthwhile increase in comfort over bumpy terrain and some of those can be bought relatively cheaply.

Moving up from 32 tires to 38/42 - how much of a difference?

Hallo,

Firstly let me say I'm new to both the forum and cycling, so apologies if this question doesn't make any sense, is on the wrong sub-forum (it's not a mountain biking question but it is related to going off-road, so I though this would be the best place) or what have you.

I recently bought a hybrid bike (Ridgeback Velocity 2015) for commuting, and am very happy with it so far as a commuting/road bike. I've also increasingly started using it for leisure rides on the weekends as well and have found a route that I like a lot; however some of the route is on a couple of miles of very badly maintained towpath (theoretically paved, but in practice just a mess), and I find cycling on this section quite bumpy and jarring. Another part of the route is a dirt and gravel track through a park; while riding the bike on this is comfortable enough, I've noticed my bike skidding a bit on the track (this may be more my riding skills than anything else). A friend suggested putting thicker tires on my bike in order to both make it a more comfortable ride on rough surfaces as well as hold better to dirt tracks and the like. The bike came with 32 tires; however I think I can go up to 38 or possible even 42. My question is, how much of a difference do you guys think putting on thicker tires would make? In particular, how much more comfortable would it make riding on the rough path? Is it worth it or is the difference not going to be particularly noticeable? Is there anything else I can do other than changing tires to address these issues?

Also, if you think it would improve my ride in these respects, are there any particular tires you'd recommend?

Many thanks.

Idiots shooting a shotgun in the general direction of the Fife Coastal path. Even spent shot raining down through a tree stings.

I haven't been to Coed Y Brenin for about 15 years I reckon. I remember it being great fun. I bet it's expanded a bit.

I did just get back from a week in Wales with my disabled wife though. You have to pay to park everywhere, even to stop in a car park to use the loo. The car park police were hovering like vultures.
I spent a lot of money in Wales, it did at times feel as though they didn't want tourists there though with their parking police everywhere.

Lordy.

Having sunk the best part of £800 all in including accommodation, transport, equipment and food (sourced locally) on a family activity holiday in the UK instead of joining the hordes abroad someone gets their panties in a bunch because I offer information that anyone with access to a map could have found out for themselves - without a shadow of a doubt the money saved on parking by myself (did it once on the last day there) and others would no doubt find its way into the local economy somehow

Regurgawhateveryournameis get a grip, some of us don't have fortunes to squander, and if my saving £5 on parking so I can enjoy it elsewhere offends you do me favour and hold your breath while I look for two damns to give

Re: Coed Y Brenin

It seems to me that it is a car parking fee not a site usage fee. If the OP hasn't used the car park I don't see what the objection is.

Provided of course that it was a safe place to park and wasn't in fact a passing space*, field gate, grass verge (etc.) or obstructing road traffic.

*The ability of some folk to mistake passing spaces for parking places conveniently provided at regular intervals along single track roads beggars belief

You are defending antisocial tightwads who are happy to enjoy a facility but can't be bothered to make a reasonable and nominal contribution to that facility's upkeep.

Aaron,

Ignore him, he obviously doesnt get Wales. this isnt the sort of place where we are after your money.
Or why these cycle tracks are there.

You can come and ride on the Brechfa Forest tracks around here (better than the Coed-Y-Brenin ) any day, any time and because we dont have as many cars to deal with we dont even charge for car parking. It was considered but it will only happen if the number of cars requires us to build car parking space.

Turn up on your bike to the other sites and enjoy yourselves, no need to dig into your pockets.

Croeso i Gymru (am ddim)

PS: Could you post where the car parking is, for anybody who is interested.

There is also a FREE children's playground if they dont want to ride with you as well as the special Child/beginners bike trail at Byrgwm. Did I mention that you are NOT expected to pay to come here or to park, it isnt that kind of money obsessed place. For that sort of holiday try London.

To summarise, you had an amazing day's fun for you and all the family but couldn't bring yourself pay for parking.

That's £5 less for Natural Resources Wales to reinvest in the facilities.

Cheers. Well done you.

Re: Bike recommendations to replace my full susser

For the type of riding you are doing you could probably use a rigid or front suspension MTB.

Off the shelf makes I like are Lapierre and Whyte.

For the generous budget you have at your disposal I would be looking at a custom build. For a lot less I built my own lightweight trail bike based on a Kinesis Maxlight Pro 3 frame. I have 2 front forks for this frame a 100mm suspension and a carbon fibre rigid which I can swap in less than 30 minutes depending on the type of riding I'm going to do.

Another thing to consider is if you are going to have 26" wheels or a 29er.

If you like the Marins then you'll probably like the Whyte bikes too. Quite pleased with my T129 - rarely switch the rear shock off as it works so well anyway when not needed. Quite often I'll lock the front when climbing on tarmac.

As per the title - should have just put a full stop after it!

Just got back from a weeks family holiday in North Wales, made even better by my youngest (5yo) shedding her stabilisers three weeks ago

We all did the Yr Afon trail (nearly 8 miles of traffic free forestry track), then later in the week I did the Minotaur trail with my lad (5.5 miles of whoop and holler, loads of berms, jumps and switchback climbs/descents) and to finish the week off I hired my lad a 24" wheeled bike as an upgrade to his 20" and this morning we did the Fox trail - 8 miles of mean, mean mixed terrain narrow single track

Even the practice/skills section and free ride area is worth going for

Can't recommend the place enough - can now happily take the knobblies off my my bike and put commuter tyres on it ready for my JOGLE trip next year having given it the chance to see what an MTB is capable of it it now being modified into a tourer (did get a few funny looks going round with pannier frames on and bags on the back, the guy in the hire shop was eyeing it up as a classic, and looked thoroughly disgusted when I told him what I'd paid for it!)

Anyhoo - might be my first and last post in the MTB section, but if anyone is planning a trip to Coed Y Brenin and wants to save themselves the £5 a day parking I'll happily point out on a road map where you can park for free and get straight on to the trails

Re: Bike recommendations to replace my full susser

Frankly for that kind of riding I'd consider a cyclocross bike. If you want light then a rigid singlespeed should be around the 9kg / 20lb mark - and with no hills up or down in Cambs could be about ideal...

Bike recommendations to replace my full susser

28 August 2014 - 3:19pm
I've had my Specialized Stumpjumper XC Pro now for thirteen years! Testament to it's build quality perhaps.
I mainly do road/bridleway/footpath riding with the occasional forest trail, so I need something light.
My current bike is full suspension with a lock-out, I don't often have to switch it on, so effectively my bike is mostly a hard-tail but it is nice to know it is there for when I hit the tough stuff.
I like Specialized but I am not partial to it so I wish to consider other makes of bike, my budget is £3000 which probably won't get me a carbon fibre?
I have always liked Trek and Marin but will consider all makes as I am now out of touch, my local shop is a Giant dealer but living so close to Cambridge, I can open this up but am willing to travel further for the right bike/service (most bike shop people I find pretentious and arrogant - so recommendation for friendly shop would be great!)

I'd prefer to get recommendations from people who do similar riding to me - so that's dirt trails, forest, bridleway - mostly flat stuff.

Many thanks in advance!

Blue Hornet.

I use coil oil on all ny off road bikes, its by far and away the most comfortable and plush!

So many hazards. Who knew?

Re: Lesser known hazards for off-road cyclists

Bat. One once flew into me, hit me on the chest. Perhaps it was hard of hearing.
Princess Anne. A friend once encountered one of those on a highland track. Despite the firearms and scary-looking companions, it proved harmless and no impediment to proceeding.
Highland cattle. Rather scary coming across those.
Wash-out. Came across a bad wash-out on a track in NZ. A curious feature is that they tend to create their own raised banks. So as well as climbing over those, there was a very muddy trudge of a couple of hundred yards carrying the bike and luggage separately from one end to another.
