Used to do a lot of mountain biking when I was younger but I've not had a bike for years.

Picking up my new one on Tuesday. Couldn't find many reviews but for the entry level price seems to be one of the best spec'd. Can't wait!

Are these seatpost clamps any good? Looking to replace my 60g Giant seat clamp with something lighter, but not sure if these are a bit too light and weak.

I think the steerer might be too short. Even a fully integrated headset takes up a few mm on the top + bottom.
For example, this fsa "zero stack" integrated headset actually has a stack height of 14mm. That would leave 31mm of steerer tub to fit the stem on.

edit: cane creek 'zero stack' has a slightly smaller stack height of 12.8mm, i dont think you'll get much lower than that though.

Right enough. The shortest stem stack height I have seen is about 30mm. It's just buying a problem.
 
Ok techy folks

I've fitted my RD but in small small the chain is proper loose.

I've done the big to big and add two links for the chain.

I can get it to go through all the gears but in small/small and a few above the RD doesn't seem to move back enough to keep up the tension. I can move it back by hand and it takes up the slack but can't see how to adjust it.

There are only 3 adj screws High low and B

Any Ideas
 
Is the bike the chain is going onto full sus MattyG, or hardtail? If it's hardtail do the big to big but don't add 2 links, just make it nice with derailleur at 5 o'clock position and done!

After a bit of trail advice, after a nice destination for trail riding this tuesday, look at wales with options of Afan, Cwmcarm, Landeglla coming to mine does anyone have an recommendations or advice?

Full sus mate. I'm wondering if it's still too big. Its as if the RD is at its limits before its taken up the slack. I can take out some more links I've got spare quicklinks


Not done deglla for a while but I really fancy going a little further south and doing Coed-y-Brenin
 
B screw isn't really designed for taking up the slack on the smallest cog though.

Usually having about an inch or being able to fit two fingers between the chain and the top jockey wheel in the small/small combination is enough. On a double or a single ring chainset I'll try and just have it set was Will suggested tbh.
 
Right MattyG if you want to sort this out and go to town set it all up in the big rings whip the shock out, cycle the rear wheel through the travel to find the point with longest chain growth then adjust the chain length until dérailleur is at 5 o'clock position, possibly near 4 o'clock is possible due to the unlikeness of being in this situation.

Failing that fit 1x10, it's ace!

And yes that is another consideration, liking the look of what I have seen of Afan the Y Wâl trail sounds like a good ride.
 
This is Big-big
Ignore the cable I haven't trimmed it yet and just shoved it out the way





And small-small with loads of chain slack

I now see why those Blur LT frames were on offer, it's no longer listed on their US website so must be being phased out.

Looks like all their eggs are going in the 650b basket, the Heckler has gone that way too now!
 
It's going to be interesting to see the future of the MTB wheel size war. A couple of riders are starting to experiment with 650B in UCI World Cup Downhill. I see 29ers have become very popular in Cross Country events for their ease of obstacle roll over and momentum. The thing with 650B, I'm sure I read somewhere the other day that the actual difference between a "26 inch" wheel, and a 650B one, is actually only about an inch. i.e. 26" wheels are actually about 26.4 inches, and 650B wheels are 27.5 inches. An inch difference, is only half an inch difference when focussing on the radius difference between the two. You could get more difference with huge tyres.

But that equates to around 3 inch per rotation. I've measured it with a mates 650b. So everytime his wheel goes around hes 3 inches further down the road than me.

Yep, a "26 inch" rim is 22 inches diameter and a "650b" rim is 23 inches diameter. It doesnt seem like a huge difference but, as mattyg said, the key measurement is circumference.

Absolutely, but quite obviously, we don't all call for 40inch rims so that we can gain an extra 10 yards on each rotation. I guess the question is, how large can you go without there being a disadvantage or a compromise that is not welcome. i.e. Frame geometry*, Weight of wheel, strength of wheel, cornering ability, wheel base*.

* These two items are being hit by manufacturers. I saw only the other day the new Trek (I think?) bike that has squeezed a 29er into pretty much the same space as a 26er.

I think the problem with different bikes having different wheel sizes is that it just becomes another furstration for the consumer. Another non standard that has to be decided on. Less large batches of bikes from each manufacturer where they are pushing different wheel sizes and hence more bikes, equates to higher prices generally. Is 650B a "niche within a niche" and too little difference over 26? Will consumers ever get used to the look of 29ers?

Interesting to see how things go. I welcome change and competing standards personally. I can't quite get used to the 29er concept but I reserve judgement until I have ridden one. When or how that comes about I don't know. Demo days?
